Technical Information

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.
Accessories to attach and store your equipment
six carry rings: one 3D anodised ring on the left shoulder and two on the right, two 3D anodised rings at the hips and two PVC rings on the stomach. Comes with two hose holder hooks. The chest strap has a built-in whistle to call for help on the surface. one detachable accessories pocket that can be adjusted to the right or left to transport a few small accessories, such as a mask, or a surface marker.
Carrying comfort
Available in two 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.
Sizes and Buoyancy
The Subea SCD 500 B BC is available in two sizes: S/M buoyancy = 140 N (15 L steel tank) L/XL buoyancy = 210 N (15 L steel tank) SUBEA BCDs meet the standard EN 1809: 2014 + A1 2016(latest version of the standard). They are certified by the INPP (French professional diving institute) in Marseilles, France.

Maintenance advice
1/ Rinse your buoyancy compensator thoroughly with clean water. Pay particular attention to the drains and the inflater. 2/ Empty any water that may be contained in the buoyancy compensator by pulling the lower drain tab. Do not store water in the inflatable bladder. 3/ Dry your buoyancy compensator on a wide hanger, out of the sun. Inspect your buoyancy compensator once a year and look for any signs of wear. Inflate the inflatable chamber by mouth, then wait 12 hours to see if it deflates.
Servicing buoyancy compensators
Your buoyancy compensator must be inspected and serviced by a certified SUBEA centre at least every two years, and more often if you are a frequent diver. After Sales Service:
