Business as usual... if you aren't making enough money from your customers, lie to them...!!!

"I have yet to receive negative feedback from either of the courses. So why not spend less than 5 mins of your time to help improve others' diving safety and performance by letting them know what you thought of the classes?"


THAT IS NOT TRUE GARETH...!!! I GAVE YOU NEGATIVE FEEDBACK... 


Yes, I am the ONLY one, but sending an email out that says you have yet to receive negative feedback, that is a lie! As far as your wish to "save me from the undue negative attention," I don't need to be protected. I've been very vocal about what is wrong with the dive industry and how to fix it. The problem continues to be that many are focused on "business as usual" and to change anything would result in negatively impacting their pocketbooks!

You have just did exactly that which I
detest; you lied to your customers!

At this point, I am literally ready to give up on scuba diving education! Your program is successfully moving through all of the major players in the scuba diving industry. Now, you have people making video reviews about their experiences with you! Here is a video review from Terrence Tysall, NAUI Training Director: https://vimeo.com/219218352



You have found a niche that I really think that needs to be addressed, but again, I can't emphasize enough to anyone that is actually going to hear it, this is NOT new. Where my frustration lies is that you are traveling around the world and sharing these insights and crap is still hemorrhaging out of the dive community. This doesn't mean that you are going to single-handedly going to be the catalyst we've needed, but that I want instructors, agencies, and dive shops to start treating students like people and get the target off their wallets. I believe everyone has the right to make a living, but if the part of industry that is responsible for divers dying won't do anything about it, scuba is dead!

Vimeo: Why ‘human error’ is a poor term if we are to improve diving safety. NAUI ICUE

"Presentation given by Gareth Lock and NAUI's ICUE 2017 event held at the Long Beach Scuba Show, LA. This thought-provoking and controversial presentation will focus on the need to change attitudes to human error in diving. Using audience participation exercises and diving case studies, he will show that the factors that we attribute to incidents and accidents are only really visible after the event because we are biased with hindsight and know what the outcome was, therefore we are able to join the dots to create the incident. However, in many cases, divers are unaware of which dots to look for, let alone that they will create a picture once joined up. Fundamentally, if ‘human error’ or ‘diver error’ appears in the conclusion of an accident or incident report, the investigation stopped too early. He will go on to explain how training which he has developed by taking the lessons learned from aviation and healthcare can improve individual and team performance in diving, making it a safer sport."

Comment on, "Edgewater diver who drowned at Blue Spring still had air in tank" The deadly quarter turn back!

Yes! Always open the tank valve all the way...  NO quarter turns backwards. #scuba #tankvalve #noquarterturnback NAUI has this written in their literature for some reason, but I teach to not do this...

The deadly quarter turn back!



An Edgewater diver who drowned at Blue Spring State Park had plenty of air in his tank but, its air valve was only partly open, according to a report from the Volusia County Sheriff’s Office.

By Frank Fernandez / frank.fernandez@news-jrnl.com

An Edgewater diver who drowned at Blue Spring State Park had plenty of air in his tank but its air valve was only partly open and he was not certified to dive as deep as he did, according to a report from the Volusia County Sheriff’s Office.

Samuel Slack, 36, drowned on Oct. 9 after he had a problem with his air supply and an attempt at buddy-breathing failed with his diving partner, Daniel Vansickle, 37, of New Smyrna Beach, according to reports. Slack "showed no signs of apparent or obvious injury" and the autopsy determined his death was an accidental drowning, the report states.

Keith Sterner, the owner of Sea Dog Dive Shop in New Smyrna Beach where Vansickle earned his open water and advanced certificate, said an out-of-air diver can quickly panic.

"It’s scary to see people panic," Sterner said. "You see grown men do things you wouldn’t think they’d do. A lot of times you can’t control someone in a panic and the best thing you can do is to save yourself."

Slack was the first diver to die at Blue Spring in Orange City since 2009 when Robert A. Jones, 38, of Zephyrhills drowned while "free diving" without air tanks.

Vansickle told investigators the men had been diving for several minutes and were about 80 feet deep when Slack made a "throat slash" gesture to show he was having trouble breathing, the report said. 

Vansickle said he passed his regulator to Slack so he could breathe from it. 

But when Vansickle motioned for the regulator’s return after about 30 seconds Slack held on to it, the report said. Vansickle told deputies he then pulled away from Slack, got control of the regulator and swam to the surface. 

Once he surfaced, Vansickle yelled for a maintenance person to call 9-1-1, then dove back down and found Slack motionless in about 100 feet of water, the report states.

Vansickle could not be reached for comment.

Vansickle worked with Slack’s wife, Krystal, at The Garlic restaurant in New Smyrna Beach and had known Samuel Slack for about a year and a half, the report said.

Slack’s tank had about 2,100 pounds of pressure/air, the report states. 

Corbin McKeon, an employee at Spruce Creek Scuba in Port Orange, said in a phone interview that depending on the type, tanks can hold from 3,000 to 3,500 pounds of air. 

