PRODUCT DETAILS
Clear to see. Calm to breathe. Ready when it matters.
The Apeks EVX Octopus is the backup regulator that embodies control, clarity, and cold-water sensibility. Engineered as a stand-alone alternate 2nd stage, it delivers the same smooth inhale performance as the EVX platform — built to donate gas, clear efficiently, and stay composed in real-world out-of-air moments.
Balanced breathing, anytime, anywhere
A pneumatically-balanced valve keeps breathing effort smooth and stable across a wide temperature range. By managing opening resistance intelligently, inhalation stays predictable whether you're rescue-training, deploying an surface marker buoy, or handling stress-loaded ascents with a buddy in tow.
Routing freedom that fits your rig, not the other way around
The reversible gas feed orientation lets you configure the hose left or right for clean donation routing on both backmount and sidemount setups. The oversized, glove-friendly controls — from the tactile venturi lever to the progressive purge — make this octo genuinely mid-dive manageable, even under winter exposure protection like drysuit gloves.
Purge with purpose, reset with reliability
The 2-stage progressive purge gives you a gentle side-press for controlled fills, and a powerful centre-press for instant clearing. Every purge resets clean without sticky protest, resisting ingress from silted UK inland classics such as Stoney Cove or green-viz summer layers around the English Channel.
Thermal stability that steals warmth from the water
A patented heat exchanger surrounds the valve mechanism, dumping the cold of gas expansion while reclaiming ambient water warmth to improve breathing comfort in colder layers around the North Sea. Paired with the Diver Changeable Exhaust system, you can switch between compact or wide exhaust tees (both included) to control bubble interference and suit the dive task — from tight wreck run-throughs to open-water training circuits.
Comfort, durability, and future-first thinking
A low-stretch Comfo-bite mouthpiece reduces jaw load, holding the reg naturally without torque-pull fatigue. The flexible nylon braided hose stays supple in the cold where rubber stiffens into cable mode. Designed and manufactured in the UK, it arrives in environmentally considered packaging that avoids single-use plastic, reflecting the values of divers who explore iconic sites like Scapa Flow, and want gear built for years — not landfill.
