1. I’d be willing to bet you are carrying too much lead.
2. Air moving from one side of the BC to the other will not affect buoyancy.

Use the weight calculator on this website to get starting point for how much weight you need.


When you’re done practicing, run the tank to 500 psi (at the surface, bleed the air out by pushing the button on the second stage) and start removing weight a little at a time and try to descend after each time you take a little weight out. Now practice on a second tank with that amount of weight. From there on, every time you dive, write in your log book what equipment you used, how much lead you used, and if it was too much or not enough or just right.
