This package pairs a primary regulator with the Oceanic Alpha 8 Octopus, so you leave with a complete first-stage-to-backup setup in one purchase. Choose your primary regulator on the product page from three Oceanic options: the Delta 5 + EDX, the ZEO FDX-I, or the Alpha 8 + SP5, and it’s bundled with the Alpha 8 Octopus as your backup second stage.
The Delta 5 + EDX Dive Regulator Set (shown as the default selection) builds on Oceanic’s Delta lineage with a balanced diaphragm first stage, the EDX, that’s environmentally sealed and cold-water ready, plus a pneumatically balanced all-metal valve at the second stage. A dive/pre-dive switch and dynamic airflow adjustment control let you dial in breathing resistance, a heat exchanger helps in cold water, and the dual-material orthodontic mouthpiece with bite tabs is built for comfort on longer dives. It’s Nitrox compatible to 40%, the second stage comes in Black or White, and Oceanic backs it with a lifetime warranty and free parts for life, plus a 2-year required service interval.
The Oceanic Alpha 8 Octopus rounds out the set as your backup air source. It runs its own demand valve with a balancing system and integrated purge button, uses an orthodontic mouthpiece for comfort, and is Nitrox compatible to 40% as well. At 6 ounces without the hose and a 2.9-inch front profile, it’s built to stay out of the way until you need it, and it’s designed to perform to U.S. Navy Class A standards at 198 feet. It carries a limited lifetime warranty with a service agreement, and both pieces come with Oceanic’s 30-day satisfaction guarantee.
