■Drifting

If you are swept away from the boat or the shore by the tide, swimming indiscriminately will drain your physical strength, so please secure buoyancy with BC and wait for rescue.

Diving service boats and rescue agencies that are familiar with the direction of the tide will find divers.

If air remains in the tank and buoyancy can be secured by BC, it is no need to throw away the weight belt.

Drifting groups should form a circle and act together.
