MK17/G250 System is the perfect balance of power. Our diaphragm MK17 first stage teamed with our newly designed G250V
second stage.

This exceptional second stage features a 35% improvement in breathing performance when compared to its popular predecessor: the G250HP. It’s a terrific cold water combination.

G250V is a full metal system, composed of ametal inlet tube, stainless steel orifi ce, metal inhalation-resistance control knob, and a metal hose connector/heat exchanger.
Serious construction for serious divers. New VIVA knob for easier Venturi adjustment. High-flow exhaust boat valve to reduce effort.