Slack’s tank valve "only turned less than one quarter (1/4) of a turn to shut off, this is not a normal operating position," the sheriff’s report states. Another part of the report said it turned only a quarter turn. Sterner said he teaches students to open the valve all the way, which can take several turns, and then turn it back a half-turn. 

"If the valve isn’t open all the way, it can create labored breathing," Sterner said.

Slack had a novice open water diver card, meaning he was not certified to dive any deeper than 60 feet, the report states. Both Slack and Vansickle initialed a document at the park that they would not exceed the limit of the least certified of the two, meaning that they should not have exceeded the 60-foot depth.

Vansickle was certified as a cavern diver and his gear included an extra regulator to be used by a buddy to breath during an emergency. 

But the additional regulator was under the chest straps of Vansickle’s "buoyancy vest, making the regulator unavailable if needed," the report states.

Each man’s wrist-worn dive computer showed they dove to 116 feet to the bottom of the spring and remained there for about 2 minutes. 

They ascended to about 80 feet where both computers showed that they stopped for about a minute. 

Slack’s computer shows he then descended to 90 feet and remained there for 8 minutes, the report said. Then Slack "immediately" rose to the surface.

Vansickle’s computer shows the same depths and then Vansickle rising to the surface as Slack remained at 90 feet. 

The computer shows Vansickle immediately descending to 90 feet and then immediately returning to the surface. The computer information is consistent with Vansickle’s account and his decompression sickness.

An investigator tried to formally interview Vansickle, but on advice of his counsel "he refused to cooperate further during the investigation."

Looking for a Great Scuba Instructor is Like Looking for a Great Real Estate Appraisal

I currently have a student that is a real estate appraiser. He's been doing it since 2004. Today, we had an opportunity to talk about his business and how appraisals work. I found a lot of correlations between being a scuba diving instructor and an appraiser that I'm going to talk about in this blog.

I worked in the banking industry from 1996 to 2006 so I'm not unfamiliar with the appraisal process. During that time, as many of you might remember, home prices rose at an unprecedented rate! As all "bubbles" eventually burst, so did the housing market. 2008 was a bad year for home owners that needed the equity in their homes. Knowing how much a home is worth is dependent upon the real estate appraiser.

Contrary to common beliefs, appraisers go through a rigorous training process including a two year long apprenticeship. It's not just about spending time on the internet looking in the neighborhood for what others have sold their homes for, but for comparable upgrades, downgrades, landscaping, neighborhood conditions and many, many more aspects that are often unknown by the general public.

The appraiser is sometimes thought of as the "bad guy" because they are often the bearer of bad news. While experience creates consistency in the process and techniques an appraiser uses, once that foundation of experience exists, it can be counted upon to be consistent over time and not be compromised. In the process of buying and selling real estate, if someone wants to sell their home, in the end, it's only worth what someone is willing to pay. This "market value," especially today often comes at a premium to "appraised value" due to a lack in the supply of homes in areas well established without the land for new constructions.

Home buyers want values to come in low so that they pay less. Home sellers want their values to come in high as to make more money... All the while, banks want the value to come in where it should be as to minimize the risks involved in the fluctuating loan to value of said property. The appraiser's job is to be impartial so that everyone's best interests are insured, but the best interest of the economy is very important as well. Here are some similarities between the real estate appraisers and a scuba diving instructors I found fascinating.

When the consumer (prospective student) is ready to sign up for scuba diving lessons, often, one will do a search for and compare prices of lessons in the market they live in. Market prices sometimes influence what the dive shops (or independent instructors) can sell the lessons for. While prices vary in different parts of each respective town, they also vary from state to state, especially in land-locked states versus states (and to that extent, cities) that are near water.

One of the topics we talked about was the value of homes versus what people were paying for them. As home prices rise and availability decreases, buyers are often willing to pay more for a home than it's worth. Years ago, the purchase of a primary residence often meant that one would count on living there until the home was paid off, children were raised, moved out, off to college, etc. It is not unheard of that today's buyers will jump from home to home as they jump from job to job. Because of this, it is realistic to expect that the value of a home (a place to live, a place to raise a family, a place to retire to) -- the intangible investment that comes with home ownership -- is replaced by believing that a primary residence can be an investment vehicle! As what I expected would happen in 2008 saw my departure from the banking industry in 2006.

There is a preponderance of home buyers today, again are starting to believe that a primary residence makes a good financial investment. Family structures, career goals, financial goals, and changes in communities are occurring quicker the events that ran concurrently with home ownership that encompassed a traditional 30 year fixed-rate mortgage. In years past, home owners had time to wait out the highs and lows of market fluctuations. As the decades pass it was likely that one would expect a return on the cost of financing a home over a 30 year time frame. Today, there is little to no expectations that one will stay in a home for 30 years. Relatively speaking, it is unheard of! As lifestyles changes decrease from decades to years, so does the expectations of waiting out the tides of housing and financial markets.

