• Suitable for coldwater use
• Compatible with EAN40 out of the box

First Stage:

• 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 rate faster than ambient. This results in superior performance at depth.
• 2 HP ports and 4 MP ports are angled for optimum hose routing
• An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out

Second Stage:

• Pneumatically-balanced second stage results in smooth, easy breathing
• A 2-stage progressive purge is used. Press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the center for the full effect of the purge, i.e. when regulator clearing etc.
• A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water

Octopus:

• It provides the same features and performance as the XTX50 second stage and includes left / right hand reversibility.

• 5000psi Pressure Gauge
• 230ft Depth Gauge
• Compass with Ratchet Bevel and Side Viewports
• Luminous Faces
