Divers must have a variety in equipment for technical diving. Backplates, which are used in conjunction with a harness, can be made of stainless steel or carbon fiber. Other technical dive gear includes dive knives, lights, rebreathers, stage tanks, safety buoys, and bailout bottles. These items will ensure that you are safe and comfortable while diving.
Technical divers may use certain equipment
Technical divers often use more advanced equipment 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 essential for long-duration dives and provide a layer of insulation to the wearer. Additional equipment include a compass (or a delayed surface marker buoy), a slate and compass. A decompression trapeze can help divers maintain correct depth during in-water decompression stops. You can also use a lift bag to transport the equipment.
The technical diver may also use a full mask to cover his nose, mouth, ears, and eyes. The safety harness can be used for lifting the diver out of water. A buddy line and shotline are two other items technical divers might need. A shotline, which is connected to a weight in shot to provide a reference point for a diver's descent, is a line that connects to a shotweight. A buddy line connects two divers in water to prevent them from getting separated. A jonline attaches the diver and to a shotline. A surface marker buoy shows the position of divers to the people at the top.
Equipment used for ice divers
Divers using ice diving equipment use multiple types of equipment to ensure safety. They generally use two-stage regulators. It allows divers to swap between the two regulators without needing a second tank. To replace the first-stage regulator that has failed, the diver can grab the second-stage one and attach it to its working counterpart. Ice divers often use double tanks, which provide redundant air delivery systems and air 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. The safety line can run up to 150 feet. In some cases, the two-person team may use separate lines. If the diver is separated from the line tenders, they may have to be covered in thermal protection.
The team must prepare the area before ice diving. The most common tool used for cutting the ice is a chainsaw. However, it should be used carefully. 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. This equipment includes a multigas dive computer, which tracks decompression requirements and allows the diver to switch between the two types of gases in a cylinder. You can also see the remaining air level in the tank with the submersible tension gauge. Another equipment used by decompression divers is a drysuit, which provides insulation during long diving.
Divers can use equipment that connects with a surface support platform in addition to their self-contained breathing apparatus. This equipment enables divers to perform a variety of underwater tasks, such as adjusting the stop depth or monitoring their depth. The umbilical provides the breathing gas for the diver's helmet. It may also contain two way communications, a depth measure tube, a camera, or hot water to warm his dive suit.
The jonline is another important piece of equipment for decompression divers. It is a long, flexible line that guides the diver throughout a search or work session. The lifting bag, an airtight bag attached with a weighted wire and suspended at depth in the diving chamber, is another piece. These tools are used by divers to lift heavy objects from deep seawater and use them for floats once they have been filled with air. The shot line is used by decompression divers to help them navigate to and from the surface.