Scuba once was an activity that took considerable more time to complete than the programs of today. The ability to choose from activities never before open to the general public that were few and far between, today are open to everyone. The instant gratification that comes from promises of learn today, dive tomorrow is because the industry created programs to meet "market" demand. The unfortunate side effect of speeding through an activity like scuba diving is that more drop out, more are less qualified, and more end up having to unlearn bad habits that might not have been learned in educational programs decades before.

There has been a movement in the industry to undervalue the price associated with learning how to scuba dive. While it is logical to conclude that when groups of students get larger and thus would influence the price of what each student pays, regrettably the prices have dropped but the cost of running the programs have not -- in fact they've gone up! What that means for the industry is that in order to finish the program and award certifications, programs that once had extensive training requirements and the months to learn, don't line up with today's students with limited time on their calendars. This means that programs ultimately became condensed and instructors took shortcuts. Programs that don't get the students in and out are thought of as outdated or inefficient.

While it is still possible to get adequate instruction at current market prices, as the old saying goes, you get what you pay for. It's no difference in real estate and it's especially true in scuba diving. It is reasonable to find that most dive shops will make so little profit on education that if it wasn't for equipment sales, they would no longer be in business. In order to maximize time and value, what ended up happening is that selling equipment became the priority and teaching became superfluous.

Value for services that are undervalued only result in one thing -- divers that don't know how to dive -- we are seeing it in today's students.

Here are some other correlations:
  • Banks want to pay less to appraisers in favor of "automated value models" (electronic appraisals)
  • Agencies become more receptive to e-learning and electronic methods of instruction

  • Real estate agents put pressures on appraisers for higher and unjustified values so commissions are higher
  • Dive shop owners put selling pressures on instructors to sell equipment as education doesn't have immediate or perceived value

  • When experienced appraisers (receiving higher compensation) leave the industry, less experienced appraisers settle for smaller paychecks just to get a job -- get into the industry
  • Dive shop owners pay less to their instructors due to increased operating costs, passing those expenses onto "up-and-coming" new instructors that settle for lower wages because of the touted "benefits" that come from working as a dive professional

  • As experienced appraisers leave the industry, newer inexperienced appraisers enter that may be manipulated by lenders and real estate agencies
  • As experienced instructors retire, they are replaced by younger instructors without the experiences that the wisdom of decades of diving and various situations brings

  • Home buyers are paying inflated home prices that are contrary to prudent financial planning because of the belief that the benefits of "home ownership" are greater than the actual costs (and savings) associated with renting
  • Dive shops entice prospective students into signing up with all inclusive (resort-style) training and pricing -- one low price that covers everything -- no investment in themselves as a diver that can't be continued upon returning home

  • State and Federal regulators are influenced by banks, lenders, and the real estate markets to approve riskier lending and financial products with questionable underwriting standards
  • Certifying agencies fail to hold their instructors accountable for failing to follow standards and training guidelines without repercussions because they are in the business of selling scuba, not making divers



Response to Cave Diver Harry's Facebook Post, "You may have noticed a couple things"

https://www.facebook.com/story.php?story_fbid=1952878454982592

• While I’m often critical of certain common teaching practices that can have an adverse effect on the environment or diver enjoyment, I seldom (if ever) label a particular teaching methodology as “unsafe.”

That being said, it begs the question, "Are a preponderance of divers that are seen in these videos FROM a 'certain' agency?" If so, why does this correlation exist?

• I also never comment on actual incidents that may have resulted in diver injury or fatality.

As social animals, it is inevitable we want to know what happened and why... we slow down on the highway to rubberneck all the time. As far as the number of fatalities, while scuba is dangerous, so is: rock climbing, bungee jumping, hang gliding, skiing, auto racing, bicycling, football, horseback riding, polo... Zero fatalities would be great, but that is unrealistic.

There is something to be said about "accident analysis" that can be used to help us not make the same mistakes we did before. Accident analysis was part of my cave training and I find it an invaluable tool in all fields, not just scuba. We think we won't make the same mistakes we did before, they did, or make the mistakes poorly trained divers make. This is called "hindsight bias." Because we saw, read, heard about that kind of accident/fatality that we won't repeat it because we know about it, but it continues to happen...

• Why is that? It’s because our friends in the legal profession regularly cruise social media looking for ammunition they can use when suing dive instructors. And we are all paying for it.

I think the industry's insurance is expensive because insurace companies want to make mconey. To that extent, if instructors stop doing stupid shit, if fatalities fell into the category of freak accident, then scuba liability insurance might not be as expensive as it should be.

As I write in one of my blogs, I think that families pursuing financial compensation to activities their loved ones entered willingly is wrong as well. I've made it perfectly clear that in the event of my death while diving, no one should pursue legal actions. I fully accept the risks involved, I even understand that a few out there might even cut corners, however, I have done my due dilligence, I have made educated decisions, and I chose to go diving! If I die diving, I ONLY want to be remembered for the things I contributed to scuba, not the one mistake I made.

