swap 2nd stages on 2 cousteau regs?

[raviepoo]

I have two aqualung cousteau regs. Both are O2 clean. One of them is environmentally sealed and has a DIN fitting. The other is not / does not. The environmentally sealed one has an Impulse 2nd stage. The other has a micra adjustable 2nd stage. I would like to swap the 2nd stages. (Actually, I would like to take the reg to the LDS and have them swap and tune up for me.) Is there any reason why I can't do this?

The shop should be able to do it for you without problems. You could do it yourself provided the intermediate pressure was the same on both regulators. It's best to let a technician do it.
