We tested the Oceanic Delta 5 regulator. With top scores in its category for dry, easy breathing, it was our Testers Choice for regulators under $600.

We tested the Delta 5’s ability to deliver air at range of depths and breathing rates on a breathing simulator at Dive Lab in Panama City Beach, Fla. We also tested the Delta 5 at Alexander Springs in Central Florida with a team of test divers who scored it in 14 categories including ease of breathing, dry operation and comfort.

This latest in the long line of Delta regs has a very refined new look (yes, it’s also available in black). More importantly, it has performance to match. Both the eDX diaphragm first stage and the second stage are equipped with ribbed heat exchangers for improved performance in cold water, and the second stage now has an all-metal valve. On the simulator, the Delta 5’s work of breathing scores were rated excellent across the board. Test divers gave it very good scores for ease of breathing and dry operation in all positions (although some noted it required more effort when face-up) and gave it excellent scores for its predictable, efficient purge and its precise breathing adjustment. Taking top scores and more selections as the favorite of test divers than any other reg in its category, the Delta 5 is our Testers any other reg in its category, the Delta 5 is our Testers Choice for regs under $600.
