Mr.Penn delos Santos

Here’s my review of the SUBEA Regulator. Let me know when you receive this. Cheers! Penn SUBEA REGULATOR REVIEW The SUBEA SCD500 DIN scuba regulator is Decathlon’s latest offering from their scuba diving equipment line. The SCD500 set comes with a DIN first stage, primary and alternate second stages, and submersible pressure gauge. Although the first stage is DIN, there is an available international yoke adaptor that can be purchased from Decathlon. You will also need to install a low-pressure hose to be attached to the bcd power inflator. A handsome regulator bag also comes with the set to protect the SCD500 from bumps and scratches when you store them. As stated in the SCD500 owner’s manual, it is specifically designed for recreational diving purposes. The first stage is a balanced piston regulator and can take tank pressures from 232Bar (Yoke) to 300Bar (DIN). It has 4 low-pressure and 2 high-pressure hose ports. A DIN screw-on dust cap also comes with the package for protecting the first stage when not in use. The SUBEA pressure gauge is in metric units and comes with a rubber housing. Both the primary and alternate second stages are standard regulators with internal venturi mechanism to provide maximum ease of breathing. The hoses for the SPG and the two regulators comes in standard lengths and in different colors for easier identification (dark grey for primary, yellow for alternate, and black for SPG). Test dive. I was impressed with the packaging of the SCD500 that was sent for testing. The Decathlon eco-bag is a good idea to avoid plastic use, and the regulator bag is really very handsomely done in black color. I had to reconfigure the placements of the hoses before I can use the set as the second stages were located on both sides and the pressure gauge was on the right. I also had to attach a low-pressure inflator mmhose to complete the set-up. The DIN screw grip is easy to use when attaching it to the tank and sits perfectly stable with the tank valve. The hose lengths are also comfortably sized for recreational diving, they do not dangle around when properly attached with a clip to my bcd. During my test dive I incidentally had some guests for discover scuba diving lessons. During the swimming pool dives I found out that the second stages would free flow when they are dipped mouthpiece-down in the the water, so I made sure to take note of that and be more cautious to save my air. Both the primary and alternate regulators delivered maximum ease of breathing in the swimming pool. The SPG can easily be seen with its white and orange colored face. For the open water test dive I initially brought the SCD500 down to a maximum of 12 meters. The first stage performed very well, with no visible bubbles coming from the valve and the hose ports. The primary and alternate second stages also delivered exceptionally well during the dive with no changes on the ease of breathing. For my second dive I went to a maximum

Excellent set of regulators

Recently I got bought a set after reading the specifications. It's great value for money given the first stage is a swirl turret. I just did 2 dives with it at Singapore southern islands and was surprise at how easier the air flow was underwater; the dive depth was 19m. However the primary regulator during pre-dive check had free flow when I depress the purge button, but I think it's fine. You will have the same problem with venturi base regulators, this proves that it will breath easy. I have 1 concern which Decathlon has addressed, which is the bi-yearly service of the regulators. Decathlon has assured me that their service center in Bedok will handle it, which would be good if I don't have to bring it to 3rd party service center. I'm getting a 2nd set for my daughter, but will have to wait until the lockdown for COVID-19 is over. Decathlon pls reserve a set for case there was a mad rush for the item :) To the Subea Team...pls keep up the good work, and stay save during the lockdown.

Hello John,

Thank you so much for your review.

We really appreciate that you give us so much details about your experience with your SUBEA SCD 500 regulator.

The regulator is such an important player during your dives, for the comfort but most importantly for the safety. Thank you for trusting us.

We are delighted that you enjoyed its easy breathing effort and its turret for a comfortable hose routing.

FYI, when it's time time service your regulator, our technician is based at Bedok store but you can bring it back to any other outlets and we will do the transfer for you.

We can reserve a regulator set for the end of the circuit breaker period but you may also consider to buy it online and enjoy the free delivery.

We wish more amazing dives ahead.

Have a nice day.

Make bubbles & smile

SCD500 good but no service in Thailand

I have 2 regulators SCD500. They work fine but Decathlon do not service them in Thailand. As this product need regular servicing, it is a problem if you are not able to do it yourself.

Solide Technik

Beim Tauchen im Mittelmeer (12..20 °C) war die Leichtgängigkeit der Atmung in der ersten Stufe sehr gut, nach dem Auftauchen bzw. vor dem Abtauschen an der Wasseroberfläche könnte sie leichter sein, d.h. die Atmung war leicht erschwert. Ansonsten ist es eine solide und bisher sichere Technik.

