It was so welldesigned that the same basic seat (with more modern surface material) is usedin every modern Aqualung diaphragm regulator.

(3) This regulator features two stages, with an upstreambalanced diaphragm first stage. It came with black hoses and a curvedmouthpiece, and the later model ones came with a heavier yoke design for thethen new aluminum 80 cubic foot SCUBA cylinder. Medium difficulty to service,as tuning one is an acquired skill much like tuning a modern balanced highperformance regulator.
