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. 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
Equipment used by technical divers is often more advanced than that used by 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 enable divers to control their decompression and change gas blends while diving. Submersible pressure gauges, which allow divers to monitor the level of air in their cylinders, are also important. Dry suits are essential for long-duration dives and provide a layer of insulation to the wearer. 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. 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. A safety harness is also essential, as it can be used to lift the diver out of the water. A buddy line or shotline is another item technical divers may require. A shotline is a connection to a shot weight that gives a diver a point of reference 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 to ice divers
Safety reasons make it possible for ice divers to use different types of equipment. They generally use two-stage regulators. The diver can switch between them without having to use a second tank. If the first-stage regulator breaks, the diver can just pick up the second-stage regulator and attach it to the working first-stage regulator. Double tanks are used by ice divers to provide redundant air supply and delivery systems.
It is essential that you have support personnel available while ice diving. The safety line attaches to the diver’s harness and serves as a communication device in an emergency. The safety line can be as long as 150 feet. Sometimes, the two-person team may have 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. Although the most common tool for cutting ice is the chainsaw it must be properly used. The hole should be smooth, so as to prevent damage to the equipment or diver. Many ice divers opt to cut triangle-shaped openings, which offer safer entry and exit.
Equipment used for 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. There is also a submersible pressure gauge that shows the remaining air in the cylinder. Decompression divers also use a dry suit to provide insulation for long dives.
A diver can also use equipment that connects directly to a support platform. 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.
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. 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 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.
