Underwater lights are a necessity because the sunlight does not reach deep water and it is dark.
In dark waters, the buddy's underwater light can tell you where the buddy is.
■Rope
Prepare the rope for the descent line.
Attach a weight to the tip of the rope.
Fix the weight so that it does not move on the sea floor.
■Emergency scuba equipment
Prepare the safety stop bar and emergency scuba equipment in a safe stop position in case of an emergency decompression stop.
In addition, during a safe stop, buoyancy increases due to a decrease of residual tank pressure.
Put the wrist weight used for safety stop in a mesh bag and hang it on the safety stop bar.
