He has a ScubraPro MK20/G250 with a console or a Genesis GR450/GS2000 with a console.
Both of them have psi/computer/compass.
The Genesis is brand new and the Scubapro is the one he was using for an extra. Until I started using it.
So, I can have whichever one I want but I don't know if new is necessarily better.
Which one would you use if you were just starting out?
No brainer, the SP. Not even close. Avoid the genesis reg, it has this bizarre depth compensating valve-driven dry ambient chamber added on to a sherwood-style flow-by piston. The result is that it lacks the reliable simplicity of the sherwood design while also sacrificing the air flow performance of a flow through piston like the MK20. The G250 2nd stage, assuming it's not G250HP, is one the most successful and copied 2nd stage designs in history. A real classic.
