Restrictions on use
Diving requires the certification of an instructor.


A balanced piston first stage for easy breathing
The Subea 500 diving regulator first stage features a balanced piston with a swivel turret that improves breathing at any depth. There are 2 high pressure (HP) outlets and 4 low pressure (LP) outlets. Balanced piston first stages are the preferred choice for sport divers and demanding professionals. The hose is 75cm in length.
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 in 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!
SUBEA regulators: exclusive patented 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.
Weight and length of the hose
Weight of the first stage: 935 grams Weight of the second stage: 200 grams Total weight with hose: 1285 grams Length of the hose: 75 cm
Regulator certification
The SUBEA-TRIBORD SCD 500 regulators are equipped with a balanced first stage and certified for use in cold water non-cold water (temperature higher than +10°C).
Maintenance tips
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. This 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.
Storage advice
It is important to store all diving equipment well clear of sources that produce ozone (electric motors, cookers, etc.) and to protect it against UV rays. If this is not the case, the seals can deteriorate more quickly, affecting your safety or the working order of the regulator. Keep your equipment in a dry place away from heat and direct sunlight.
