How do you compensate for the weight of air in your full tank if you don't need to add any air in your BC at the beginning of the dive?Thanks for all the responses. So it seems that pressing the purge button on the inflator hose when the BC is empty will cause water to flow in? That makes sense and I'm pretty sure that explains the constant filling up of my wife's BC.
We both try to weight ourselves such that we require no air in the BC during the dive. We might add some air at depth just to fine tune our buoyancy on the reef but we typically dump everything as we start making our ascent. I suspect this is where she basically just hold the button down too long in her effort to make sure that all the air is purged.
I'll mention to her to try use the kidney dump valve next time to see if that makes a difference.
Thanks again.
