Overview
Oxygen compatible materials and lubricants go into this decompression regulator, which pairs an unbalanced piston DIN first stage with an adjustable second stage. An orthodontic long bite mouthpiece reduces jaw fatigue on long deco stops.
Oxygen readiness out of the box and a lightweight setup are the reasons to choose it for staged decompression. The unbalanced first stage limits depth, and hose choice is restricted.
Who it's for
Technical divers staging oxygen for shallow stops will use the pre-assembled green setup with its depth limit in mind. Recreational divers who want a primary regulator, or anyone planning deeper use, should choose a balanced model.
Pros and cons
- Oxygen service ready
- Adjustable second stage
- Long bite mouthpiece
- Mini SPG supplied
- Incompatible with MiFlex HP hoses
- Unbalanced first stage
- Weight figure only in the specs
Performance notes
An unbalanced piston first stage is simple and reliable, but its output pressure changes as tank pressure drops, which is why it is limited to shallow use. The adjustable second stage tunes breathing effort for decompression. The long bite mouthpiece spreads pressure to ease the jaw.
