Re: Octopus, or no Octopus?
I never breath my tanks to empty! True I keep shallow usually 20ft or less. Aluminum tanks change bouyancy drastically which helps give a sense of fill. Also the sound of the air expanding out the first stage changes pitch at different pressures. That last 150psi or so has a distinctive moisture taste if you really push your dive.
Low profile is the way to go. Especially in the kelp forests of the west coast here, too much to get tangled up in.
