Divers are trained to navigate with a continuous guideline
Cave divers are taught to use a continuous guideline to help them navigate safely from the entrance to the surface. These lines may be non-directional or directional, and must be visible even in low visibility. The diver's guideline is also referred to as the diver's jump line. It connects the diver’s lines.
Divers use three main types to navigate caves: The permanent line markers or line arrows are used to guide divers through the caves. The arrows are also used to indicate the direction to the exit. They are also used to indicate jump locations in the cave.
They must be capable of finding a lost guideline
A diver must be able to locate a lost guideline when they dive into a cave. There are several techniques that can help a diver locate a guideline. A touch signal, a compass or an underwater map are all possible ways to help a diver locate a guideline.
Guidelines are used to determine safe routes through caves. It is important to know how to use them. The length of the diver's dive will dictate whether the guideline should be mounted on a reel, or a spool. For example, an open water diver may only need to have a 50-metre guideline, while a cave diver may need several reels of varying lengths.
They need the right equipment
It is essential that you have the correct equipment for diving in caves. Cave water can get quite cold so it is advisable to have a suit on hand if you are planning a long dive. A waterproof notebook is also a great idea as it's handy for jotting down reference information during the dive. These notes are helpful for navigation inside the cave or during decompression.
Divers need to have extra fins and oxygen tubes. Cave diving can be dangerous so divers should have the correct equipment. Many caves have a high water pressure, and cave divers need to have specialized equipment. You should be cautious when choosing equipment.
They need to be disciplined and have self-control
You must have discipline and high levels of safety training to dive into caves. Cave divers are often limited in visibility, so cave divers must rely on their senses more than their knowledge. 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. The cave may be very tight and have high levels of silt. The dive to the end is quite simple but diver should not actively search for the marker. Blind staging, team protocols and simulation of a silty-out from a tank on sediment are part of the training process.
