Technical diving requires divers to use a variety equipment. For example, backplates for harnesses are made from stainless steel, carbon fibre, or aluminum. Other technical dive gear includes dive knives, lights, rebreathers, stage tanks, safety buoys, and bailout bottles. These items are essential for your safety and comfort while you dive.
Equipment used by technical divers
Technical divers often use equipment that is more advanced than recreational divers. This equipment includes sophisticated gear that can be used in dangerous conditions and computers that monitor and record their dive data and decompression. Multigas dive computers are able to allow divers the ability to alter gas blends as they go and also control their decompression times. Submersible pressure meters are essential for divers. They allow them to check how much air is left in their cylinders. Dry suits are important for long-duration diving and offer insulation. A slate, compass and delayed surface buoy are all important diving equipment. A decompression trapeze can help divers maintain correct depth during in-water decompression stops. A lift bag is also used to carry the equipment.
Another equipment technical divers use is a full face mask. This covers the diver's nose and mouth as well as his eyes. A safety harness is also essential, as it can be used to lift the diver out of the water. A buddy line, shotline, and other equipment are also important for technical divers. A shotline can be a line attached to a gun weight to give divers a point of reference during their descent. A buddyline connects two divers in shallow water to one another and prevents them getting separated. A buddy line attaches the diver on a shotline. A surface marker buoy is used to indicate the divers' location to others.
Equipment used by ice divers
Safety reasons make it possible for ice divers to use different types of equipment. Two first-stage regulators are used by ice divers. It allows divers to swap between the two regulators without needing a second tank. The diver can simply attach the second-stage regulator to the broken first-stage regulator if it breaks. Ice divers frequently use double tanks which offer redundant air delivery and supplies.
Support personnel must be accessible above the ice when ice diving. The safety line attaches to the diver’s harness and serves as a communication device in an emergency. Safety lines can extend up to 150 feet. The two-person team might use separate lines in some instances. The line tenders need to be protected from heat and can have to go into the water in the event that the diver gets separated.
The team must prepare their area and cut a hole through the ice before they can go ice diving. Although the most common tool for cutting ice is the chainsaw it must be properly used. To avoid damage to equipment and divers, the hole should be smooth. Many ice divers choose to cut triangle-shaped holes, which provide a safer entry and exit.
Equipment used by decompression divers
When diving underwater, decompression divers need to use special equipment. The multigas dive computer tracks decompression requirements, and allows divers to switch between two types of gases in their cylinder. The submersible pressure indicator shows how much air is left in the cylinder. The dry suit provides insulation and protection during long dives.
Apart from a self-contained breath device, divers can also use equipment which connects to a platform for support. This equipment enables divers to perform a variety of underwater tasks, such as adjusting the stop depth or monitoring their depth. The umbilical supplies oxygen to the diver's head and can also be used to communicate with the other side.
Another piece of equipment that decompression divers use is the jonline. This is a long rope that is used to guide the diver in a search and/or work session. The lifting bag is another piece of equipment. It is an airtight bag that is attached to a weighted rope and suspended at the bottom. These tools allow divers to lift heavy objects out of the water and then use them as floats when filled with air. Shot lines are also used by decompression divers. They consist of a weight and a line that allow them to navigate to the surface, and then make a safety stop.
