Divers who are skilled in technical diving will need a wide range of equipment. Backplates, which are used in conjunction with a harness, can be made of stainless steel or carbon fiber. 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 use specific equipment
Technical divers often have more advanced equipment than those who are recreational divers. These equipment can be used under hazardous conditions. They also have sophisticated computers that allow them to 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 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. 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. It is possible to also transport the equipment using a liftbag.
The technical diver may also use a full mask to cover his nose, mouth, ears, and eyes. The safety harness can be used for lifting the diver out of water. Other items that technical divers may need include a shotline and a buddy line. A shotline is a line connected to a shot weight to give a diver a reference point 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
Safety reasons make it possible for ice divers to use different types of equipment. They often use two first 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 often use double tanks, which provide redundant air delivery systems and air supplies.
It is essential that you have support personnel available while 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 line can be as long as 150 feet. In some cases, the two-person team may use separate lines. If the diver is not able to reach them, the line tenders will need to wear 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. It is important to make the hole smooth so that there are no injuries to equipment or divers. Many ice divers opt to cut triangle-shaped openings, which offer safer entry and exit.
Equipment used by decompression divers
Special equipment is used by decompression divers when they're underwater. Multigas dive computers are used to track decompression needs and allow divers to switch between different types of gas in a cylinder. The submersible pressure indicator shows how much air is left in the cylinder. Another equipment used by decompression divers is a drysuit, which provides insulation during long diving.
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 supplies the diving gas to the helmet. It can also include two-way communications, depth measurement tubes, cameras, hot water, and hot water for warming the dive suit.
A jonline, a long-lined instrument used by divers to aid in their search and work sessions, is an important piece. A lifting bag is another important piece of equipment. This is an airtight bag which is attached to a heavy line and suspended at bottom of diving chamber. 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.
