Suitable for advanced and experienced divers

With a compensated membrane design, it allows deeper dives providing more natural breathing. Suitable for depths below 30 m.

The adjustable Venturi (dive/predive) has been prioritized in its design to prevent free flow on the surface and to reduce inhalation effort during the dive. The adjustment knob allows you to set your personal inhalation comfort. To provide comfortable and easy exhalation, the exhaust valve and cover offers minimum resistance, and the deflector has been designed to reduce bubbles on the diver’s face.

The LP hose is tested for a maximum pressure of 34 bar. The mouthpiece is made of high-end anti-allergic silicone for maximum comfort. The breathing work of the first and second stage IR-50 is an average of 0.84 J/L.

Compensated second stage:
Second stage compensation ensures that regardless of the residual pressure left in the cylinder, your inhalation comfort remains comfortable.

1. Controllable Venturi Effect:
By setting this to “-“, the Venturi effect is attenuated so that the second stage does not unintentionally blow off on land. Under water, the Venturi effect is then increased on the “+” setting, allowing for easy and comfortable inhalation.

2. Response Resistance Adjustment:
Every diver has a personal perception of the “optimal” inhalation resistance. Using the adjustment knob, everyone finds the best personal setting and thus maximum breathing comfort.

Our mouthpiece is also our own development and made of anti-allergic silicone. It guarantees a firm and comfortable fit in the jaw and can be changed in just a few steps if necessary. It is also available as a spare part in specialized shops.

Bubble deflector
Our bubble deflector is a step up from the previous standard. It directs gas bubbles away from their field of vision, but in conjunction with our enlarged exhalation membrane, it also lowers exhalation work, increasing the overall breathing comfort of our second stages.
