What type of shovel is recommended for use in avalanche rescue?

A metal expandable shovel is recommended for use in avalanche rescue due to its durability and efficiency in breaking through snow layers. During an avalanche rescue operation, rescuers may encounter compacted snow, ice, and debris, which a sturdy metal shovel can handle much better than lighter materials. The expandable feature allows for easy transportation and storage while providing the capability to extend and adapt when needed to efficiently move snow.

This type of shovel is designed specifically for the demands of backcountry use, enabling rescuers to quickly and effectively excavate buried victims. Additionally, metal shovels typically have sharper edges which can penetrate through hard snow crusts, providing the necessary strength and functionality that are critical in urgent rescue situations.
