    XTX50 Octopus
    $270.00

    Apeks

    XTX50 Octopus

    2 Review(s)

    The XTX50 Octopus is our top-of-the-line octopus in terms of features and performance. It provides the same features and performance as the XTX50 second stage mentioned previously but comes with a high visibility yellow front cover and a 36" yellow hose. The XTX50 Octopus has a breathing effort control knob. This allows the diver to desensitize the unit when it 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 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 Authorized Service Technician. Braided flexi-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. The 2nd stage is 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, mould, yeast and algae. A silicone exhaust valve improves the breathing performance of the regulator The Comfo-bite™ mouthpiece virtually eliminates jaw-fatigue 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 Orientation Convertible LH or RH Coldwater Use Yes Type of second stage Pneumatically balanced Breathing Effort Control Knob Yes Integrated Venturi Lever Yes Mouthpiece Comfo-bite™ Heat Exchanger for freezing resistance Yes Hose type Braided Flexi-hose Nitrox compatible Yes to 40% O2 when new, out of the box / Can be O2 cleaned to100%

    M1 Octo

    4 Review(s)

    The Atomic M1 Octo is built on the same platform as the Ti2 and Z1, the Atomic M1 Octo has some unique features that make it the choice for certain extended range applications. The Atomic M1 Octo is factory rated for oxygen-enriched mixtures up to 80%. The front cover is unique in that there are no openings in front of the cover. This helps prevent the regulator from turning on if subjected to wave surge or strong currents. The demand valve body is Zirconium plated brass for fast thermal transfer with a heat sink feature to reduce the possibility of freezing in cold water. The critical metal components of the demand valve (lever, orifice and spring) are all made of titanium and are completely corrosion proof. Like all Atomic regulators, the Atomic M1 Octo has the AFC automatic flow control, Seat Saving Orifice valve design and manual override knob to reduce regulator sensitivity during entries or exits.

    Ti2 Octo

    1 Review(s)

    The worlds’ first and only back-up second stage featuring all titanium metallic components for the lightest weight and total corrosion resistance. This regulator is immune to the performance degrading effects of seawater corrosion. The patented Atomic Aquatics Seat Saving Orifice prevents wear of the low-pressure seat that extends the service interval and improves reliability. These features result in a safe second that can be counted on to perform like new when you need it. The regulator is compact, with a low profile exhaust deflector that fits easily into pockets and a bright yellow flexible front cover for high visibility. The Ti2 Octo is the same second stage used in the T1 and B2 first and second stage combinations that have received more accolades from the diving press than any other regulator ever built. The only depth activated flow control in the world, the Atomic Aquatics AFC (automatic flow control) automatically adjusts the airflow at depth for natural effortless breathing without having to make external adjustments.
