Product Description


Apeks XTX50 Regulator Plus XTX20 Octopus, Stage 3

Limited offer with Free Octopus 

Be it from a shore, a RIB or hard boat these XTX50 regulators from Apeks are built strong to stand up to the harshest diving conditions.. From styling to internal and external build quality XTX regulators from Apeks are packed with features such as subtle chrome accenting to reversible hose routing. Apeks XTX regulators are designed to be as flexible as you are. The XTX20 octopus is built for use in water warmer than 10⁰C but keeps the same robustness and reliabilty as the rest of the XTX range. Lightweight and compact the XTX20 octopus is an excellent addition to the XTX50 stage 3 regulator set for demanding use in warmer climates.

Reversible Second Stage Valve Operation

All XTX regulators have reversible valve operation, allowing a service technician to route the hose from either the right or left hand side of the regulator. This greatly improves hose routing options, allowing a diver to more comfortably configure their regulator setup.

XTX Reversible Venturi System

The reversible venturi system allows a diver to control the flow of gas through the regulator to improve freeflow resistance and breathing effort. The indexable venturi lever can act as a pre-dive switch, in the minus position the regulator will not freeflow when dropped into water or the entry phase of the dive. In the plus position the Venturi Assist improves breathing assistance. Due to the design of the Venuri Assist System it can be placed in the correct position depending on which side the hose is configured.

Diver Changeable Exhaust System

The Diver Changeable Exhaust (DCE) System allows the diver to choose between two exhaust tee's to make the second stage either more compact or to provide better dispersal of bubbles on exhalation. The larger exhaust reduces bubbles from entering a divers field of view whilst the smaller tee piece reduces the bulk of the second stage whilst reducing weight.

Pnuematically Balanced with Cracking Resistance Control

Pneumatically balanced design means that inhalation effort is reduced providing a more comfortable breath over long periods of time. Cracking resistance can be controlled to provide the perfect amount of breathing resistance and to reduce freeflows. An internal fine adjustment can be adjusted by an Apeks Service Technician to set the regulator up for minimal breathing resistance through a range of medium stage pressures.
