Technical diving demands a variety of equipment. Backplates, which are used in conjunction with a harness, can be made of stainless steel or carbon fiber. Diver gear that isn't technical includes lights, rebreathers stage tanks, safety boss buoys, bailout bottles, and dive knives. These items are used to ensure your safety and comfort while diving.
Technical divers often use the following equipment:
Technical divers use more sophisticated 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 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 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. To transport the equipment, a lift bag can also be used.
Technical divers also use a full-face mask, which covers the nose, mouth, eyes, and ears. Safety harnesses can be used in lifting divers out of the sea. A buddy line or shotline is another item technical divers may require. A shotline is a connection to a shot weight that gives a diver a point of reference for their descent. A buddy line connects two divers in water to prevent them from getting 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 for ice divers
Safety reasons make it possible for ice divers to use different types of equipment. They generally use two-stage regulators. This allows the diver to switch between the two without the need for a second tank. The diver can simply attach the second-stage regulator to the broken first-stage regulator if it breaks. Double tanks, which are redundant air supply systems and air delivery systems for ice divers, are common.
Support personnel must always be on hand for ice divers. The safety rope is fastened to the harness of the diver and acts as an emergency communication device. The safety rope can reach 150 feet. The two-person team might use separate lines in some instances. The line tenders must be dressed in thermal protection and may need to enter the water if the diver becomes separated from them.
Before ice diving, the team must prepare the area and cut a hole in the ice. The most commonly used tool to cut the ice is the chainsaw, but it must always be used correctly. To prevent injury to equipment or divers, the hole must be smooth. Many ice divers prefer to make triangle-shaped holes. This allows for safer entry and exit.
Equipment used for decompression divers
For decompression diving, special equipment is required. 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. The submersible pressure indicator shows how much air is left in the cylinder. Other equipment used by decompression divers includes a dry suit, which provides insulation during long dives.
Divers use equipment that connects and is independent of their breathing device. Divers can also use this equipment to adjust their stop depth or monitor their depth. The umbilical provides the breathing gas for the diver's helmet. It may also contain two way communications, a depth measure tube, a camera, or hot water to warm his 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. A shot line allows decompression divers, who are able to navigate to surface areas and do a stop at safe places, to use.
