Technical diving requires a variety of different equipment. Backplates with a harness, for instance, are made of stainless steel, carbon fiber, or aluminum. Diver gear that isn't technical includes lights, rebreathers stage tanks, safety boss buoys, bailout bottles, and dive knives. These items are used to ensure your safety and comfort while diving.
Technical divers often use the following 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. Dry suits provide insulation for long-duration dives. 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. You can also use a lift bag to transport the equipment.
A full face mask is used by technical divers to cover the nose, mouth and eyes. Safety harnesses are also important as they can be used to lift divers 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 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 to ice divers
Divers using ice diving equipment use multiple types of equipment to ensure safety. They typically use two first-stage regulators. The diver can switch between them without having to use a second tank. The diver can simply attach the second-stage regulator to the broken first-stage regulator if it breaks. Double tanks, which are redundant air supply systems and air delivery systems for ice divers, are common.
Support personnel must always be on hand for ice divers. The safety cord is attached to the diver’s harness. This acts as a communication tool in an emergency. The safety line can reach up to 150 feet. The safety line may be used by two people in certain cases. If the diver is separated from the line tenders, they may have to be covered in thermal protection.
Before going ice diving, teams must prepare the area by cutting a hole in the Ice. The most common tool used for cutting the ice is a chainsaw. However, it should be used carefully. To prevent injury to equipment or divers, the hole must be smooth. Many ice divers choose to cut triangle-shaped holes, which provide a safer entry and exit.
Equipment used by divers for decompression
For decompression diving, special equipment is required. Multigas dive computers are used to track decompression needs and allow divers to switch between different types of gas in a cylinder. Also included is a submersible gauge to display the air remaining in the cylinder. Other equipment used by decompression divers includes a dry suit, which provides insulation during long dives.
A diver can also use equipment that connects directly to a support platform. This equipment enables divers to perform a variety of underwater tasks, such as adjusting the stop depth or monitoring their depth. 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.
The jonline, another piece of equipment decompression divers need to use, is a very important tool. It is a long straight line used to guide divers during search and work sessions. The lifting bag, an airtight bag attached with a weighted wire and suspended at depth in the diving chamber, is another piece. 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.