• I just got my bill for liability insurance for the coming year. As expected, it is going to be in excess of US$1,000. And even though this is nearly twice what I was paying just a few years ago, I’m not complaining. I’m just happy to be able to get it at all.

I think mine has doubled in the last 10 years too, however my automobile insurance has always gone up and I have no tickets, accidents, or claims. It is the cost I have to pay to drive.

Similarly, when I did my crossover from SSI to NAUI, my course director went over the costs of being an instructor. I never got that at SSI. If the instructor doesn't make a business plan setting dollars aside for unforseen repairs, annual dues, liability insurance, program supplies, to what extent do they expect to remain in business? Some do a better job of running a business as a business, while others insist on teaching for free or close to it. I will make money teaching scuba. I will not do it for free!

• The number of carriers willing to insure diver training have been steadily declining. It wouldn’t take much for it to simply become unavailable. If that happens, few of us are likely to be willing to teach scuba when the cost of doing so could be everything we own and everything we are likely to make for the balance of our lives.

If the insurance industry left us, wouldn't it be prudent for the certifying agents to create their own form of safeguards against potential damages? Perhaps union style dues? That money to be set aside like insurance monies are? Maybe even partner with everyone in the industry to work on legislation to cap claims on financial awards? We have attornies creating the liability releases... What is the purpose of those?

• So, by all means, keep posting about how “unsafe” you think certain instructors, dive operations or training agencies are. Keep playing armchair quarterback, passing judgement on recent fatalities about which you actually know very little.

That does make for an interesting dilemma. I don't recall industries evaporating because of people's opinions but I have seen how reviews from sites like yelp have impacted individual businesses... I see reviews two different ways. Are merchants providing the services the consumers are looking for which warrant only 5-Star reviews? Bringing to the industry and emphasizing what the consumer can expect... or, are the reviews a reflection of what has already happened in the industry -- the merchants have disenfranchised the consumer with expectations beyond what can actually be delivered? -- that everyone can become a diver this weekend.

Reviews also don't seem to turn the consumer away when others warm them of certain business practices. In all, I believe the relationships people develop with each other will be the greatest hedge against frivolous law suits. Integrity, trust, accountability, and respect are earned -- NOT GIVEN!

• It doesn’t matter that, in so doing, you may be contributing to the end of diver training as we know it. Because, when that happens, people will just teach themselves by watching videos like this on You Tube.

Perhaps, however mentors, artisans, masters, and the exceptionally skilled have always been sought out even when cultures might be moving in a different direction. The Socratic Method is a great way to teach and to learn.  I do have to say, I don't find a plethora of videos showing and criticizing GUE, IANTD, NSS-CDS, NAUI, TDI, BSAC, or even YMCA... I believe there is a reason for it.

Today's culture has strongly moved towards the inclusion of "everyone." In the workplace, education, social dynamics, and religion, I think this is a good thing. But, to include everyone in scuba is wrong. The primary reason is that many can't do it well enough to not hurt themselves. Sorry, but if it is likely you are going to kill yourself or others undergoing an activity, you should not do it and if your feelings are hurt when you don't get that c-card, too bad. I will not award anyone a certification card just because they paid for training.

Thank you for the continued perspectives, Harry!

Scuba Review, Refresher, and Evaluation Program for Divers Out of Practice


If you would like to take an "educational only" version of this course, I offer the online text, quizes, final exam, and review of the contents within the "Solo Diving" educational presentation. A certificate of completion is awarded after your completion.

There is no diving involved, but there is a lot of good material to read through and add to your skills set. It can even help you to become a better dive buddy!

Lastly, as a special gift to you, you'll get a personalized  evaluation of your current diving experiences and practices which we'll create a plan of action for your future diving goals and ambitions.

Take a sneak peak, here: https://jcaelitescuba.com/solo/e-learning/ch1-intro.htm

This certificate is not recognized by SDI, other certifying agencies, or myself as a "Solo Diving," "Scuba Diving," "Open Water," "Specialty," or "Ranking" program. Completion of this certificate program cannot be applied toward the SDI Solo Diving Course. I am offering these insights to solely improve your mindset as a diver especially if your skills have degraded or if you feel your existing certification left out a lot of the education on situational awareness, gas management, and risk assessment.

Response post to, Cave Diver Harry: "Every dive is a solo dive."

Response post to, "Cave Diver Harry: "Every dive is a solo dive."

http://cavediverharry.com/solo/



I agree that every dive is a decompression dive. Just because one off gasses at 1 atmosphere instead of 4, 3, 2, etc... are just semantics...

However...

Every dive is a solo dive; I disagree! Semantics aside, one can dive with a buddy or not dive with a buddy. In only but a few set of unique circumstances would separation from one's buddy occur, but then it would be just until those moments later reunited underwater or on the surface -- but being in the same ocean but too far apart to be of assistance is a choice. 

The choice to pick up your cellphone while driving or to drive faster than conditions allow that result in injury or death are labeled "accidents;" something happening out of our control or ability to prevent -- but the reality of it is, you don't have to text and drive and slow down when it's raining/snowing/icy...

