Divers are trained with a continuous guideline to help them navigate.
To make the journey from cave diving safer and easier for divers, they are trained to use continuous guides in cave diving. These lines can either be non-directional (or directional) and must be visible in total darkness. The diver's guidance line is also known as the diver’s jumping line. It connects the diver's lines and is also used as a safety line in case of a problem.
Divers can use three types or markers to help guide them through the caves. Line arrows (or permanent line markers) can be used as visual and tactile guides. Arrows can also be used to indicate direction to exit. They can also be used to mark jump points within the cave.
They must be able and willing to search for a lost guideline
When diving into caves, one of the most important safety skills a diver should possess is the ability to locate a lost line. A diver can use several methods to find a guideline. An underwater map, touch signal, or compass can all help to locate a guideline.
The guideline is used to mark a safe route through a cave and diver should know how to use it. Depending on how far the diver is going to be diving, the guideline will often be attached to a reel or spool. An example of this is an open water diver who may only require a 50-metre guidance line. However, a cave diver will need multiple reels with different lengths.
They must have the right equipment
For cave diving, it is important to have the proper equipment. Cave water can be extremely cold so you might want to bring a suit for long dives. You can also use a waterproof notebook to keep track of important information while diving. These notes are useful for navigation and decompression in the cave.
Divers need to have extra fins and oxygen tubes. Cave diving can be dangerous so divers should have the correct equipment. Cave divers should have specialized equipment as there is often high water pressure in caves. This equipment can weigh a lot, so it's important to be careful in choosing your equipment.
They must have disciplined self control
Cave diving requires self-control and safety training. The cave environment often provides little visibility and cave divers have to function on their senses rather than on their knowledge of the environment. A cave diver must be able to control his or her breathing and remain calm in such situations.
Once inside the cave the diver must get off the scooter and swim about three to four hundreds feet until the line ends. Some parts of the cave can be extremely tight and contain high amounts of silt. A dive to the end of the line is relatively simple, but the diver should not actively seek the end marker. Team protocols, blind staging, simulation of a silt out caused by a tank being dropped on sediment are all part of the training process.
