■ Installation of Shore Lights

For night diving, install and activate shore lights that emit 360-degree illumination at the entry point.

Prepare two shore lights. Position them at different heights and distances from the shoreline so that the exit point can be easily identified when viewed from offshore.

Ensure the lights are installed where trees or obstacles will not block visibility from the water.

The relative position of the two lights, as seen from the surface, allows you to determine your direction in relation to the entry point.

When viewing the entry point directly from offshore, the two lights will appear aligned in a straight line.

When viewing the entry point from the right side, the right-hand light will appear higher.

When viewing the entry point from the left side, the left-hand light will appear higher.
