Second Stage REC1 O2 (Green)

Second stage ultralight in O2 version with high-visibility green cover, designed for use with pure Oxygen and hyperoxic mixtures. Constructed from high-resistance polyamide, it is equipped with a lever for Venturi effect adjustment and a wide exhaust deflector. The ideal choice for stage tanks and diving in temperate or warm waters.

The Tecline REC1 O2, available at DIR-STORE, is a compact and essential second stage, designed to offer maximum reliability and ease of use on the decompression tank.

The distinctive high-visibility green cover immediately identifies the regulator dedicated to hyperoxic/oxygen mixtures, increasing safety during gas switching. The polyamide construction makes the second stage incredibly lightweight (only 195 grams), eliminating jaw fatigue during long decompression stops. It is equipped with a lever for Venturi effect adjustment to prevent accidental free-flow before entering the water or during transport.
