The new Delta 5 EDX is the latest evolution in a long line of remarkably reliable, durable and smoothly breathing regulators to carry that name. It not only looks great, but like the models before it, the Delta 5 comes standard with our patented Dynamic Adjustment Technology, dive/pre-dive controls and a super comfortable orthodontic mouthpiece.We’ve paired the Delta5 with the new eDX. This top-of-the-line cold forged, over-balanced diaphragm first stage is environmentally sealed and comes with 4 low-pressure and 2 high-pressure ports. It also comes equipped with a heat exchanger for added cold water performance.
