Apeks Pack XL4 OCEA + Octo

First Stage
• Compact machined first stage based on the expedition-tested Apeks DS4 platform.
• Break through, innovative over-moulded first-stage endcap and environmental diaphragm help prevent ice build-up that can cause first-stage free-flow in extreme circumstances. Also protects the first stage from impact damage.
• Large surface area heat exchanger diaphragm clamp helps increase the gas temperature inside the first stage, resulting in improved cold water performance.
• Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows the medium-pressure gas in the hose to increase faster than ambient pressure, resulting in superior performance at depth.
• Equipped with 2 high-pressure ports and 4 medium-pressure ports.

Second Stage
• Compact and lightweight second stage improves comfort and helps reduce jaw fatigue on long-duration dives.
• Large heat exchanger to improve cold water performance and freezing resistance. 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 traditional rubber hose.
• Standard metallic hose connection allows interchangeability.
• Comfo-bite mouthpiece features a unique bridge across the upper palate and does not require bite pressure to stay in place.
• Reusable mouthpiece clip makes it easy to change mouthpieces in the field.
• Durable and flexible rubber exhaust tee provides excellent bubble diversion.
• UV inhibitors help prevent discoloration of white materials.
