Technical diving requires divers to use a variety equipment. Backplates with a harness, for instance, are made of stainless steel, carbon fiber, or aluminum. Other technical dive gear includes dive knives, lights, rebreathers, stage tanks, safety buoys, and bailout bottles. These items are used to ensure your safety and comfort while diving.
Technical divers use specific equipment
Technical divers often use more advanced equipment than 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. Multigas dive computers enable divers to control their decompression and change gas blends while diving. Submersible pressure gags are also vital. They help divers check the amount of air in their tanks. 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. A lift bag is also used to carry the equipment.
Technical divers also use a full-face mask, which covers the nose, mouth, eyes, and ears. It can also be used to lift the diver from the water. A buddy line or shotline is another item technical divers may require. A shotline can be a line attached to a gun weight to give divers a point of reference during their descent. A buddyline connects two divers in shallow water to one another and prevents them getting separated. A buddy line attaches the diver on a shotline. A surface marker buoy is used to indicate the divers' location to others.
Equipment used for ice divers
Ice divers use multiple types of equipment for safety reasons. They usually use two first-stage regulators. It allows divers to swap between the two regulators without needing 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 frequently use double tanks which offer redundant air delivery and supplies.
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 line can run up to 150 feet. In some cases, the two-person team may use separate lines. If the diver is not able to reach them, the line tenders will need to wear thermal protection.
Before diving, it is important to prepare the area and make a hole in ice. While the most common tool to cut ice is the chainsaw (but it must be used with care), it is still very useful. It is important to make the hole smooth so that there are no injuries to equipment or divers. Many ice divers opt to cut triangle-shaped openings, which offer safer entry and exit.
Equipment used by decompression divers
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. The submersible pressure indicator shows how much air is left in the cylinder. The dry suit provides insulation and protection during long dives.
Divers can use equipment that connects with a surface support platform in addition to their self-contained breathing apparatus. Divers can use this equipment to adjust the stop depth and monitor 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 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 piece of equipment. It is an airtight bag that is attached to a weighted rope and suspended at the bottom. These tools allow divers to lift heavy objects out of the water and then use them as floats when filled with air. The shot line is used by decompression divers to help them navigate to and from the surface.
