How to wear and use BC
(1) BC (buoyancy device) is worn behind the diving suit.
(2) The BC (buoyancy device) maintains a fist-wide tightness with the body (the chest state). Too tight will cause squeezing, and too loose will move up and down. To

(4) The principle of the buoyancy adjustment vest is that it is connected to the gas cylinder carried by the user through a hose. At this time, the gas in the gas cylinder is injected into the airbag of the buoyancy vest, similar to the swim bladder of a fish. The buoyancy is controlled by adjusting the amount of gas in the airbag.
Use of diving regulator
(1) First stage head: connected with gas cylinder valve. The function of the first stage is to reduce the air pressure in the cylinder to a medium pressure and then introduce it into several other pipelines.
(2) Second stage: At the end of this pipeline is the mouthpiece for your breathing. The function of the second stage is to accurately reduce the medium pressure air to the pressure level that you can breathe comfortably.
(3) Spare second stage: This device is the same as the second stage you use to breathe, but it allows you to easily share air with your partner when they need help. Sometimes the spare second stage is part of the buoyancy control (BC) charging/exhausting pipe.
(4) Low pressure inflation tubes: These tubes supply air to your buoyancy adjustment device (BC) (and dry suit; if you are wearing it) so that you can inflate to increase your buoyancy.
(5) Pressure gauge (SPG) tube: to send air to your pressure gauge, so that you can always know how much air is left in your cylinder.
