Prior to this morning's quick pool session at a friend's place, I plugged in all numbers in the Optimal Buoyancy calculator spreadsheet and it recommended zero additional lead.
I jumped in the pool this morning to check my buoyancy with all my gear. With zero lead and holding my breath, I sunk just below the surface of the water. The top of my head was prob a few inches to a foot below the surface if I had to guess. Mind you the AL80 tank had about 2500 psi (172 bar) in it. On exhalation I became negative and slowly went to the bottom.
I'm trying to figure out if I should get a lighter backplate in this situation or leave it as is. The backplate I currently have is a Dive Rite stainless XT and is quoted to weigh at 5.5 lbs (2.5 kg). Your thoughts?
