Divers who are skilled in technical diving will need a wide range of equipment. Backplates with a harness, for instance, are made of stainless steel, carbon fiber, or aluminum. Diver tools include lights, rebreathers (stage tanks), safety buoys, and rescue bottles. These items will ensure that you are safe and comfortable while diving.
Technical divers use equipment
Technical divers use more sophisticated equipment than 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 enable divers to control their decompression and change gas blends while diving. Submersible gauges are an essential tool for divers. These gauges allow them to see how much air they have and help them monitor their cylinders. 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. The equipment can be carried in a lift bag.
A full face mask is used by technical divers to cover the nose, mouth and eyes. The safety harness can be used for lifting the diver out of 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 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 by ice divers
Divers using ice diving equipment use multiple types of equipment to ensure safety. They typically use two first-stage regulators. This allows them to switch between the regulators without the need of 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. Ice divers frequently use double tanks which offer redundant air delivery and supplies.
Support personnel must always be on hand for ice divers. The safety line attaches to the diver’s harness and serves as a communication device in an emergency. The safety line can run up to 150 feet. The safety line may be used by two people in certain cases. 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 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 opt to cut triangle-shaped openings, which offer safer entry and exit.
Equipment used by decompression divers
Divers who are decompression certified use specialized equipment 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.
Divers can use equipment that connects with a surface support platform in addition to their self-contained breathing apparatus. Divers can adjust their stop depth, monitor their depth, and many other underwater tasks with this equipment. 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.
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 is another equipment piece. This bag is attached to an airtight line and suspended in the bottom of the dive chamber. These tools enable the diver to lift heavy items from the bottom and use them as floating objects when they are full. Decompression divers also use a shot line, which is made up of a weight and line that allows them to navigate to the surface and perform a decompression stop at a safe place.
