PRODUCT DETAILS
Stage-3 Ready. Cold-Water Proven. Depth-Stable by Design.
BACK IN STOCK MID FEB 2026
The Apeks EVX200 Stage3 Regulator Set gives you what every committed diver really needs: a fully matched primary and octopus regulator system, engineered and built in the UK, leaving just one final piece to add — your pressure gauge for a Stage-4 rig. No mismatched backup. No weak link. Just a cohesive breathing system designed to perform as a unit.
Descent-Activated Performance
The over-balanced diaphragm design increases medium-pressure gas delivery to your hoses faster than ambient pressure rises on descent, keeping airflow powerful, stable, and consistent as you go deeper. The result is controlled, natural breathing at depth — where lesser regs drift, the EVX200 stays anchored.
Cold Isn’t an Environment, It’s a Requirement
With a PVD-coated brass body enhanced by heat-exchange ribs and a ribbed diaphragm clamp, this first stage actively fights thermal loss in water that would rather punish your kit. The Auto Closure Device seals the internals when disconnected, stopping water ingress at the source — especially valuable in British conditions where silt, spray and winter chills are part of the deal.
Five medium-pressure ports unlock cleaner, more intuitive hose routing across backmount rigs, while dual angled HP ports allow secure alignment and effortless transmitter fitting for wireless dive tech like Ratio or compact pressure senders. A double-swivel hose connection reduces torque, increases mobility, and keeps your head movement relaxed — even on long profiles.
Precision, Control, Redundancy
The EVX200 second stage runs on a pneumatically balanced poppet valve for smooth inhalation stability, backed by a large, glove-friendly breathing adjuster that lets you fine-tune cracking effort mid-dive without fumbling focus. The Laminar Flow Valve reduces turbulence, increasing smoothness and consistency breath-to-breath.
The reversible design lets you flip the gas feed left or right, ideal for sidemount routing, primary donation training, or stage placements. The 2-stage purge button offers a controlled side-press for delicate tasks like SMB inflation, then a full centre purge for powerful clearing when conditions demand it.
Customised Exhale, Same Powerful Return
The Diver Changeable Exhaust system lets you choose between a small exhaust tee (minimal bubble disturbance, tighter rig geometry) or a large exhaust tee (wider dispersal, quieter exhale, increased comfort). Both are supplied, no extra purchases, no up-sell required.
Comfort That Doesn’t Quit When the Water Turns
A flexible braided nylon hose stays supple in the cold where rubber stiffens into protest. The Comfo-Bite mouthpiece reduces jaw tension to the point you forget it ever existed. A patented heat exchanger wraps the valve mechanism, dissipating cooling from gas expansion while reclaiming ambient water warmth into every inhale.
Even the packaging shares the ethos of UK divers — plastic-free, mission-focused, long-term thinking, not disposable mindset.
Stage-3 Divers Choose It Because:
✔ Matched primary + octopus (just add SPG later)
✔ Depth-stable over-balanced pressure delivery
✔ PVD-protected brass body built for cold-water diving
✔ Auto-sealing internals stop water ingress at disconnection
✔ 5 MP ports + angled HP ports for logical hose routing
✔ Reversible 2nd stage for donation and stage routing
✔ Dual exhaust tees included for custom exhale control
✔ Braided hose performs in the cold where rubber fails
✔ UK-designed, sustainable-packaged, dive-first thinking
If British water tests your gear — this is the one that passes.
