Questions and Answers for ScubaPro MK25 / G260 Regulator System:
I am considering purchasing a new regulator. looking at scubapro MK25/G260, and Aqualung legend LX, and possibly an Atomic ST1 or Z2X. These are all balanced. I believe one is a piston design and the other a diaphram. What is the major difference in performance and reliability? Also which would be a preferred design to go with.

All of these choices are top of the line. Very hard to choose between them. You will not be disappointed with any one of them.
