I just recently purchased a Neo reg setup. However in the manual it covers the Alpha 7, Gamma, Delta 3, Gamma 2, Omega 2, and Zeta which isn't even made anymore. Is there a new updated manual with the Neo. The question I have about the reg is there is a round flat piece right next to the Venturi switch that rotates. What is that? It turns but I have not a clue what it is? The only feature of the Venturi switch is the dive/predive (+ or -) adj. The reg isn't supposed to have an inhallation knob. If anyone knows what it is it would be appreciated. I would of asked the LDS when I bought but I didn't realize it was there. It doesn't seem to screw in or out.
