Care instructions
After a particularly intense season or after a long period of inactivity, TRIBORD recommends an inspection and a service annually or after 100 dives to maintain the guarantee.
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.


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.

    Pas utilisable dans les eaux du nord
    prix pas prévu pour eau < 10°c,

    J'ai acheté ce produit il y a 5 mois, a ce jour 50 plongées en eaux froide aux alentours de 8/10°C, dommage qu'en lisant la notice il ne soit pas prévu pour les eaux inférieures à 10°C, j'ai posé plusieurs fois la question au vendeur du pourquoi de ce problème alors que le simple détendeur que decathlon vend est plus moins cher peu être servit pour les eaux froides

    Bon rapport qualité prix
    rapport qualité prix, pas assez compensé, peu d'infos sur le site

    Ce détendeur est agréable à utiliser quelle que soit la profondeur. (testé jusqu'à 60 mètres) Je regrette toutefois vivement qu'il ne soit pas laissé le choix entre un DIN et un étrier lors de la commande. J'aurais aimé l'avoir en DIN mais pour ça il fallait prendre le lot complet avec octopus et manomètre. D'autant que je n'ai trouvé à aucun endroit dans le descriptif des détails sur le type étrier ou DIN sur le site, ni sur le nombre de bars maximum même si l'étrier est limité de facto à 232. Pour le côté compensé ça reste très léger on le sent très peu c'est dommage que ce ne soit pas la membrane qui est compensée.

    Bon détendeur (plongée Atlantique)
    Débit d'air fluide Pas testé sur plongée profonde, à voir

    Testé à Hendaye chez Planet Ocean sur plongées jusqu'à 35m.
    J'ai l'habitude de plonger en Scubapro mais j'avoue avoir été bluffé. Ce modèle Decathlon n'a rien a envier à d'autres grosses marques de plongée
