Technical diving requires a variety of different equipment. For instance, backplates used with a harness are made of aluminum, carbon fiber or stainless steel. Diver tools include lights, rebreathers (stage tanks), safety buoys, and rescue bottles. These items are necessary to ensure your safety while diving.
Technical divers use specific 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 important for long-duration diving and offer 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. A safety harness is also essential, as it can be used to lift the diver out of the water. A buddy line and shotline are two other items technical divers might need. 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 buddy line ties the diver to a shotline and a surface marker buoy signals the location of the divers to others at the surface.
Equipment used by ice divers
Safety reasons make it possible for ice divers to use different types of equipment. Two first-stage regulators are used by ice divers. 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.
Support personnel must always be on hand for ice divers. The safety line is clipped to the diver's harness and acts as a communication device in case of an emergency. The safety rope can reach 150 feet. In some cases, the two-person team may use separate lines. 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 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. 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
Decompression divers use specialized equipment when they are underwater. 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. Also included is a submersible gauge to display the air remaining in the cylinder. Another equipment used by decompression divers is a drysuit, which provides insulation during long diving.
A diver can also use equipment that connects directly to a support platform. Divers can perform many underwater tasks using this equipment, including adjusting their stop depth or monitoring it. 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 piece of equipment. It is an airtight bag that is attached to a weighted rope and suspended at the bottom. These tools can be used to lift heavy objects off the bottom of an ocean, and act as a floating device when filled with water. Shot lines are also used by decompression divers. They consist of a weight and a line that allow them to navigate to the surface, and then make a safety stop.
