The XTRA 2nd stage is a balanced adjustable second stage in a rugged low-weight body featuring metal internal components with increased resistance to freezing when diving in extreme conditions. The large diaphragm and exhaust valve provide responsive inhalation and easy exhalation in all positions. An adjustable inhalation effort knob sets the cracking resistance to your preference and the dive/pre-dive switch minimizes free flow in when used as a backup. The XTRA also includes a long bite orthodontic mouthpiece to reduce jaw fatigue, and the SeaCure #4 mouthpiece will also work.

Our recommended service interval is every two years or one hundred dives. There is nothing unique about the DGX regulators in terms of service requirements and needs no special tools beyond those generic tools found on the typical regulator technicians bench. We sell the DGX Gears XTRA service parts kits direct to the public.
