– UTD TECHNIQUES – WHY NOT OVERWEIGHTED 1. A properly weighted diver will have an empty BC at the shallow, 10’/3m stop. 2. An overweighted diver must carry that extra weight in the BC at the shallow, 10’/3m stop. 4. An overweighted diver has a lot of gas in the BC that will expand and compress during small variances in buoyancy, making it hard to adjust using the lungs. 3. A properly weighted diver with an empty BC at the shallow stops will have very little gas expanding and compressing during small buoyancy excursions, making it much easier to control buoyancy using just the lungs. 5. Try it in a shallow pool –   control your buoyancy while properly weighted (tank at 500psi/35b). Hover for five minutes. Then pick up a 6lb/3kg weight, inflating the BC to compensate, and try again. Then do it with 12lbs/6kg. See which of those three times is easiest.
