Versatile card for studying snow crystals & slope angles

The Lexan polycarbonate PC Crystal Card provides a surface to analyze and classify snow grains and also has a slope index, which allows you to determine slope angles from a topographical map. Ideal for sunnier climates, the PC Crystal Card does not absorb as much radiation as the Aluminum Crystal Card, which allows you to study snow crystals longer and more accurately. This small yet very informational tool will take your snow safety skills to a new level.
