Technical diving requires divers to use a variety equipment. Backplates with a harness, for instance, are made of stainless steel, carbon fiber, or aluminum. Diver knives, lights and safety buoys are just a few of the technical gear available. These items can be used to ensure safety and comfort when 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, which allow divers to monitor the level of air in their cylinders, are also important. Dry suits are essential for long-duration dives and provide a layer of insulation to the wearer. A slate, compass and delayed surface buoy are all important diving equipment. A decompression trapeze can help divers maintain correct depth during in-water decompression stops. It is possible to also transport the equipment using a liftbag.
Other equipment used by technical divers includes a full face mask that covers the diver's nose, mouth, and eyes. 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 is a connection to a shot weight that gives a diver a point of reference for their descent. A buddyline is used to connect two divers in the sea and prevent them from becoming 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 by ice divers
Divers using ice diving equipment use multiple types of equipment to ensure safety. They generally use two-stage regulators. Divers can easily switch between the two, without having to purchase a second tank. The diver can simply attach the second-stage regulator to the broken first-stage regulator if it breaks. Ice divers frequently use double tanks which offer redundant air delivery and 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 line can reach 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.
Before ice diving, the team must prepare the area and cut a hole in the ice. 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
Special equipment is used by decompression divers when they're underwater. The multigas dive computer tracks decompression requirements, and allows divers to switch between two types of gases in their cylinder. You can also see the remaining air level in the tank with the submersible tension gauge. The dry suit provides insulation and protection during long dives.
A diver can also use equipment that connects directly to a support platform. Divers can use this equipment to adjust the stop depth and monitor their depth. 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. 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 can be used to lift heavy objects off the bottom of an ocean, and act as a floating device when filled with water. A shot line allows decompression divers, who are able to navigate to surface areas and do a stop at safe places, to use.
