Hi Sanso, thanks for the answer. The question is a little random I guess. It's to obtain a benchmark. I dive to 12 M comfortably on 2 EQ's (in addition to the surface pre-EQ). I wanted to compare. Watching one of my buddies I see he EQ's 2 to get to 16M. He is very experienced. So, let me ask you: to 12M how many EQ's do you need (not how many do you do?)
When line diving I do many EQ's, even too many (force, work etc resulting in more O2 use). But spearing I do very few, because my hands are occupied (torch, gun, line) and some fish bolt on hearing a hearty Freznel!