So, just because the inevitable happens -- poorly trained divers get separated -- that is an excuse. 

Training on diving with buddies is just about non-existent as is diving in large groups. That is an instructional issue first, then followed by the lack of experience. The two greatest culprits in separated buddy teams are buoyancy issues and the flutter kick!

If you're buoyant, you are where you are in the water column and one is not chasing after another or seeing them floating off to the surface like a helium-filled balloon. The second, slow down. Flutter kick has the expectation of always having to have forward momentum. Consider the modified flutter or modified frog kick. Just enough momentum to move one forward and when you stop, you remain neutrally buoyant.

I dive in the PNW in sometimes zero visibility. When I am with a student, I prefer them on my left so if needed I can reach out and put my hand on their bcd or finger through a d-ring in order to stay in contact. When they are on my left, they are also able to still operate all their equipment without feeling that their dive buddy is crowding their space while still having unrestricted access to their inflator and SPG...

Lastly, situational awareness! You have it or you don't. Consider watching this: 

https://youtu.be/lFp3dup_s3s



I tell students to keep your eyes on the road in front of them. Stop thinking like you're still on land. One can only see directly in front of you with direct line of site so if you have to helicopter to find your dive buddy, you're too far away... with just a turn of your head, your dive buddy should be there!

[ On the extreme side of the training I do, "SDI Solo Divers" and technical dive training get the situational awareness beaten into them... boot camp style -- break them down to build them up again... Yes, the solo diver course means one will dive alone, but the dive is planned that way, then dive that way -- no "accidental" separation... While I believe in diving with teams on tech dives, due to ceilings or deco obligations, I also train for contingencies that reduce the risk of two victims... those variables can include (but doesn't have to) one diver finishing their obligations and leaving bottles hanging for others to continue in water emergency decompression, but again, these are in extreme cases, not recreational divers that get lost like kids in Wal-Mart! ]

May 18, 2017 | ANOTHER DIVER ON A REBREATHER DIES | "Devon diver died after plummeting 60 metres to the ocean floor without his breathing apparatus on"

ANOTHER DIVER ON A REBREATHER DIES

May 18, 2017, at: http://www.devonlive.com/devon-diver-died-after-plummeting-60-metres-to-the-ocean-floor-without-his-breathing-apparatus-on/story-30340313-detail/story.html

"Devon diver died after plummeting 60 metres to the ocean floor without his breathing apparatus on"

"Commenting on what might have happened, Mr Culwick said his opinion, given Mr Ring's "confusion" on the surface and his inability to clip his equipment on, was that he had a "significant medical event or succumbed to carbon dioxide poisoning"


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


I've know about rebreathers since I started my technical dive training. However, in my opinion, most divers are not ready to use them. To give an analogy, most fighter jets can out perform the pilot. Human physiology is such that our physical and mental limitation result in too many stressors are placed on the mind and body.

I believe the technology is fantastic, however, people make mistakes. One of the biggest mistakes a diver can make is diving beyond the scope of their training. While a preponderance of rebreather divers are trained on the machine they use, any deviation from the way it should be used can result in injury or death. 

For me, having a machine that requires that much work seems contrary to the benefits of using one. My deepest dive on the USS Monitor to 241fsw was on open circuit. While there were divers that completed their dives on closed circuit systems, the initial costs, training, ongoing utilization, and maintenance just seem to be greater than the benefit a rebreather could really benefit me for the amount of deep water dives with extended decompression obligations.

The abstract below claims that rebreather deaths may be as high as 1 in 100 users. 1% is a crazy high number. Recreational scuba diver deaths are far, far lower. 

"Rebreather deaths occurred at about 10 times the rate of deaths amongst open-circuit recreational scuba divers."

"Closed-circuit rebreathers have a 25-fold increased risk of component failure compared to a manifolded twin-cylinder open-circuit system."

Analysis of recreational closed-circuit rebreather deaths 1998-2010.

Abstract

INTRODUCTION:
Since the introduction of recreational closed-circuit rebreathers (CCRs) in 1998, there have been many recorded deaths. Rebreather deaths have been quoted to be as high as 1 in 100 users.

METHODS:
Rebreather fatalities between 1998 and 2010 were extracted from the Deeplife rebreather mortality database, and inaccuracies were corrected where known. Rebreather absolute numbers were derived from industry discussions and training agency statistics. Relative numbers and brands were extracted from the Rebreather World website database and a Dutch rebreather survey. Mortality was compared with data from other databases. A fault-tree analysis of rebreathers was compared to that of open-circuit scuba of various configurations. Finally, a risk analysis was applied to the mortality database.

RESULTS:
The 181 recorded recreational rebreather deaths occurred at about 10 times the rate of deaths amongst open-circuit recreational scuba divers. No particular brand or type of rebreather was over-represented. Closed-circuit rebreathers have a 25-fold increased risk of component failure compared to a manifolded twin-cylinder open-circuit system. This risk can be offset by carrying a redundant 'bailout' system. Two-thirds of fatal dives were associated with a high-risk dive or high-risk behaviour. There are multiple points in the human-machine interface (HMI) during the use of rebreathers that can result in errors that may lead to a fatality.

