Technical diving requires a variety of different equipment. For example, backplates for harnesses are made from stainless steel, carbon fibre, 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 are used to ensure your safety and comfort while diving.
Technical divers often use the following equipment:
Equipment used by technical divers is often more advanced than that used by 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 gauges are an essential tool for divers. These gauges allow them to see how much air they have and help them monitor their cylinders. For long-duration dives, dry suits provide insulation and are essential. Another diving equipment is a slate, compasses, 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.
Other equipment used by technical divers includes a full face mask that covers the diver's nose, mouth, and eyes. It can also be used to lift the diver from the water. A buddy line, shotline, and other equipment are also important for technical divers. A shotline is a line connected to a shot weight to give a diver a reference point for their descent. A buddyline is used to connect two divers in the sea and prevent them from becoming 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 by Ice Divers
Safety reasons make it possible for ice divers to use different types of equipment. They usually use two first-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 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 is clipped to the diver's harness and acts as a communication device in case of an emergency. The safety line can be as long as 150 feet. In some cases, the two-person team may use separate lines. Line tenders should be wearing thermal protection, and may need to get into the water if they become separated from the diver.
Before ice diving, the team must prepare the area and cut a hole in the ice. 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 divers for decompression
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. 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 use equipment that connects and is independent of their breathing device. Divers can use this equipment to adjust the stop depth and monitor their depth. The umbilical supplies breathing gas to the helmet of the diver. It may also have two-way communication, a depth measuring tube, a camera and hot water to warm the 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 enable the diver to lift heavy items from the bottom and use them as floating objects when they are full. 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.
