I am thinking of get back into scuba after a long period of no diving. I bought a Tusa libirator reg. setup in the early 90's ( 90- 92 ) and cant remember the model #'s back then. I would like to ID this reg. setup and get opinions on the performance from anyone who may still be diving with one' or had one back then. I used the Tusa and a Sherwood setup for about five years and had great performance with it. I know it will have to be serviced, and I am almost positive that the parts are still available. Any help would be appreciated.
