The Oceanic Delta 5 Second Stage Dive Regulator is designed for reliable breathing across a range of conditions, from cold-water dives to warm-water dives. Building on the Delta legacy, this regulator aims to perform consistently at shallow and deeper stops, delivering smooth airflow and straightforward service.

Key features include a pneumatically balanced all-metal valve, a dive/pre-dive switch with patented dynamic airflow adjustment control, and a mechanical purge button to maintain stable airflow during purge. It supports Nitrox from standard to 40% and features a balanced diaphragm first stage eDX that is environmentally sealed and cold-water ready, along with a heat exchanger to improve cold-water performance. The design includes ergonomic exhalation venting and a compact 2.5 inch front profile, with a dual-material orthodontic mouthpiece featuring bite tabs for comfort. A 2-year service interval is required, and the regulator is backed by a lifetime warranty with free parts for life, plus a 30-day satisfaction guarantee.
