I have been reading through my copy of "The New Science of Skin and Scuba Diving" and nowhere does it mention trim. It does mention 6" or 7" of breathing effort and that is clearly apparent in my pool sessions.
As 6" or 7" of cracking pressure FAR exceeds any modern single hose regulator, is it common to swim in a somewhat heads-up position to overcome this?
Or, is it simply a matter of "suck it up!" (pun intended)?
I don't really like the 'absolutely flat in the water' trim anyway. Among other things, I can't raise my head far enough to see things out in front of me. In thinking about my previous diving with a jacket BCD prior to my BP/W, I believe I was almost always in somewhat of a heads-up position.
Second item: I understand that with my conventional tank and single hose reg, I should be able to reach the valve. Well, I can't. But it's even worse with the DH rig because the tank is so much farther down the back and the valve handle is behind the can. Any thoughts on this? I had the idea that if I did have to reach the valve (or J valve), I would just loosen the straps and swing the tank around. After all, those quick release buckles come apart pretty fast.
Can anyone reach their valves?
