Adjustment of flow and venturi effect.
The SCD 900 octopus is equipped with two settings on the second stage.
The first is the dive and pre-dive dial to avoid continuous flow, especially when entering the water.
The second is the flow control dial. Activating it adjusts the spring of the second stage. It thus makes it possible to increase or decrease the breathing effort during the dive.
Second stage and easy breathing
The second stage of the regulator has to translate natural breathing behaviour into mechanical reality. A high quality second stage significantly reduces stress and helps 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.
Breathing out: 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!
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.
SUBEA regulators: exclusive patented anatomical mouthpiece!
The exclusive shape of this mouthpiece, developed with orthodontists, 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.
The bi-density mouthpiece of the SCD 900 regulator has a zone in contact with the gums that is more sensitive than the rest of the mouthpiece in order to limit irritation.
Weight and length of the hose
Weight of the octopus with hose: 370 grams.
Hose length: 100 cm.
The base of the hose is made from antimicrobial thermoplastic polyurethane (TPU) polyether.
Outer coating: braided nylon for greater strength and suppleness. Withstands more twisting than conventional rubber hoses. Prevents the feeling that the regulator is pulling on the mouth.
To be fitted on a preferential intermediate-pressure port (LP – 3/8).
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.
Restrictions on use
Diving requires the certification of an instructor.
TESTS AND WARRANTY
Test product
Our technical partner: Planet Ocean (PADI 5-star diving centre) based at the Water Sports 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).
Warranty
