Read the description carefully... the direction was NOT to exhale and see if you sink... It was, exhale "slightly" and see if you sink.
I will let someone else look up what volume of air will be expelled when a diver fully exhales (versus) slightly..(a couple of pounds worth, i'm sure). As mentioned above, it should work ok, plus I think most of us are assuming that divrs who need this kind of "hand holding" are most likely diving in warm water with a single 80 cu-ft aluminum tank...
If you are diving with a dry suit and double 120's.. I sure hope you can figure out how much lead you need without too much supervision.
