Spare Air questions

[Chris H]

I'm going to disagree on this being a good system. I'll also admit that I used one exactly like it for years (I'll sell it to you cheap if we can't convince you to do this a better way ). It is nearly impossble to reach the valve. Clipping the bottle to your left side like I mentioned earlier is far better. John J explained some of the reasons for this in his post below with the most important reason being that I can unclip the stage and give it to anyone who is having a problem and then we aren't limited by hose length or any of that sort of thing.

In any situation, especially solo diving, you MUST be able to reach your valves. I dove a single with an H valve on it last night and it was MUCH more difficult to do valve drills with the H valve than with doubles. It is very dependent on tank position, so I need to be very careful when I attach the tank that I get the height exactly correct so I can reach the valves.
