Technical diving requires divers to use a variety 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 use specific 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, for example, allow divers to adjust gas mixtures and control decompression time on the fly. Submersible pressure gags are also vital. They help divers check the amount of air in their tanks. Dry suits are important for long-duration diving and offer 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. A lift bag is also used to carry the equipment.
Other equipment used by technical divers includes a full face mask that covers the diver's nose, mouth, and eyes. The safety harness can be used for lifting the diver out of water. A buddy line or shotline is another item technical divers may require. 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 tethers the diver to a shotline, and a surface marker buoy indicates the position of the divers to people at the surface.
Equipment used for ice divers
Ice divers use multiple types of equipment for safety reasons. They generally use two-stage regulators. This allows the diver to switch between the two without the need for a second tank. To replace the first-stage regulator that has failed, the diver can grab the second-stage one and attach it to its working counterpart. Ice divers frequently use double tanks which offer redundant air delivery and supplies.
Support personnel must be accessible above the ice when ice diving. The safety cord is attached to the diver’s harness. This acts as a communication tool in an emergency. The safety rope can reach 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.
The team must prepare their area and cut a hole through the ice before they can go ice diving. The most common tool used for cutting the ice is a chainsaw. However, it should be used carefully. The hole should be smooth, so as to prevent damage to the equipment or diver. Many ice divers prefer to make triangle-shaped holes. This allows for safer entry and exit.
Decompression divers use equipment
When diving underwater, decompression divers need to use special equipment. Multigas dive computers track divers' decompression needs, and permit them to switch between the different gases in a tank. 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. Divers can adjust their stop depth, monitor their depth, and many other underwater tasks with this equipment. 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.
The jonline is another important piece of equipment for decompression divers. It is a long, flexible line that guides the diver throughout a search or work session. The lifting bag, an airtight bag attached with a weighted wire and suspended at depth in the diving chamber, is another piece. 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 is also used by decompression divers. It is composed of a weighted line and a line that allows them navigate to the surface and make a stop at a safe location.
