Question on the DIN conversion kits. Once in place, does the regulator support the same higher pressures that DIN would? Or is that rating more applicable to the tank valve itself?
The current Scubapro Universal DIN conversion kit is the same parts used on their DIN models. It is easy to swap back and forth. Since the OP lives in Florida and may dive in the Keys he probably should purchase the yoke version and then grab the DIN kit. It is cheaper in total that way.
Also, while I am a Scubapro fan, the Deep Six and DGX sets are perfectly good regulators and cost effective and possibly easier for us normal folks to get parts kits for. Maybe, so it is said. But you cannot go wrong with Scubapro.
