What are the ice diving skills?

Diving on ice requires high diving ability, because diving on ice is really full of challenges and dangers. Today, Bian Xiao will tell you some skills you need to master in ice diving. Interested friends can learn about this information.

Breaking the ice, breaking the ice, I mean to cut an ice diving channel leading to the water inlet in the ice. Choose a certain thickness of ice to dive on the ice to ensure the safety of people on the ice. First of all, we should use hand-made ice drills to cut a certain number of small holes in the ice layer, which are triangular. Then use a chainsaw to cut along the triangle of the hole made by the hand-operated ice drill, and finally drive a snowmobile to drag a whole piece of ice out of the water. In this way, a water inlet can be skillfully and safely carved on the glacier.

Strict diving companion system Ice diving, like routine diving, must also have a diving companion system, in which the ice safety officer is an indispensable role in ice diving. We divide this part into novice and experienced ice divers.

The first condition is that three people are needed for ice diving in the ice cave. Novice divers are connected by ropes, which are divided into 1 and No.2 divers. The diver 1 who enters the water is responsible for communicating with the safety officer on the ground in rope language, sending different messages through different rope languages and communicating with the safety officer on the ground in time. Diver No.2 is relatively free and can wholeheartedly carry out underwater sightseeing, underwater shooting and other activities. In order to be foolproof, the ice diving instructor will have a separate rope to enter the water together to ensure safety.

Safety rope = life rope The ice cave was dug in a relatively closed space. An absolutely indispensable tool is the "safety rope", which has never been used by the BBC photography team. But they have fixtures. They cut many holes in the ice (in order to find the exit without safety ropes). Their diving skills are excellent. For ordinary divers, at least 100 ice dives have never been done, so use safety ropes. The "safety rope" plays a key role, which allows us to find the entrance and exit accurately without getting lost underwater. At the same time, through the "rope language" communication with the ice safety officer, you can get the help of the safety officer in an emergency.

Generally, a safety rope with moderate thickness and weight, 8- 14 mm, is used. Too thin safety rope is inconvenient to take and easy to slide down. Too thick weight is easy to be overweight, causing a burden. A rope can tie up two divers at most.

Breathing skills In order to prevent the secondary head from freezing in a cold environment, the first breath must be taken underwater. In addition, we must grasp the rhythm of underwater breathing. Because the air flow is inversely proportional to the temperature of the primary head, remember not to breathe excessively, or use the secondary head, BC inflatable tube and dry clothes inflatable tube at the same time.

Okay, do you understand? Be sure to remember these skills. I hope everyone will pay attention to safety and dive smoothly on the ice!
