■Descent Rope and Course Rope

Night diving or limited-visibility diving may feel challenging, especially for beginners.
A descent rope or course rope can help reduce anxiety and improve safety.

A nylon rope approximately 3 mm in diameter is suitable for use as a course rope.

Before entering the water, neatly coil the rope on land to shorten its length and make it easier to handle. When deploying the rope underwater, take care to prevent it from becoming entangled around your body or equipment.

After installing the course rope, attach chemical lights at intervals to improve visibility.

Installation of descent ropes and course ropes for night diving should be completed at least one hour before sunset to ensure safe setup and avoid entanglement in darkness.
