An unbalanced first stage that works equally well in warm or cold water

The SUBEA SCD 100 regulator is a "club" regulator that stands out for its reliability, strength and easy maintenance. This SUBEA regulator is unbalanced, it works equally well in warm or cold water. It just requires greater ventilation effort according to the depth.

There is 1 high pressure (HP - 7/16”) outlet and 4 low pressure (LP - 3/8”) outlets.

Second stage and easy breathing

A regulator second stage has to translate natural breathing behaviour into mechanical reality. A high quality second stage can significantly reduce stress and help improve diver safety by providing air more easily and in sufficient quantity, without the need for unnecessary effort.

Breathing is easier thanks to the hydrodynamic openings in the cover. The exclusive design of the cover prevents continuous flow through the regulator

Exhalation: more visibility and less noise

When breathing out, ergonomic whiskers channel the flow of air bubbles to the cheeks so that the noise does not disturb the diver and so that the bubbles do not pass in front of the mask. Less disturbance and greater pleasure when diving!

SUBEA regulators: exclusive anatomical mouthpiece!

These regulator mouthpieces have been designed to be highly comfortable in the mouth thanks to their anatomical shape developed with orthodontists. The exclusive shape of this mouthpiece makes it easier to keep inside your mouth thanks to the bite wings, tongue support and the different thicknesses and densities of the material (mono and dual density) that take into account the jaw closure angle.

Regulator certification

This regulator is certified according to the standard EN 250:2014. Tested by RINA, Genoa, Italy (certified body N°0474). The tests are performed on a respiratory machine that simulates a diver’s breathing. The tests are performed at a pressure equivalent to a depth of 50 metres, with a ventilatory amplitude of 2.5 litres (breathing in and out), a ventilatory flow rate of 62.5 litres/minute, or 25 cycles per minute, and at a temperature of 10°C, or 4°C for cold water.

Certification and measurements of ventilatory effort

SUBEA SCD 100 regulators are equipped with an unbalanced first stage and are certified for use in cold water (<10°C) and warmer water (>10°C).

The INT regulator is certified to 232 bars.

Results of the ventilatory effort certification tests (simulated pressure at a depth of 50 m in water at 4 °C)

- tank pressure at 200 bars: 1.53 J/L

- tank pressure at 110 bars: 1.86 J/L

- tank pressure at 50 bars: 1.88 J/L.

Weight and length of the hose

Weight of the first stage: 660 grams.

Weight of the second stage: 200 grams.

Weight of the hose: 150 grams.

Total weight: 1040 grams.

Hose length: 75 cm.

Care instructions

Never use solvents or hydrocarbon-based products to clean or lubricate the regulator yourself. Never use spray cans, because the gas propellent can attack the plastic.

Servicing the regulators

SUBEA advises you to service your regulator every two years and to make a visual inspection at least once a year. These two inspections must be made in a SUBEA certified workshop.

A service is also recommended after a particularly intensive season (more than 100 dives), or after a long period of inactivity.

Tips for storage and maintenance

Storage tips

It is important to store diving equipment away from sources that produce ozone. Keep your equipment in a dry place away from heat and direct sunlight.


Test product

Our technical partner: Planet Ocean (the PADI 5-star diving centre) based at the WaterSports Centre by Decathlon in Hendaye - France. The centre uses SUBEA diving equipment throughout the year. The team of instructors are rigorously involved in the development of our SUBEA products: from the design phase with the teams (product managers, designers and engineers), to the endurance tests with the help of the centre’s divers (from beginners to trainee instructors, all year long).
