Technical diving requires divers to use a variety equipment. For instance, backplates used with a harness are made of aluminum, carbon fiber or stainless steel. 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 may use certain equipment
Technical divers often have more advanced equipment than those who are recreational divers. It can include specialized gear that can be used when conditions are hazardous and sophisticated computers that assist in monitoring their decompression as well as other dive-related data. Multigas dive computers enable divers to control their decompression and change gas blends while diving. Submersible pressure gags are also vital. They help divers check the amount of air in their tanks. For long-duration dives, dry suits provide insulation and are essential. A slate, compass and delayed surface buoy are all important diving equipment. A decompression trapeze can help divers maintain correct depth during in-water decompression stops. It is possible to also transport the equipment using a liftbag.
The technical diver may also use a full mask to cover his nose, mouth, ears, and eyes. The safety harness can be used for lifting the diver out of water. Other items that technical divers may need include a shotline and a buddy line. 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 ties the diver onto a shotline. An underwater marker buoy marks the divers' position to those at the surface.

Equipment used to ice divers
To ensure their safety, divers use multiple types equipment. They generally use two-stage regulators. This allows the diver to switch between the two without the need for a second tank. The diver can simply attach the second-stage regulator to the broken first-stage regulator if it breaks. 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 cord is attached to the diver’s harness. This acts as a communication tool in an emergency. The safety line can run up to 150 feet. The two-person team might use separate lines in some instances. 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 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.
Equipment used by decompression divers
For decompression diving, special equipment is required. Multigas dive computers track divers' decompression needs, and permit them to switch between the different gases in a tank. The submersible pressure indicator shows how much air is left in the cylinder. Decompression divers also use a dry suit to provide insulation for long dives.

In addition to a self-contained breathing device, divers also use equipment that connects to a surface 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 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. The lifting bag is another equipment piece. This bag is attached to an airtight line and suspended in the bottom of the dive chamber. These tools enable the diver to lift heavy items from the bottom and use them as floating objects when they are full. A shot line allows decompression divers, who are able to navigate to surface areas and do a stop at safe places, to use.
