Technical diving demands a variety of equipment. Backplates, which are used in conjunction with a harness, can be made of stainless steel or carbon fiber. Diver tools include lights, rebreathers (stage tanks), safety buoys, and rescue bottles. These items are used to ensure your safety and comfort while diving.
Technical divers often use the following equipment:
Technical divers often use equipment that is more advanced 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 are able to allow divers the ability to alter gas blends as they go and also control their decompression times. 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. 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. 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 can be used in lifting divers out of the sea. A buddy line or shotline is another item technical divers may require. A shotline connects to a shotweight to provide a reference point to the diver for their descent. A buddy line connects two divers in water to prevent them from getting 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
For safety reasons, ice divers may use several types of equipment. They often use two first stage regulators. Divers can easily switch between the two, without having to purchase 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.
Ice diving requires that support personnel be present above the ice. The safety line is attached to the diver's harness. It acts as a communication device and a means of communicating with emergency personnel. The safety line can run up to 150 feet. The two-person team might use separate lines in some instances. 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. The most commonly used tool to cut the ice is the chainsaw, but it must always be used correctly. It is important to make the hole smooth so that there are no injuries to equipment or divers. Many ice divers prefer to use triangle-shaped holes for safer entry or exit.
Decompression divers' equipment
Special equipment is used by decompression divers when they're underwater. Multigas dive computers track divers' decompression needs, and permit them to switch between the different gases in a tank. You can also see the remaining air level in the tank with the submersible tension gauge. Other equipment used by decompression divers includes a dry suit, which provides insulation during long dives.

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.
Another important piece of equipment used by decompression divers is the jonline, which is a long line that is used to guide the diver during a search and work session. Another piece of equipment is the lifting bag, which is an airtight bag attached to a weighted line and suspended at the bottom of the 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. Decompression divers also use a shot line, which is made up of a weight and line that allows them to navigate to the surface and perform a decompression stop at a safe place.
