Hi, I am terribly sorry in advance if this is a silly question, but I just can't wrap my head around it.
According to my PADI book, properly weighted means: " When weighted properly and holding a normal breath, you should float at eye level. " . That's it. They don't talk about adding more weight afterward to compensate for consumed air, etc.
Right, so say I'm diving wearing just a rashguard and short, in the tropics, with an AL80, an ALU backplate and that as a human being I'm born neutral. So I go in the water, with my weights and all, and I take my 'normal breath', hold it, and I float at eye level. So I'm theoretically all good. But now I want to dive. So I exhale, exhale, I'm 2 meters down and I have nothing left to exhale (ex smoker here ), so it's uncomfortable, so I breath in, and at that point surely I at best become neutral, at worst come back up because I inhaled 'too much'.
What I don't get, is that my BCD is empty, I'm not wearing a wetsuit, so there's nothing to compress and reduce buoyancy apart from controlling my breathing.
Surely it should say 'take a FULL breath', make sure you're eye level, THEN add 2kg to compensate for lost air. But then in that case surely in order to float at surface I'll need to inflate my BCD. Which renders the point about the breath moot.
Grrr I'm so confused
