BCA Polycarbonate Crystal Card

The versatile and informational card that will take up barely any space. For studying snow crystals in the backcountry.

The BCA polycarbonate crystal card provides a surface to analyze/classify snow grains. Snow crystals placed on the card become recognizable and sizable. Ideal for sunnier climates, the BCA polycarbonate 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.
