BC is not used to control buoyancy in underwater.
BC is used only to secure buoyancy on the water surface.
In underwater, adjust the buoyancy by supplying / exhausting air to the dry suit.
Supply and exhaust air little by little like BC.
The automatic exhaust valve automatically exhausts when the set pressure is reached.
By rotating the ring on the outside of the valve, the air volume in the dry suit can be kept constant and neutral buoyancy can be maintained depending on diving depth.
Please note that if you are standing upright in the water, air will accumulate in your legs and you will not be able to control buoyancy. |
Neutral buoyancy is adjusted by a dry suit. |
