The Apeks XTX50 Octopus regulator is Apeks's top-of-the-line Octopus in terms of features and performance. It provides the same features and performance as the XTX50 second stage and includes left/right-hand reversibility. It comes with a high visibility yellow front cover and a 36” yellow hose. Suitable for cold water use (below 10 C / 50 F).

The XTX50 Octopus has a breathing effort control knob. This allows the diver to desensitize the unit when it is not being used.

The XTX purge buttons are large and easy to operate. 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 the regulator clearing, etc.

Can be converted from a right-handed hose configuration to a left-handed one. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must ONLY be performed by an APEKS Authorised Service Technician.

Braided flexible hoses are now standard on all models. These hoses are lighter weight, more flexible, and more durable.

Suitable for coldwater use.

Compatible with EAN40 out of the box.

Pneumatically-balanced second stage results in smooth, easy breathing.

The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation.

Manufactured with active protection against infection as all molded parts are produced with an additive that kills MRSA, protects against E-Coli, bacteria, and fungi, and is also very effective against viruses, mold, yeast, and algae.

A silicone exhaust valve improves the breathing performance of the regulator.

The Comfo-bite™ mouthpiece virtually eliminates jaw fatigue.
