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 knives, lights and safety buoys are just a few of the technical gear available. These items are used to ensure your safety and comfort while diving.
Technical divers may use certain equipment
Technical divers often use more advanced equipment 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 enable divers to control their decompression and change gas blends while diving. Submersible pressure gauges, which allow divers to monitor the level of air in their cylinders, are also important. 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. The equipment can be carried in a lift bag.
Another equipment technical divers use is a full face mask. This covers the diver's nose and mouth as well as his eyes. A safety harness is also essential, as it can be used to lift the diver out of the water. Other items that technical divers may need include a shotline and a buddy line. A shotline can be a line attached to a gun weight to give divers a point of reference during their descent. A buddyline connects two divers in shallow water to one another and prevents them getting 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
Divers using ice diving equipment use multiple types of equipment to ensure safety. They usually use two first-stage regulators. Divers can easily switch between the two, without having to purchase a second tank. When the first stage regulator is damaged, the diver simply needs to attach the second-stage controller to the broken one. Double tanks, which are redundant air supply systems and air delivery systems for ice divers, are common.
While ice diving, support personnel must be available 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. Sometimes, the two-person team may have separate lines. If the diver is not able to reach them, the line tenders will need to wear thermal protection.
Before ice diving, the team must prepare the area and cut a hole in the ice. A chainsaw is the most common tool used to cut the ice, but it must be used properly. To prevent injury to equipment or divers, the hole must be smooth. Many ice divers prefer to use triangle-shaped holes for safer entry or exit.
Decompression divers use equipment
When diving underwater, decompression divers need to use special equipment. Multigas dive computers, which track decompression requirements and allow the diver to switch among the two types in a container, are part of this equipment. The submersible pressure indicator shows how much air is left in the cylinder. A dry suit is another equipment that decompression divers use. It provides insulation during long dives.
Apart from a self-contained breath device, divers can also use equipment which connects to a platform for support. Divers can also use this equipment to adjust their stop depth or monitor their depth. 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. 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. The shot line is used by decompression divers to help them navigate to and from the surface.
