Additional information

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 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: 750 grams Weight of the second stage: 200 grams Weight of the hose: 150 grams Total weight: 1100 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). The DIN regulator is certified for 300 bars.
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.
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.
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.
What is the SUBEA brand?
Tribord Diving is now called SUBEA, the Decathlon brand dedicated to underwater sports (snorkelling, scuba diving, spearfishing and free-diving). The markings on all our diving products will gradually be replaced. Why SUBEA? Because: "SUBaquatic Experiences are Amazing"! For more information:

    El regulador bien, Decathlon muy mal

    En primer lugar decir que he tenido el regulador por mas de un año y la verdad es que funciona a la perfección, aunque es verdad que la segunda etapa no esta al nivel de suavidad que puede ofrecer la primera etapa. El problema viene cuando quieres comprar el kit de servicio para la primera etapa que es necesario cambiar anualmente. Decathlon simplemente no tiene el kit en venta, lo han eliminado de la venta, con lo cual después de un año puede que te quedes con un regulador al que no le puedes hacer mantenimiento. Actualmente están vendiendo este regulador sin ser posible comprar el kit de mantenimiento de juntas y filtro. Lo peor es que Decathlon sigue vendiendo el regulador actualmente y deberían dejar de venderlo. No lo compréis si no os garantizan la venta del kit de mantenimiento.

    Brand response :

    Buenos días Rubén. Gracias por tu valoración sobre nuestro regulador Subea 500. En primer lugar nos alegra que su funcionamiento a lo largo de este tiempo te satisfaga. Respecto al kit de mantenimiento, efectivamente no está a la venta al público, pero por una razón importante.
    La seguridad de nuestros productos es uno de los principios de Decathlon. Máxime tratándose de reguladores cuyo pleno funcionamiento es vital. Consideramos que la importancia de realizar el mantenimiento periódico conservando las máximas garantías de calidad y seguridad se consigue imprescindiblemente con el trabajo de profesionales debidamente formados. Por ello está restringido, y con ello los repuestos, a nuestro servicio técnico oficial.
    Por lo tanto el mantenimiento si está garantizado, entregando el regulador Subea así como de cualquier otra marca, en cualquiera de nuestros talleres situados en nuestras tiendas, que lo harán llegar a nuestro servicio técnico.

    Te animo a acercarte a tu tienda Decathlon más cercana para que podamos informarte y ofrecerte nuestro servicio.

    Para cualquier otra consulta o sugerencia no dudes en ponerte en contacto con nosotros.

    Gracias y un saludo.

    Manuel Sánchez-Mateos.

    Bon détendeur

    Un détendeur avec 1ier étage compensé qui tiend ses promesses. La respiration est agréable même à 40 m.
