Divers are trained to navigate with a continuous guideline
Divers are trained to use a continuous guideline in cave diving, to make the journey from the entrance to the surface easier and safer. These lines can either be non-directional (or directional) and must be visible in total darkness. The diver’s guideline (also known as the diver’s jump line) is also called the diver’s safety line. It connects the diver’s lines and serves as a safety rope in case of emergency.
Divers use three main types to navigate caves: The permanent line markers or line arrows are used to guide divers through the caves. They can also be used as a way to point to the exit. They may also mark jump locations within the cave.
They must be able to find a lost guideline
One of the most crucial safety skills a diver should have is the ability find a lost reference line when diving into a cave. A diver can use several methods to find a guideline. You can use a touch signal or an underwater chart to locate a guideline.

Guidelines are used to determine safe routes through caves. It is important to know how to use them. Depending on how deep the diver must dive, the guideline is usually mounted on a reel. Open water divers might only need a 50-meter guideline while cave divers may require several reels of varying lengths.
They must have the appropriate equipment
For cave diving, it is important to have the proper equipment. Cave water is quite cold. If you're going to be doing a long diving trip, you should consider wearing a wetsuit. A waterproof notebook is also a great idea as it's handy for jotting down reference information during the dive. These notes can be helpful during decompression stops or navigation within the cave.
Divers should also have extra fins and oxygen cylinders. Cave diving can be dangerous and divers need to have the proper equipment in order to avoid injury. Cave divers require specialized equipment, as many caves can be dangerous due to their high water pressure. You need to be careful when selecting your equipment.
They must have disciplined self control
Diving into caves requires disciplined self-control and a high level of safety training. Cave divers must be able to use their senses and not rely on their knowledge of cave environments. Cave divers must be able control their breathing and maintain calm under pressure.

Once in the cave, the diver should drop his scooter and swim the three- to four hundred foot distance until the end. Some caves are extremely narrow and can contain large amounts of silt. Although it is easy to dive to the end, the diver should not actively seek out the end marker. Blind staging, team protocols and simulation of a silty-out from a tank on sediment are part of the training process.
