Umm....last time I checked (and this may be different now) Dive Rite was built in FL, Promate overseas. When you open up a Promate, they vaguely resemble a Sherwood- shimms etc. Now, the second stage being generic, the covers fit, I think, but that doesn't mean too much. As for my experiences, I ended up with a set, they were awful. If they weren't freeflowing they were hard breathing, no matter what we did to them. Had another buddy that ran the same problems. BTW, I never truely used them, just in a pool, way too cappy in my opinion to use in real water.

Jay,
The RG3000 you dive is made in the very same factory and uses the same kits as the Promate Tornado, TDL, Salvo, and Oxycheq regulators.
You have a great set of regs, no doubt , identicle in design to a Promate.
I can only assume when you talk about shims, you are refering to a piston regulator , thats how the intermediate pressure is tuned. No shims in your RG3000 or should I say Ocean Divers Balanced Diaphram Branded Diverite...
I sell and service the Promate regulators and just wanted the brand to get a fair shake.
Thanks,
Gary
