■Installation of shore light

For night diving, shore light that irradiates light 360 degrees is installed and turned on at the entry point.

We will prepare two shore lights and install them by changing the height of each light and the distance of each light from the shore so that the location of the exit can be easily seen when looking at the lights from offshore.

Install it in a place where trees do not block the light when viewed from offshore.

The position of the two lights visible from the water surface allows you to know which direction you are relative to the entry point.

If you look at the entry point from the front, you will see two lights in a straight line.

When looking at the entry point from the right, the light seen on the right appears to be high.

When looking at the entry point from the left, the light seen on the left appears to be high.