Calidad precio muy compensado

Excelente pack, usado y probado muy satisfecho con el.

Gran producto, mejor precio

excepcional en todo, muy cómodo, buen caudal, para mi gusto solo necesita mejorar en un regulador de caudal, gran conjunto.


Es un magnífico producto no a dado ningún problema y lo mejor de todo es el precio hace que sea muy accesible para cualquiera que se quiera iniciar en el buceo

Muchas gracias por tus comentarios Angel.

¡ Te esperamos pronto !

Qualité moyenne

Facile à transporter avec le sac de rangement fourni se fermant au moyen d’une tirette, bien grand donc très pratique. Le détendeur fonctionne très bien en eau froide à des plongées à +/-20mètres. Je l’ai utilisé une seule fois en eau chaude et là, j’ai eu la mauvaise surprise qu’il s’est mit en débit continu à plusieurs reprises; à surveiller donc...

Bon rapport qualité prix sauf embout

De bonne facture la respiration se fait sans difficulté particulière. Seul bémol l'embout fournit sur le détendeur s'avère trop souple. La conséquence est que ce dernier se plie parfois en raison du poids du détendeur et laisse ainsi rentrer de l'eau dans la bouche lors de l'aspiration. A changer par un embout plus rigide.

très bien excellent rapport qualité-prix

excellent détendeur Un tout petit peu plus gros qu'une marque très connu ,donc Un tout petit peu plus lourd . quelques petites choses à dire quand même : je trouve le flexible gris Un peu court. l Octopus pourrais être réversible. quant à l embout : personnellement je le trouve pas confortable , comme tout les détendeur de plongée il se change facilement et vous pouvez mettre votre embout préféré à la place.ce qui me dérange le plus c'est qu'il ne soit pas sécurisées par un rizlan. operation très facile à faire qui vous évitera en cas d arrachage de votre détendeur de vous retrouver avec l embout en bouche,de croire qu'il y a de l'air,et de boire la tasse.

Additional Product Information


Chassis: 75.0% Polyamide 12, 5.0% Steel, 5.0% Silicone, 15.0% Brass ; Yoke: 100.0% Brass ; Pocket: 100.0% Polyester cationic

Pack composition

The pack includes:1 DIN Subea SCD 500 regulator with compensated piston (29.5” hose) 1 Subea SCD octopus surface indicator (39.4” hose) 1 SCD SUBEA pressure gauge

A balanced piston first stage for easy breathing

The first stage of the SUBEA 500 diving regulator is made of chrome-plated brass, with a balanced piston. The average pressure received by the second stage is constant in order to maintain the performance of the regulator, which also remains constant throughout the dive. The SCD 500 regulator is fitted with a pivoting turret to hold the hoses in the right direction around the head. There are 2 high-pressure (HP - 7/16”) outlets and 4 medium-pressure (LP - 3/8”) outlets.

Second stage and easy breathing

A regulator's second stage has to translate natural breathing behavior 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 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.

The subea diving octopus is a valve second stage, with a large diaphragm and a purge button.

Its simple and robust design provides long-lasting reliability and makes the SCD octopus the ideal second stage for new divers, as well as the perfect choice for safe diving thanks to its 39.4” yellow hose for easy air sharing.

Subea pressure gauge: diving pressure gauge for tank pressures of up to 300 bars

300-bar pressure gauge with stainless 1-piece chrome-plated brass housing, explosion-proof, shock-proof.Copper-beryllium sensitive spiral element.Hose with an outer diameter of 55 mm. Male screw thread. 7/16'' HP.Highlighting of the red zone between 50 bar and 0 bar for greater clarity and safety.Extra ring on the side to attach the pressure gauge and keep it within reach thanks to the safety strap.

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 164'' with a ventilatory amplitude of 2.5 liters (breathing in and out), a ventilatory flow rate of 62.5 liters/minute or 25 cycles per minute and at a temperature of 50°F, or 39°F for cold water.

Certification and measurements of ventilatory effort

The SUBEA SCD 500 regulators are equipped with a balanced first stage and certified for use in non-cold water (temperature higher than 50°F). The DIN regulator is certified for 300 bars.Results of the ventilatory effort certification tests (simulated pressure at a depth of 164' in water at 46°F) - tank pressure at 50 to 200 bars: 1.4 J/L. The ventilatory effort is the measurement of the energy (in Joules) required for 1 liter of ventilation.
