The Envoy II is an incredible value, meeting or exceeding the performance of regulators that cost much more. 

Envoy II is an economical regulator that doesn’t compromise on performance or reliability. Its lightweight first stage, with balanced diaphragm, Yoke, and its 2nd stage has a downstream valve and Dive/Pre-dive Venturi control (with 30″ hose length).

Light and comfortable, the Envoy II Second Stage is compact enough to use as a backup but robust enough to rely on as your primary go-to regulator.
