- Recycled polymers made from up to 70% post consumer waste (black components)
- Bioplastic plastic parts made from non petroleum based sources.
- Trivalent chrome plating uses less harmful chemicals and is kinder to the environment.
- Eco brass is lead free, easier to recycle and has a higher tensile strength than traditional brass.
Apeks XL4 Ocea First Stage
- Compact machined first stage based on the expedition tested Apeks DS4 platform.
- Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.
- With 2 HP ports and 4MP ports.
Apeks XL4 Ocea Second Stage & Octopus
- Compact and lightweight second stage improves comfort and helps reduce jaw fatigue on long duration dives.
- High performance pneumatically balanced lever operated poppet valve.
- Large, over moulded self-flushing and controllable purge button.
- Ergonomic Venturi lever is easy to use and locate.
- Flexible nylon braided hose has better cold water performance than a traditional rubber hose.
- Standard metallic hose connection for interchangeability.
- Comfo-bite mouthpiece has a unique bridge that fits across the upper palate and does not require bite pressure to stay in place.
- Re-useable mouthpiece clip makes it simple to change mouthpieces in the field.
- Durable and flexible rubber exhaust tee provides excellent bubble diversion.
