PART 4
TANK AND WEIGHT PLACEMENT

I've found that placing a tank's valve in the area directly behind the shoulders and in the spot where the curvature of the neck would be seems to be the best for most divers.

Even when diving with longer tanks the majority of tank weight and the chest of the diver keeps their center of gravity near the waist when the weights are located above the hip bones.

I've heard divers instructed to keep weights below the top of hip bones which often results in the diver being in a vertical position throughout the dive.



PART 5
PONY BOTTLES, BAILOUT BOTTLES, AND DECO BOTTLES

NAUI strongly encourages divers to dive with buddies.

As the old saying goes "diving with a buddy in the same ocean but too far away to help is not how buddy teams work."

One of the lessons I teach students early on is about redundancy.

Redundancy is different from backup as redundant breathing systems (RBS) are wholly separate from any piece of equipment attached to the diver.

To that extent an RBS can be handed off to another for use.

One of the issues I have with an RBS is that the diver rarely if ever practices with it.
