I don't recommend doing that - if you accidentally turn the second stage in the fitting while it is pressurized, then the little O-ring in there will get sliced, rendering that reg pretty much useless. If you are going to swap a second, then it's better to keep it tight and carry a small adjustable wrench to loosen it. Just make sure you shut it down and purge it before unscrewing the fitting.this is very interesting to me i hand tighten my sec. stage hose out of habit but have never had to change anything on a dive.
Some other good points were raised in this thread:
1. Make sure all stage/deco regs are interchangeable
2. A piston reg will survive a "hot swap" much better than a diaphragm reg
3. Feathering the valve is an option if you can't swap (for argon reg, etc)
4. Make sure you have a contingency plan for lost deco gas
Did I miss anything?
