Apeks MTX-RC STAGE3

The Apeks MTX-RC Stage 3 regulator is built for recreational divers who want dependable performance in a wide range of dive conditions, including cold water. Its over-balanced diaphragm first stage increases gas delivery as depth increases, ensuring smooth and effortless breathing even on deeper dives.

A forged first stage body with integrated heat-exchanging ribs improves thermal performance and helps prevent freezing in cold environments. The rotating turret and angled high-pressure ports allow for clean hose routing, better comfort, and easy integration with dive computers or transmitters.

The high-performance second stage is pneumatically balanced to deliver consistent airflow at any depth. A patented heat exchanger surrounds the valve mechanism, reducing cooling from gas expansion while drawing warmth from the surrounding water. Large protective bumpers and a reinforced front cover enhance durability, protecting the regulator from impacts during transport and use.

Comfort is further improved with a Comfo-Bite mouthpiece and flexible braided hoses with double swivels, allowing natural movement and reduced jaw fatigue. Tested and certified to EN250A standards, the Apeks MTX-RC Stage 3 is a dependable choice for recreational divers who value performance, durability, and cold-water reliability.
