Technical diving requires a variety of different equipment. For instance, backplates used with a harness are made of aluminum, carbon fiber or stainless steel. Other technical dive gear includes dive knives, lights, rebreathers, stage tanks, safety buoys, and bailout bottles. These items are necessary to ensure your safety while diving.
Technical divers use equipment
Technical divers often use more advanced equipment than recreational divers. It may include special gear that can only be used in extreme conditions. Additionally, it includes sophisticated computers that aid them in monitoring their decompression, as well as other data. Multigas dive computers, for example, allow divers to adjust gas mixtures and control decompression time on the fly. Submersible pressure gauges, which allow divers to monitor the level of air in their cylinders, are also important. Dry suits are necessary for long-duration divers and provide insulation. You can also use a compass, slate, or delayed surface marker buoy as 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. Safety harnesses are also important as they can be used to lift divers out of the water. Technical divers might also need a buddy line and a shotline. A shotline is a line connected to a shot weight to give a diver a reference point for their descent. A buddy line is a connection between two divers in the water that prevents them becoming separated. A jonline ties the diver onto a shotline. An underwater marker buoy marks the divers' position to those 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. In the event that the first-stage regulator fails, the diver can easily attach the second stage regulator to the damaged one. Double tanks are used by ice divers to provide redundant air supply and delivery systems.
Support personnel must always be on hand for ice divers. The safety line attaches to the diver’s harness and serves as a communication device in an emergency. The safety line can reach up to 150 feet. Sometimes, the two-person team may have separate lines. If the diver is not able to reach them, the line tenders will need to wear thermal protection.
Before diving, it is important to prepare the area and make a hole in 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 prefer to make triangle-shaped holes. This allows for safer entry and exit.
Equipment used by decompression divers
For decompression diving, special equipment is required. Multigas dive computers, which track decompression requirements and allow the diver to switch among the two types in a container, are part of this equipment. The submersible pressure indicator shows how much air is left in the cylinder. 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 perform many underwater tasks using this equipment, including adjusting their stop depth or monitoring it. The umbilical supplies the breathing gas to the diver's helmet and may also contain two-way communications, a depth measurement tube, a camera, and hot water to warm the diver's dive suit.
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, an airtight bag attached with a weighted wire and suspended at depth in the diving chamber, is another piece. These tools will allow the diver to lift heavy objects from the bottom of the ocean and use them as a float when they are filled with air. A shot line allows decompression divers, who are able to navigate to surface areas and do a stop at safe places, to use.
