■Night diving

Learn adult nightlife

Experience a visit to the mysterious night sea.

You will be impressed by the world you see for the first time: fish sleeping, shrimp and other
nocturnal creatures walking, and nocturnal insects sparkling in the water at night.

It is a little dark, but you will be fine if you have an underwater light.

Don't worry, there are no ghosts.! ?


Night diving method

The instructor may set up a course rope in the water area where the night dive is scheduled
.
The course rope will be used as the route for the night dive.

When setting up the course rope, follow behind the instructor and observe the general topography and life at the dive site.

*Note
Local rules prohibit night diving at some dive sites. Check in advance.


Hand signal

To signal your buddy or another diver, point your underwater light at the diver's body or in the diver's
field of vision and wave the light so that it wiggles slightly.

If the diver still does not notice you, signal by touching your buddy's arm.

Avoid touching the diver's feet to avoid being kicked in the head by the diver's fins.

When night diving, hand signals are made by shining the light of an underwater light on your hands.

If there is a person next to you, you may shine the light on your chest and give the hand signal in
front of your chest to avoid accidentally shining the light on the face of the person next to you.

Discuss one-handed hand signals before diving.
