Technical diving requires divers to use a variety equipment. For instance, backplates used with a harness are made of aluminum, carbon fiber or stainless steel. Diver tools such as lights, rebreathers and stage tanks, safety buoys and bailout bottles are all part of technical diving gear. These items are essential for your safety and comfort while you dive.
Technical divers may use certain equipment
Equipment used by technical divers is often more advanced than that used by recreational divers. It can include specialized gear that can be used when conditions are hazardous and sophisticated computers that assist in monitoring their decompression as well as other dive-related data. For instance, multigas dive computers allow divers to change gas blends on the fly and control their decompression time. 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. Other diving equipment includes a slate, compass, and delayed surface marker buoy. 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.
Other equipment used by technical divers includes a full face mask that covers the diver's nose, mouth, and eyes. Safety harnesses can be used in lifting divers out of the sea. Technical divers might also need a buddy line and a shotline. A shotline is a line connected to a shot weight to give a diver a reference point for their descent. A buddy line connects two divers in the water to each other and prevents them from 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
Ice divers use multiple types of equipment for safety reasons. They often use two first stage regulators. The diver can switch between them without having to use a second tank. In the event that the first-stage regulator fails, the diver can easily attach the second stage regulator to the damaged 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 line is clipped to the diver's harness and acts as a communication device in case of an emergency. The safety line can run up to 150 feet. The safety line may be used by two people in certain cases. 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.
The team must prepare the area before ice diving. Although the most common tool for cutting ice is the chainsaw it must be properly used. The hole should be smooth, so as to prevent damage to the equipment or diver. Many ice divers prefer to use triangle-shaped holes for safer entry or exit.
Decompression divers use equipment
Divers who are decompression certified use specialized equipment underwater. Multigas dive computers track divers' decompression needs, and permit them to switch between the different gases in a tank. You can also see the remaining air level in the tank with the submersible tension gauge. Decompression divers also use a dry suit to provide insulation for long dives.
A diver can also use equipment that connects directly to a support platform. Divers can also use this equipment to adjust their stop depth or monitor their depth. The umbilical supplies the breathing gas to the diver's helmet and may also contain two-way communications, a depth measurement tube, a camera, and hot water to warm the diver's dive suit.
Another important piece of equipment used by decompression divers is the jonline, which is a long line that is used to guide the diver during a search and 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 allow divers to lift heavy objects out of the water and then use them as floats when 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.
