Divers must have a variety in equipment for technical diving. Backplates with a harness, for instance, are made of stainless steel, carbon fiber, or aluminum. Diver tools such as lights, rebreathers and stage tanks, safety buoys and bailout bottles are all part of technical diving gear. These items can be used to ensure safety and comfort when diving.
Technical divers may use certain equipment
Technical divers often use equipment that is more advanced than recreational divers. These equipment can be used under hazardous conditions. They also have sophisticated computers that allow them to monitor their decompression and other dive related data. For instance, multigas dive computers allow divers to change gas blends on the fly and control their decompression time. Submersible pressure gags are also vital. They help divers check the amount of air in their tanks. Dry suits provide insulation for long-duration dives. Other diving equipment includes a slate, compass, and delayed surface marker buoy. A decompression trapeze can help divers maintain correct depth during in-water decompression stops. A lift bag is also used to carry the equipment.
A full face mask is used by technical divers to cover the nose, mouth and eyes. Safety harnesses are also important as they can be used to lift divers out of the water. A buddy line and shotline are two other items technical divers might need. A shotline connects to a shotweight to provide a reference point to the diver for their descent. A buddy line connects two divers in the water to each other and prevents them from becoming separated. A jonline tethers the diver to a shotline, and a surface marker buoy indicates the position of the divers to people at the surface.
Equipment used for ice divers
To ensure their safety, divers use multiple types equipment. They generally use two-stage regulators. This allows them to switch between the regulators without the need of 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.
It is essential that you have support personnel available while ice diving. The safety line is clipped to the diver's harness and acts as a communication device in case of an emergency. The safety line can reach up to 150 feet. Sometimes the two-person line tenders may use separate lines. 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 the area before ice diving. While the most common tool to cut ice is the chainsaw (but it must be used with care), it is still very useful. The hole should not be too rough to cause damage to the equipment or diver. Many ice divers use triangle-shaped holes to provide safer entry and exit.
Equipment used for decompression divers
Decompression divers use specialized equipment when they are underwater. 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.
Apart from a self-contained breath device, divers can also use equipment which connects to a platform for support. Divers can also use this equipment to adjust their stop depth or monitor 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.
A jonline, a long-lined instrument used by divers to aid in their search and work sessions, is an important piece. A lifting bag is another important piece of equipment. This is an airtight bag which is attached to a heavy line and suspended at bottom of diving chamber. 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. 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.
