Divers who are skilled in technical diving will need a wide range of equipment. For example, backplates for harnesses are made from stainless steel, carbon fibre, or aluminum. Diver knives, lights and safety buoys are just a few of the technical gear available. These items can be used to ensure safety and comfort when diving.
Technical divers often use the following equipment:
Technical divers use more sophisticated equipment than recreational divers. This equipment includes sophisticated gear that can be used in dangerous conditions and computers that monitor and record their dive data and decompression. Multigas dive computers, for example, allow divers to adjust gas mixtures and control decompression time on the fly. Submersible pressure gauges are also essential, and they help divers monitor how much air they have in their cylinders. Dry suits are necessary for long-duration divers and provide insulation. A slate, compass and delayed surface buoy are all important 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.
The technical diver may also use a full mask to cover his nose, mouth, ears, 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 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 buddy line attaches the diver on a shotline. A surface marker buoy is used to indicate the divers' location to others.
Equipment used by Ice Divers
Safety reasons make it possible for ice divers to use different types of equipment. 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 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 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. The most commonly used tool to cut the ice is the chainsaw, but it must always be used correctly. It is important to make the hole smooth so that there are no injuries to equipment or divers. Many ice divers prefer to use triangle-shaped holes for safer entry or exit.
Equipment used by decompression divers
Special equipment is used by decompression divers when they're underwater. This equipment includes a multigas dive computer, which tracks decompression requirements and allows the diver to switch between the two types of gases in a cylinder. The submersible pressure indicator shows how much air is left in the cylinder. The dry suit provides insulation and protection 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 breathing gas to the helmet of the diver. It may also have two-way communication, a depth measuring tube, a camera and hot water to warm the 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 piece of equipment. It is an airtight bag that is attached to a weighted rope and suspended at the bottom. These tools are used by divers to lift heavy objects from deep seawater and use them for floats once they have been 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.