CONCLUSIONS:
While rebreathers have an intrinsically higher risk of mechanical failure as a result of their complexity, this can be offset by good design incorporating redundancy and by carrying adequate 'bailout' or alternative gas sources for decompression in the event of a failure. Designs that minimize the chances of HMI errors and training that highlights this area may help to minimize fatalities.

https://en.wikipedia.org/wiki/Scuba_diving_fatalities

Fatality rates of 16.4 deaths per 100,000 persons per year among DAN America members and 14.4 deaths per 100,000 persons per year the British Sub-Aqua Club (BSAC) members were similar and did not change during 2000-2006. This is comparable with jogging (13 deaths per 100,000 persons per year) and motor vehicle accidents (16 deaths per 100,000 persons per year), and within the range where reduction is desirable by Health and Safety Executive (HSE) criteria,[3]

Data for 17 million student-diver certifications during 63 million student dives over a 20-year period from 1989-2008 show a mean per capita death rate of 1.7 deaths per 100,000 student divers per year. This was lower than for insured DAN members during 2000-2006 at 16.4 deaths per 100,000 DAN members per year, but fatality rate per dive is a better measure of exposure risk, A mean annual fatality rate of 0.48 deaths per 100,000 student dives per year and 0.54 deaths per 100,000 BSAC dives per year and 1.03 deaths per 100,000 non-BSAC dives per year during 2007. The total size of the diving population is important for determining overall fatality rates, and the population estimates from the 1990s of several million U.S. divers need to be updated.[3]

A review of my video, "Jerry Seinfeld says, "who aaaaaarrrre these people?"



A review of my video, "Jerry Seinfeld says, "who aaaaaarrrre these people?" How did they become scuba certified?" (original video)

https://youtu.be/TZJE1fuGrHg

#scuba #cavediverharry #whoarethesepeople #scubadiving #padi

I created this video on January 24, 2017 because there are some divers out there that have been trained poorly. It seems that every other video show divers that are freaked out, destroying the dive site, or nearly kill themselves. For the longest time, there was very little traffic on this video, then, out of nowhere on April 28, 2017, I got 211 views in one day! Suffice it to say, someone must have told someone and the word spread. As of today, I have 562 views.

My video illustrated these things:

1) Two divers on the ocean floor and creating a cloud of silt
2) A diver kneeling on the ocean floor and another that looks like they are walking
3) A silt cloud so large that you can barely make out the divers
4) A diver is a lot deeper than the others while only two divers are close enough to each other to help each other if needed
5) A diver is having to go vertical to clear their mask
6) It looks like the diver is at about a 45 degree angle and bicycling their kicks
7) A diver is using their arms to propel themselves
8) A diver bicycling during their kicking
9) A diver alone and on top of a huge patch of kelp
10) A diver's octo is hanging off their side and everyone in the picture is vertical
11) Two divers vertical in the water and standing on the ocean floor
12) Vertical divers
13) This diver is vertical and arms and legs stretched out like they just scored a touchdown!
14) All the divers in the picture are kneeling on the bottom while video recording
15) Divers kicking up silt and all of them dragging their fins across the ocean floor, one of them looks like actually dragging their fins on a structure
16) Three divers on the ocean floor, two kneeling, one in the "fin pivot" position
17) Three divers in the scene, everyone too far away from each other, and one diver is turned on their side
18) I found a video with the title, "PADI ADVANCED OPEN WATER CHECK OUT DIVE JULY 3-4, 2016" when I did a search for, "scuba padi advanced divers." It was published on 7/17/2016 and says they completed, "deep, night, drift, wreck, peak performance buoyancy, and navigation"
19) From the "Advanced Dives in #18 (above): Navigation, vertical in the water and looking down on the compass; A diver has a nudibranch in their bare hands; Three divers vertical in the water; Three divers in the background vertical in the water while the diver in the foreground has their left hand on their primary 2nd stage; A diver is on their side with one leg stretched out like they falling down...

About a month after I made this video, I was thinking, "Who were these diver's instructors?" During their training, I suspect that their instructors were thinking some crazy things to themselves, so I made a video titled, "Top 10 Things You Never Hear the Instructor Say OUT LOUD..."

https://youtu.be/_SAyx6oGuJU

Yesterday, I found a blog post from Cave Diver Harry in November of 2013, "10 Ways to Tell Your Students Are Not Ready for Open Water" that talked about this vary same thing! He even has his own video in the blog. Here is what his list is comprised of:

1) They can't clear a mask without significant stress
2) They can't do a proper kick
3) They think 20 pounds is okay with a 3 mm suit
4) They go vertical as soon as they stop swimming
5) They think it's okay not to clip off octopuses and consoles
6) and 7) They think it's okay to stand, sit, or kneel on the bottom
8) They can't get neutral without doing a "fin pivot"
9) They can only hover while sitting like a Buddha
10) Buoyancy Control Turtle disapproves of their flailing

My response to the TDI blog, "Teaching Scuba Diving Myths"

https://www.tdisdi.com/teaching-scuba-myths/

Wonderful guys! Yes, buoyancy is TOTALLY doable at open waterl as is drysuit. The funniest part of that is that PADI teaches this thing called “fin pivots.” That exercise is not suppose to stop after they bob up and down for a couple minute… from that point, lift your legs bend your knees and start moving forward! Keep breathing, too. The scariest thing I’ve ever seen are divers standing up while they do their skills. Yes! They are REALLY standing up.

