■Descent rope and course rope

We are worried about our first night diving or poor visibility dive.
Descent rope or course rope may be used to remove such anxiety.

A nylon rope with a diameter of about 3 mm is suitable for the course rope.

When installing a course rope, wind the rope with a double chain on land, shorten the length of the rope, bring rope underwater, and take care so that the rope you are installing does not get tangled in the body underwater.

After installing the course rope, tie a chemical light to the course rope and let it emit light.

Installation of night diving descent rope and course rope should be completed at least 1 hour before sunset so that the rope does not get entangled with the diver in the dark.
