Divers are taught how to navigate with a continuous guidanceline
To make cave diving easier and safer, divers learn to use a continuous line of guidance. These lines can either be non-directional (or directional) and must be visible in total darkness. The diver's guideline is also referred to as the diver's jump line. It connects all diver's lines. In the event of a problem, it can also be used as a safety guideline.
Three main types of marker are used by divers to help them navigate the caves. The permanent line markers or line arrows are used to guide divers through the caves. The arrows also indicate the direction of the exit. They are also used to indicate jump locations in the cave.
They should be able find lost guidelines.
When diving into caves, one of the most important safety skills a diver should possess is the ability to locate a lost line. There are many techniques that can be used to help a diver find a guideline. Using a touch signal, a compass, or an underwater map can all be helpful.
The guideline is used for marking safe routes through caves. Every diver should be familiar with how to use it. The length of the diver's dive will dictate whether the guideline should be mounted on a reel, or a spool. An open water diver might only require a 50-metre guideline. A cave diver may need multiple reels of different lengths.
They should have the correct equipment
You need to be comfortable and safe when diving in caves. Cave water can be very cold so it's a good idea to have a wetsuit if you plan on doing a long dive. It's a good idea to have a waterproof notebook handy so you can keep track of any important information. These notes are helpful for navigation inside the cave or during decompression.
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. Many caves have a high water pressure, and cave divers need to have specialized equipment. 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 need to be able see clearly in caves. Cave divers need to be able and able maintain their calmness in difficult situations.
Once the diver is inside the cave, he or she must take the scooter off and swim 3-4 hundred feet to the end. Some parts of the cave are very narrow and may contain large quantities of silt. A dive to the end of the line is relatively simple, but the diver should not actively seek the end marker. The training process involves team protocols, blind staging, and simulation of a silt-out caused by a tank dropped on sediment.
