SCD 500 B Scuba Diving Buoyancy Compensator
Filtered by translation missing: Loading reviews…
Well designed, Comfortable

Has adjustable cumberband, with modern style velcro, so no more fur collecting reducing its grip, & gives a comfortable fit, feels stirdy & robust, weight pockets will hold a 2kg & 1kg block & feels very comfortable, has standard style latch to hold them in place. D rings are nicely placed, cylinder strap grips well. Inflator & dump valves operate in a very nice controlled manor. Light weight for travelling, so back to Malta & the Red Sea My previous 4yr old Decathlon BCD, that I had throughout my training, (used & abused) is still going strong, but wanted to upgrade to back inflation style, My height 175cm, 75kg, (inc beer belly)

Perfect BCD at possibly cheapest price point

I just came back from a dive trip after using this. From my recreational and a less experienced diver (30 dives only) POV, it worked great for me. It was very comfortable, had lots of rings and clips to attach things, size was a great fit as well. Upon inflating it fully, it wasn't pushing me forward that much even when I had weights clipped on the back of the cylinder. It has two weight pockets on either side and two small pockets on the cylinder strap which helped me to distribute the weight evenly. Also, it comes with another big packet to keep a backup mask as well. I felt great with it underwater as well and was able to move my hand freely and adjust my straps and/or re-attach anything that was dangling inside the water. From 2-3 instructors POVs who were on the boat, it looked really well made for recreational diving and the quality felt good as well. For taking classes back inflation might not be the top choice but it looked good enough to stay on the surface comfortably as well. The lack of available sizes was the only issue that was pointed out. I bought the smallest one. Me being 5'9 and slightly chubby, it fit well but for most of the other guys, it was too big and there is a no smaller size available (at least on India store). Although, some of the instructors were interested in buying this in wholesale in 10-15 units for rental purposes for their shop as it is quite cheap and does what it says. Overall, considering the price point, it's an amazing deal and there is no other brand that provides this kind of BCD at such a low price with no cuts on the quality front. I sincerely hope DECATHLON provides more scuba products in India as they do in their other Thailand or Malaysia store. Especially this DIN/YOKE adapter - Since they have a DIN regulator and in India, most of the places have YOKE cylinders.


i am an instructor with SSI, and i recently got to use the BCD, SCUBA DIVING BUOYANCY COMPENSATOR WITH BACK BUOYANCY SCD 500 B, and i have surprisingly impressed by it, unlike conventional back inflated BCD , this doesn push me to fall forward when on the surface

Hi George.,

Feel free to write a review on other Decathlon products and I hope to see you in our store soon!



Trial Run in Open Water

Was given a chance to try out the latest BCD from Decathlon (Subea) in Open Water. Appreciate Anderson and team that made it happen. Initially I had some reservation given that Decathlon targeted market was for mass public. Thus the quality may likely go on par with the price (in some products). Also most people will go towards the better established brands in Scuba Diving. To my surprise, the quality of the BCD surpassed my expectation especially the workmanship and design of it. It was a hybrid of jacket and wing BCDs. Usage is quite at ease in terms of putting onto tank, insertion of weights, fixing up with regulator etc When it was used in Open Water, the BCD wrapped around your body as if it was worn like clothing. Working on the clips, hooks etc were not difficult too. With all the above pros on the BCD, one may wonder if there is any cons. In term of personal preference, I would prefer to have a smaller bladder to have a better wrap around your body. Now it seems that I am carrying a big shell over my back.

Hello Richard,

Thank you very much for your valuable review on one of our most technical scuba diving product.

I'm delighted to read that the SUBEA BCD 500 B surpassed your expectations.

Yes indeed, at Decathlon we make all sports accessible for the many by making our products very affordable. However, we really care of the quality and durability too.

This BCD is designed to be comfortable, easy to use and light weight, it's very nice to know that it fits the purpose.

Thank you also for the feedback about the bladder size, we'll try to consider it without compromising the lift that the BCD should provide.

Please feel free to contact me if you need more details about our scuba diving equipment.

Have a great day.

unschlagbarer Preis für super Wing

bin mit meinen Kauf sehr zufrieden. Bestellung/ Lieferung funktionierte problemlos. Tragekomfort ist viel besser als bei einer normalen Tarierweste.

super Weste

Ich besitze und tauche die Weste seit September 2019. Sie ist super angenehm zu tragen, sehr leicht und bietet einen starken Auftrieb. Die Lage mit der Weste ist immer stabil, auch Rückenlage und Drehungen sind ohne Anstrengung möglich. Beim Fotografieren sehr von Vorteil. In diesem Preissegment wird man keine angenehmere Weste finden. Salz- und Süßwasser sind kein Problem.

