Sale! Add to cart Oceanic Delta 5 EDX $899.00 $760.00 The new Delta 5 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 thats not all. Like the Delta’s before it, the 5 comes standard with our patented Dynamic Adjustment Technology, dive/pre-dive controls and a super comfortable orthodontic mouthpiece. Unlike it’s predessors, the new Delta 5 has an all metal pneumatic valve, providing super smooth breathing performance in any condition. We have also added a heat exchanger, positioned on the hose connection to the 2nd stage, to further increase its already stellar cold water performance. We’ve paired the Delta 5 with the new eDX. This top-of-the-line, 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.
