archman:That TUSA model looks like a virtual clone of the AIR2. I wonder if anything is different other than the name stamped on it. ScubaPro must be pissed to be ripped off so blatantly, unless they've brokered an agreement with TUSA.
Actually Tusa and SP work together on a bunch of products. The Air 2 is one of them. Also, Tusa is picking up the MK16 first stage from SP, and SP has just picked up a bunch of the Tusa masks. Most all these companies share products like that.
To think a single manufacturer would spin brass regs, plastic inject, rubber mold, sew wetsuits and BCs, solder chips... not going to happen. Each come up with their strong points, then they make stuff for each other. This happens all the time. Genesis/Sherwood is picking up the Dacor Tiger Fin, The Tusa Pano Geo mask will soon be available with a Scubapro name, etc...
