■Diving preparation

Connect the medium pressure hose to the air supply valve of the dry suit.

Thread the hose from the armpit

When checking equipment, be sure to check that the air supply / exhaust valve of the dry suit works properly.

Deflate the air from your dry suit before entry.

■Water surface movement

If you put air in the dry suit, resistance will increase and it will be difficult to swim, so BC will be used to secure buoyancy when moving on the water surface.
