Features
The Lexan polycarbonate PC Crystal Card provides a surface to analyze/classify snow grains and also has a slope index, which allows you to determine slope angles from a topographical map. Snow crystals placed on the card become recognizable and sizable. 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. Comes included with the BCA Snow Study Kit.
Includes metric ruler, 2 mm grid, and beveled edge. Protective clear coat snow crystal and snowpit 'cheat sheets'. Translucent blue and graphic-free section enable improved clarity for grain type classification. Lexan PC material does not conduct heat, which keeps the crystals from melting.
- Weight: 1.2oz / 35g.
- Dimensions: 6" x 4" / 15cm x 10cm.
- Materials: Lexan polycarbonate.

AI FAQs
AI generated FAQs about the Polycarb Crystal Card
What can this tool actually tell me about avalanche risk that I need to know?
This card lets you analyze and classify snow grains and determine slope angles from a topographical map. You can use those observations as part of snowpack analysis in the field.
How heavy is this, and will it fit in my pack without taking up too much space?
This card weighs 1.2 oz (35 g) and measures 6 x 4 inches (15 x 10 cm). Its slim, compact dimensions make it easy to carry with your snow-study gear in the field.
What are the limits of what this tool can tell me about snow stability?
This card is suited to snow-grain classification, crystal sizing, and determining slope angles from a topographical map. It is not a direct snow-stability determination tool; its stated role is to provide snow-study observations.
What makes this tool different from other snow study tools I might buy?
This translucent blue Lexan polycarbonate card has a non-heat-conducting surface, a 2 mm grid, a metric ruler, a slope index, and a graphic-free section for clearer grain-type classification. Compared with the Aluminum Crystal Card, it absorbs less radiation, helping you study snow crystals longer and more accurately in sunnier conditions.
