Divers must have a variety in equipment for technical diving. 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.
Equipment used by technical divers
Technical divers often have more advanced equipment than those who are 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 computer allows divers to modify gas blends in real time and regulate their decompression. Submersible pressure gags are also vital. They help divers check the amount of air in their tanks. Dry suits are necessary for long-duration divers and provide insulation. Another diving equipment is a slate, compasses, 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.
A full face mask is used by technical divers to cover the nose, mouth and eyes. A safety harness is also essential, as it can be used to lift the diver out of the water. A buddy line, shotline, and other equipment are also important for technical divers. A shotline is a connection to a shot weight that gives a diver a point of reference for their descent. A buddy line is a connection between two divers in the water that prevents them becoming separated. A jonline ties the diver onto a shotline. An underwater marker buoy marks the divers' position to those at the surface.
Equipment used by ice divers
Divers using ice diving equipment use multiple types of equipment to ensure safety. They usually use two first-stage regulators. This allows them to switch between the regulators without the need of 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. 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 rope is fastened to the harness of the diver and acts as an emergency communication device. The safety line can be as long as 150 feet. Sometimes, the two-person team may have separate lines. 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.
Before going ice diving, teams must prepare the area by cutting a hole in the Ice. A chainsaw is the most common tool used to cut the ice, but it must be used properly. To avoid damage to equipment and divers, the hole should be smooth. Many ice divers use triangle-shaped holes to provide safer entry and exit.
Decompression divers' equipment
For decompression diving, special equipment is required. The multigas dive computer tracks decompression requirements, and allows divers to switch between two types of gases in their cylinder. A submersible pressure gauge is available to show the remaining air in a cylinder. Decompression divers also use a dry suit to provide insulation for long dives.
Divers use equipment that connects and is independent of their breathing device. Divers can perform many underwater tasks using this equipment, including adjusting their stop depth or monitoring it. The umbilical supplies oxygen to the diver's head and can also be used to communicate with the other side.
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. 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.