After buoyancy skills come finning techniques. I only propel myself with the modified frog kick, but will settle for frog kick from my students. I’ll give them a little wiggle room and a little flutter kick here and there in mid-water, but the flutter kick is notorious for destroying the environment. Partnered with finning techniques comes those buoyancy skills. Less kicking, more buoyancy, and everything falls into place — better air consumption, better situational awareness, and longer bottom times.

There is an instructor in the country somewhere that teaches frog kick from snorkeling and nobody gets into scuba gear until they are using it.

NO, NO, NO…!!! If the student says they are uncomfortable, they are not ready to be certified! The diver MUST be confident because once I sign off on their training, they must be autonomous. That only means one thing. If they are not going to pay me to join them on their dive trips to all the exotic locales, they are 100% ready to dive without me. Students can’t be freaked out by doing an 85-95ft dive in the Puget Sound in the exact same conditions from which they were trained just because the next set of dives are going to be in warm clear water. SDI, SSI, GUE, NAUI, and BSAC award open water divers 100ft access so if they can’t do a 100ft dive in the Puget Sound after certification, they need more dives. Any instructor awarding cert cards to divers that are freaked out will eventually have their butts served to them in court.

Regrettably, PADI fails to inform their students that they only get 60ft, and in conditions from which they learned. If they learned in the Puget Sound, 60ft in Mexico and Hawaii is appropriate. If they learned in Fiji or Tahiti, then they should take PNW dives very cautiously. Also, divers with PADI Advanced Certifications can only cautiously approach 100ft without an actual “Deep Diver” certification. Dive operators sometimes fail to hold these new divers to those standards because their c-card says “advanced.”

I’ll address the e-learning lastly, but my perspective is contrary to the way I know it is often used. I don’t mind students using it, but every student gets a full educational review with me so that I know what they absorbed. I can tell within the first few questions I asked of them if they blew through it. My educational review is designed to take what they learned on their own and give them the tools to take what I give them to the open water — life lessons from an experienced diver and instructor. I approach most of the questions open-ended. In fact, my final exam is fill-in-the-blank. I won’t dive with another that got 10-20% of their final exam wrong. Academics are completed before pool; pool prior to open water; and only then open water.

In the end, my standards are high because it’s easy to kill oneself diving and I won’t be responsible for that! I encourage other instructors out there to set their standards above and beyond what’s in your standards and procedures manuals. Your students deserve it, the industry need it, and good training should never be the exception.

PADI | HLSD | 20 Performance required skills for PADI Open Water | REVIEW and EVALUATION

PADI
HLSD
20 Performance required skills for PADI Open Water


Like all certification agencies, performing the necessary skills in order to pass the course is important. Yet, minimizing the scope of all the skills really required means that divers get in the water, have mechanical failures, don't know how to deal with them, and believes that resolution of the problem equates to getting to the surface.

Getting to the surface is the last step of a safe ascent. Stop, breathe, think, and act is something that should be part of every certification agency's training standards. The dumbing down of skills is very worrisome.



...did not check hydro date; did not check visual date; did not check o-ring; did not check functionality of pressure gauge through purging of regs from full to empty; did not check for leak between 1st stage and tank valve under pressure; did not breath on alternate 2nd stage; did not check primary 2nd stage and alternate 2nd stage for holes in diaphragms (sealed on inhalation under no pressure); did not check inflator for functionality (starting and stopping); did not check BCD for leaks (holding air by squeezing BCD).


Ready for buddy check...


PADI calls their buddy check, “BWRAF,” where it looks like they run their arm downward, pulls, grabs, points, and pats around the diver...







...diver then breaths on his alternate while 30lbs+ of gear is on his back. A buddy check should include a full removal of the equipment as if one was in an emergency situation. It should not be necessary to it before every dive, but familiarization with the removal is not something that should wait for a "Rescue Diver Course." Buddy checks start with the assembly of gear.

Each in the buddy team should be watching and listening for proper assembly. Waiting until the diver has completed the assembly often results in only one person making sure of proper assembly instead of two or the group. How do two or more people result in a failure in equipment assembly? That is not a buddy check...



...the other points to his manual deflate button. ...the spins the diver around and they both give the “okay” sign.

Where is the diver's weight belt? Isn't the buddy going to confirm that it is donned properly with a right hand release?



Diver is ready to do a deep-water entry and already has his fins on. Did he have help doing this? Did he use the figure-four technique? How did he don them?


