Wow, you even start off with the valve off. Funny thing is I can actually see the gauge is down to nothing when you check.![]()
Now are you shutting off the valves every time you switch regs, or is this just in practice for a failure?
Just valve drills . . . I was practicing all the skills while swimming and hovering. I just wish I could remember to turned the danged things back on! :lol:
