Technical diving demands a variety of equipment. For instance, backplates used with a harness are made of aluminum, carbon fiber or stainless steel. Diver gear that isn't technical includes lights, rebreathers stage tanks, safety boss buoys, bailout bottles, and dive knives. These items are necessary to ensure your safety while diving.
Technical divers may use certain equipment
Equipment used by technical divers is often more advanced than that used by recreational divers. It may include special gear that can only be used in extreme conditions. Additionally, it includes sophisticated computers that aid them in monitoring their decompression, as well as other data. For instance, multigas dive computers allow divers to change gas blends on the fly and control their decompression time. 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. For long-duration dives, dry suits provide insulation and are essential. 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. The equipment can be carried in a lift bag.
Technical divers also use a full-face mask, which covers the nose, mouth, eyes, and ears. Safety harnesses are also important as they can be used to lift divers out of the water. Technical divers might also need a buddy line and a shotline. A shotline, which is connected to a weight in shot to provide a reference point for a diver's descent, is a line that connects to a shotweight. 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
To ensure their safety, divers use multiple types equipment. They usually use two first-stage regulators. Divers can easily switch between the two, without having to purchase a second tank. If the first-stage regulator breaks, the diver can just pick up the second-stage regulator and attach it to the working first-stage regulator. Ice divers often use double tanks, which provide redundant air delivery systems and air supplies.
Ice diving requires that support personnel be present above the ice. The safety line attaches to the diver’s harness and serves as a communication device in an emergency. The safety line can be as long as 150 feet. Sometimes the two-person line tenders may use separate lines. Line tenders should be wearing thermal protection, and may need to get into the water if they become separated from the diver.
Before going ice diving, teams must prepare the area by cutting a hole in the Ice. 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 prefer to use triangle-shaped holes for safer entry or exit.
Decompression divers use equipment
Special equipment is used by decompression divers when they're underwater. This equipment includes a multigas dive computer, which tracks decompression requirements and allows the diver to switch between the two types of gases in a cylinder. A submersible pressure gauge is available to show the remaining air in a cylinder. 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. Divers can perform many underwater tasks using this equipment, including adjusting their stop depth or monitoring it. The umbilical supplies oxygen to the diver's head and can also be used to communicate with the other side.
Another piece of equipment that decompression divers use is the jonline. This is a long rope that is used to guide the diver in a search and/or work session. 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 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.
