The 314cm avalanche probe is a durable tool ideal for avalanche rescue. It's a probe used to search for buried victims when encountering an avalanche in the mountains. It uses a 11mm diameter 7001 aluminum alloy pole. It combines lightness and strength, and can be used even in hard snow. The total length is 314cm, and the pipes are color-coded every 40cm to measure depth. The inner wire is made of rust-resistant stainless steel. It is coated with resin for protection. It has been stored at home without being used since purchase. It has only been opened once for photography. - Model Name: Avalanche Probe 314cm - Color: Red/Blue - Size: 314cm Thank you for viewing.
