PRODUCT DETAILS
Pro-Level Backup. Everyday Simplicity. Citrus-Bright Reassurance.
The Apeks XTX40 Octopus is the kind of backup reg you rig once and rely on forever. Delivering the same breathing DNA as the XTX40 second stage, this stand-alone octo is engineered to be smooth, controllable, and unmissable when a dive suddenly turns into a drill.
Breathing consistency without the circus
Driven by a stable second stage breathing system, airflow remains dependable whether you're horizontal at depth or vertical during practice ascents. The over‑balanced hose pressure delivery upstream design philosophy keeps performance anchored as ambient pressure increases, meaning no spikes, no surprises — just calm, steady gas handover.
Share-ready. Shoulder-agnostic. Future-sensible.
The 36” yellow hose gives genuine donation reach without excess. Dual left/right feed regulator reversibility lets you route clean across classic backmount or lean technical setups without the dreaded hose twist dance. It sits close, routes clean, and plays nicely with transmitters and streamlined chest geometry.
Thermal grit
This octo is built for water colder than 10 °C — a reality in places from Loch Long to chilly channel-side ribs. Cold-water rated for reliable backup breathing, it resists freeze risks the smart way, not the complicated way.
Where safety meets smart
A big self-flushing purge gives rapid clearing and reliable reset. The progressive side-and-centre purge supports controlled SMB fills, not chaos blasts. The venturi lever disrupts airflow to avoid surface free-flows, keeping things tidy until you choose to purge. The Diver Changeable Exhaust system lets you switch bubble behaviour between compact routing or wider diversion — both exhaust tees included, no extra hunting required.
Comfort and conscience in equal measure
The patented Comfo-bite mouthpiece reduces jaw load and secures the reg more naturally, so long donations don’t mean long complaints. trivalent chrome plating protects the internals while using less energy to apply and being kinder on the environment. Even the packaging follows suit: no single-use plastics and a design homegrown right here in the UK.