Klasse Tarierweste

Super Weste. Hatte vorher ein Masterjacket. Jetzt brauche ich keinen mehr, der mir beim Anziehen hilft. Bleitaschen sind gut zu belegen - rasten toll ein. Die Tasche zum Verstauen von Ersatzmaske und Taschenlampe reicht für mich aus. Halterung sind genug vorhanden. DTG lässt sich sehr gut befestigen. Das Ding ist einfach nur genial.

Excelente producto

Después de más de dos meses de uso puedo decir que es cómodo, ligero, práctico y con buena flotabilidad. Buena calidad y un precio razonable. Muy contento con la compra.

Chaleco completo a un precio inmejorable

Sinceramente, el chaleco de flotabilidad dorsal Subea 500B me ha sorprendido positivamente. Tras llevármelo a una serie de inmersiones a +30m y en sitios de acceso limitado como túneles y cuevas (zona Eden Roc, St Feliu de Guíxols), puedo asegurar que ha cumplido sobradamente con su cometido. De hecho, tiene detalles de chalecos de rango de precio muy superior, como el bolsillo en el lado derecho, la cantidad de anillas en D, los dos clips para sujetar latiguillos con los que viene de serie, la sensacional comodidad del backpack e incluso lo bien que van los bolsillos de lastre integrado, que a diferencia de modelos de otras marcas, se deslizan bien en su compartimento cargados y con el chaleco equipado. En el agua se comporta muy bien, permitiendo una cómoda y eficaz posición horizontal/trimado, el hinchado es suave y el vaciado a través de sus válvulas también, aunque en mi caso hubiese preferido que la válvula de purga inferior posterior estuviese en la cara exterior del saco, aunque esa es una preferencia personal. En definitiva, si lo que estás buscando es un chaleco todo-terreno que pueda llevarte a casi cualquier lugar con seguridad y eficacia, el SCD 500B es para ti. Joel Ingalaturre

Vieillie très mal après à peine un an...

L'enveloppe ne tient plus sur la plaque dorsale, obligé de mettre un système (rilsans) en place pour ne plus que l'enveloppe se détache et empêche d'être stable avec le bloc. La purge lente est trop basse pour s'en servir facilement, la purge rapide est mal positionnée aussi. Après une petite centaine de plongée avec cette stab je ne recommande pas ce produit, ou alors à un bon bricoleur qui saura l'adapter. Mais bricoler du matériel de plongée (surtout neuf)....

J'ai lu attentivement votre commentaire et vous remercie d'avoir pris le temps de le faire.

Je vous invite à revenir en magasin avec votre gilet stabilisateur pour faire constater le défaut et obtenir son échange.

Concernant le placement des purges, je prends bien note de vos constats et vais analyser cela avec l'ingénieur en charge de nos stabs.

Je vous présente toutes mes excuses pour les désagréments rencontrées et vous souhaite de très belles plongées !

François Guillaume, Chef de produit plongée bouteille

Une dorsale change votre façon de plonger

Je trouve que l'inflateur se trouve un peu trop haut et que les purges sont trop petites. Une dorsale change complètement votre façon de plonger, par rapport à une enveloppante. Comme j'ai vu dans les précédents commentaires, il faut prévoir 1 à 1,5 kg de lestage en plus.

Additional Product informations


Main fabric

  • 100% Polyamide

Type of bcd

The SUBEA diving buoyancy compensator SCD 500B is a "back buoyancy" BC: the volume of air is on the back only. This allows for a better balance in the water and completely frees your arms. No more air volumes on the sides that can hinder movement under and out of the water.The SCD 500B harness is separate from the bladder, so you don't feel the pressure when the BC is inflated.

Ease of use

The BC has a dump valve that helps stop water getting into the bladder: a valve located under the upper drain and the lower drain prevents water from entering when the valves are activated.The choice of the shape and the colour of the purge pull tabs also makes for an easier grip.The buckles on the straps allow for easy and accurate adjustment thanks to their shape and size.

Weight system

The SCD 500B BC has two releasable weight pockets on the sides, complete with a neon yellow quick-release buckle. Capacity: 3 kg each.It also has two back pockets (located on the cylinder strap) that can each support 2 kg.

Carrying comfort

Available in 2 sizes (S/M and L/XL). The stomach strap is adjustable in length for all body sizes: there is a rip-tab system at the back for it for a snug fit.For added comfort, SUBEA design teams have developed reinforced back padding on the back of the buoyancy compensators, to cushion the tank. The braces are also padded and made of 3D mesh for greater suppleness on the shoulders.
