Leave your underwater camera etc. on the boat at the time of entry and receive it from the boat staff after entry.

For preventing accidents due to falling, heavy equipment such as underwater scooters are received underwater using gear lines.

Even if the engine is off, be careful not to approach the screw during entry, just in case.
If you get caught in a screw, it will be a big accident.

Also, get away from the swaying boat as soon as possible and avoid hitting the boat.
