Details: Over 20 years ago we gave ourselves a challenge to design a rugged and reliable all-purpose regulator that would be at home in cold water or warm and breathe just as good at 30 feet as it did at 130. We called that regulator the Delta, and we still do. The Delta5 is the next step in a long line of remarkably reliable, durable and smoothly breathing regulators to carry that name. Sure, we ve given it an updated look, but that s not all. Like the Delta s before it, the 5 comes standard with our patented Dynamic Adjustment Technology that, once set by the diver, provides consistent airflow at any depth.
