The Cave Diving Website


Students who do well in Cave Diver training typically practice and master the buoyancy skills outlined on this page, in confined or open water, within 30 days of the start of the course.

Weighting: Using standard recreational diving equipment, prospective Cave Diver students should be able to weight themselves so that, at the end of a dive, with 500 to 1,000 psi in their tanks, they can hover motionless at safety-stop depth, with no air in their BCs.


Body Position: Students should also be able to position themselves, by shifting tank and weight system height, so that they can achieve a perfectly horizontal hover. Students can test this by seeing if they can view everything that is going on behind them simply by tucking their chins to their chests.

Helicopter Turn

Helicopter Turn: While in the position just described, students should be able to complete a 360-degree turn, simply by sculling with their ankles and fins. The rest of the body, including and especially the hands, should remain motionless throughout the turn.
