What I mean is it got me into the mindset of paying attention to multiple valves. Ya it doesnt help with the manifold, but I learned how to shut down a dead reg. By dabbling- I was reffering more to the bottom times than anything else. It's not a strong point at all, just an opinion I have. The dive objectives I have are putting me a touch into deco, and I have no real need for 300 cft of gas on my back at this time. I may use the H valves for my cave 1 class this month too. Still struggling with opinions on that.
I used my H valves for Advanced Nitrox/Intro class.
Thanks for not taking offense. Good luck with the cave class! I hear its awesome.
