Just messsing with you Stryker, lol. Great regs, I hope you enjoy them for many years. The "Ferrari" of regulators, my opinion, is the Tekna 2100 series from the lated 70s and early 80s. They were odd, quirky, jumpy at shallow depths, fluttered oddly as well in shallow water but below 20 feet they smooth out. They actually overbreath a bit and this phenomena increases with depth. At 200 plus feet they pump the air to you. Yes, they are odd, small, light and side exhaust, virtually no weight, weird looking parts inside and and basically strange all over I venture few modern regs can put out any more air when breathed hard. I have several of the things, odd again how one day they work beautifully and others they are extra quirky. Sometimes in shallow water I have had the beasts shoot out of my mouth and fly around like a squid in full afterburner---yeah, they are the Ferraris. They went out of buisness, I forget why, a lawsuit I think, but these were never big sellers, most folks could not pardon their shallow water behavoir or other oddities. N
