Divers who are skilled in technical diving will need a wide range of equipment. Backplates that attach to a harness are made from aluminum, carbon fiber, and stainless steel. Other technical dive gear includes dive knives, lights, rebreathers, stage tanks, safety buoys, and bailout bottles. These items can be used to ensure safety and comfort when diving.
Technical divers often use the following equipment:
Technical divers often use more advanced equipment than recreational divers. It includes specialized gear, which can be used in hazardous conditions, and sophisticated computers that help them monitor their decompression and other dive-related data. Multigas dive computers, for example, allow divers to adjust gas mixtures and control decompression time on the fly. Submersible pressure meters are essential for divers. They allow them to check how much air is left in their cylinders. Dry suits provide insulation for long-duration dives. 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. The equipment can be carried in a lift bag.
Other equipment used by technical divers includes a full face mask that covers the diver's nose, mouth, and eyes. It can also be used to lift the diver from the water. A buddy line and shotline are two other items technical divers might need. A shotline connects to a shotweight to provide a reference point to the diver for their descent. A buddy line is a connection between two divers in the water that prevents them becoming separated. A jonline attaches the diver and to a shotline. A surface marker buoy shows the position of divers to the people at the top.
Equipment used by ice divers
Ice divers use multiple types of equipment for safety reasons. Two first-stage regulators are used by ice divers. 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. Ice divers often use double tanks, which provide redundant air delivery systems and air supplies.
Support personnel must be accessible above the ice when ice diving. 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 rope can reach 150 feet. Sometimes the two-person line tenders may use separate lines. If the diver is separated from the line tenders, they may have to be covered in thermal protection.
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. 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.
Decompression divers' equipment
Special equipment is used by decompression divers when they're underwater. The multigas dive computer tracks decompression requirements, and allows divers to switch between two types of gases in their 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.
Apart from a self-contained breath device, divers can also use equipment which connects to a platform for support. Divers can perform many underwater tasks using this equipment, including adjusting their stop depth or monitoring it. 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.
A jonline, a long-lined instrument used by divers to aid in their search and work sessions, is an important piece. 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 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.