Notice that the diver immediately puts his hand to his head to sign that he is “okay." He didn't confirm that he is staying on the surface, that he has not lost his mask, or that he has not lost his weight belt (weights)...

By immediately giving the okay signal upon coming to the surface, the person watching the entry turns around starts helping another. Do not give the okay until you are sure your are okay which also means that the person watching the entry is available to help if necessary!


...this is where he is doing his weight check. Is this a weight integrated BCD? If so, the buddy check didn't include how to ditch integrated weights. Weights (in their entirety) should not go in non-ditchable pockets.

Notice that you can see the diver's alternate 2nd stage keeper is not attached to his alternate. So... where is it?


...there it is. NOT attached to the keeper while he is switching between his snorkel and primary 2nd stage. If his primary 2nd stage fails, he loses it, or is unavailable, the diver will have to search for the alternate which he is assuming it is connected at the keeper's location, but it will NOT be.

Choosing a reg keeper that fails to keep the reg attached should be tossed. Find and use ones that keep the reg where you put it!


...the diver is demonstrating switching between the snorkel and his primary 2nd stage underwater. While he is demonstrating regulator removal, regulator replacement, and regulator clearing techniques, doing so while one is moving through the water puts the student at risk.

I teach, outside of demonstration of techniques, NEVER take the regulator out of your mouth until you are sure you have reached positive buoyancy on the surface. If for any reason the diver dropped below the surface, no water goes into the diver's mouth and can precipitate aspirating water. It also looks like the diver is not fully on the surface to be using his snorkel. His legs and feet are way to low to be “snorkeling.”


I saw the diver equalize on the surface using the Valsalva Technique or the Toynbe Maneuver. If he was continuing to equalize on his decent using the Frenzel Maneuver, he should have pointed to his nose to demonstrate to the student to continue to equalize. Even in the shallow side of a pool, damage to the tympanic membrane can still occur. I can feel pressure as soon as I kneel down, and this diver descended to the bottom of the pool from the surface!



The diver's “lean and sweep” is done very poorly. His head is leaning, but his body is leaning very little. The gap created is so small that his hand almost doesn't fit between his body and the low pressure hose. His arm and hand stop prematurely, too. It stops so far to the right...



The slide states that they will be out of air and then “buddy breathe.” The diver raises his arms and lets the other diver get the regulator on his own!

There is no control nor defense in the event of panic. The alternate should be donated and put in front of the face of recipient so that the only thing is visible is the regulator. If the recipient cannot see anything other than the donated reg, there is more control and doesn't put two divers at risk.

Additionally, this is NOT, “buddy breathing.” It is out of air and air sharing from an alternate. Buddy breathing is one reg between two divers! If the instructors use the wrong terminology, how can the students expect to do the right thing.


They are doing an air sharing ascent. The recipient does not have the low pressure inflator system in his hand to deflate or slow himself on the way to the surface.

Additionally, he has a hand on the reg which looks like he is preventing it from being taken out of his mouth. One hand from each diver is enough to make sure they don't get separated. When he gets to the surface, he will have to find the low pressure inflator in order to orally inflate the BCD.

Since the donor has air in his tank and is letting air out of the BCD (because it is in his hand), it is possible that the donor could get to the surface and stay there and the recipient could fall away and drop back below the surface if he is let go of...


Breathing from a free-flowing regulator is easy. Why don't they teach a buddy team how to resolve the issue and stop it? If that procedure doesn't work, the diver will only be able to breathe on a free-flowing regulator for about 30 seconds if the cylinder only has 500psi in it... a full tank can empty in less than 5 minutes.

Cold air and cold water are the primary concerns. Cold water techniques MUST be taught if diving in a cold water and cold air environments. This is not an advanced specialty.



Fin pivots mean that the diver has fins on the bottom of the pool while practicing buoyancy techniques. A preferred method is to get off the bottom entirely and focus on something on the wall of the pool and be able to emphasize neutral buoyancy with breath control alone...


More acronyms? Using acronyms are the best way to have someone to skip part of the process altogether or even fill in other techniques that are not part of the process.


Diver IS wearing a weight pocket style weight belt... was not part of the buddy check. Proper weighting, explanation of weight placement, and ditching weight has to be done before being near any body of water.


Floating vertically is easy. All the air is at the top of the BCD. All of the diver's weight is below them. This is NOT a natural position for a diver. Teach diving position from the beginning.


The last techniques were remove and replace weights on the bottom and surface and remove and replace the BCD on the bottom and surface...

While there are aspects of each that have their merit and the pool is a great place to practice these skills, in the open water, doing these skills may have unforeseen consequences. The need to ditch ones weight, therefore easy access and understanding how of to do it, is important.

Similarly, removing life support equipment, namely the BCD with the attached tank and regulators has incredible risk. A technical diver would never remove their equipment and as the best trained divers in the industry, keeping your gear on has a valid reason. If one is on the surface and entangled, one can ditch their weights first and use a cutting tool to free oneself.
