Description
First Stage
- Breakthrough, 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 1st 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 at a faster rate than ambient. This results in superior performance at depth
- Compact machined 1st stage based on the expedition tested Apeks DS4 platform.
Second Stage
- Compact and lightweight 2nd 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 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.

XL4 Octopus
- This Octopus is based on the XL4 second stage

- Diver adjustable venturi control
- Durable and flexible rubber exhaust tee
- The unit has a high visibility yellow accent pieces and a 36” braided yellow hose
2-Gauge Console
The 2-gauge console combines a submersible pressure (contents) gauge and a depth gauge housed in a specially designed case. The unit is completed with a high pressure hose. The console clearly displays your pressure and depth readings for easy viewing under water and the dials have a long phosphorescent effect for better reading in poor visibility conditions. The submersible pressure gauge provides accurate pressure readings with a range of 5000 psi (metric available up to 360 bar). The depth gauge reads up to 230ft (metric available to 70 m).
- The gauge case is made from nickel plated brass
- The dial window is made of highly shock resistant material (anti-splinter polycarbonate)
- A specially designed housing protects the gauge and HP hose fitting from accidental damage
- A large loop area designed into the housing allows for easy attachment.
- There is an over-pressure capsule fitted in the back of the module to prevent the screen from exploding in the unlikely event of the internal mechanism failing.
- Dials have a long phosphorescent effect for better reading in poor visibility conditions
- There are 2 attachment areas integrated into the design for position flexibility
- This may be a compact design but the displays are vivid and clear – perfect for diving. For example, the depth gauge spreads the first half of the scale and in total shows a range down to 230 feet
- Depth gauge has resettable max depth indicator
- A specific O2 clean version is available for use with high percentage oxygen gases
