I wasn't sure if I should post this in the "tek" area since the topic is backplates but with so many related questions in this forum I figured this is a good spot.
Thanks to all of you who continue to put up with all my newbie questions but now I have another one.
As I understand it, the difference in buoyancy of a full vs. empty 80cf Aluminum tank is ~6 lbs., also the weight of most stainless steel backplates. This would just offset the air used up, leaving the stuff on your back just a little negative.
Even if you were diving in your birthday suit (apparently people actually do this!) and were minimally buoyant (i.e. no wetsuit) would you ever want to use an aluminum backplate? Wouldn't using one just mean more weight on your belt in order to stay a little negative at your end-of-dive safety stop?
I'm still trying to think through the ins and outs of weighting and buoyancy; thanks again for indulging (and educating!) me.
