Technical diving requires divers to use a variety equipment. Backplates that attach to a harness are made from aluminum, carbon fiber, and 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 used to ensure your safety and comfort while diving.
Technical divers may use certain equipment
Technical divers often use more advanced 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. 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. For long-duration dives, dry suits provide insulation and are essential. You can also use a compass, slate, or delayed surface marker buoy as diving equipment. A decompression trapeze can help divers maintain correct depth during in-water decompression stops. A lift bag is also used to carry the equipment.
A full face mask is used by technical divers to cover the nose, mouth and eyes. It can also be used to lift the diver from the water. Other items that technical divers may need include a shotline and a buddy line. A shotline can be a line attached to a gun weight to give divers a point of reference during 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
Safety reasons make it possible for ice divers to use different types of equipment. They usually use two first-stage regulators. It allows divers to swap between the two regulators without needing a second tank. The diver can simply attach the second-stage regulator to the broken first-stage regulator if it breaks. 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 cord is attached to the diver’s harness. This acts as a communication tool in an emergency. The safety rope can reach 150 feet. Sometimes the two-person line tenders may use separate lines. If the diver is separated from the line tenders, they may have to be covered in thermal protection.
Before ice diving, the team must prepare the area and cut a hole in the ice. While the most common tool to cut ice is the chainsaw (but it must be used with care), it is still very useful. 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' equipment
When diving underwater, decompression divers need to use special equipment. 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. You can also see the remaining air level in the tank with the submersible tension gauge. A dry suit is another equipment that decompression divers use. It provides insulation during long dives.
In addition to a self-contained breathing device, divers also use equipment that connects to a surface support platform. This equipment enables divers to perform a variety of underwater tasks, such as adjusting the stop depth or monitoring 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.
The jonline, another piece of equipment decompression divers need to use, is a very important tool. It is a long straight line used to guide divers during search and work sessions. 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. 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.
