Card - analyser of snow structure BCA Aluminum Crystal Card

BCA Crystal Card - Crystal cards are crucial for analysing the structure of the snowpack, as the difference between a weak layer and a well-bonded layer does not look very noticeable to the naked eye, but the crystals placed on the cards become instantly recognisable and visible.
The Crystal Card has a grid with 1, 2 and 3 mm increments for scaling.
The instructions on the back detail the basic methods and techniques for building a snowbank and provide information on snowflake types.
The printed slope index helps you determine the angle of the slope on the topographic map.
The large size of 15 x 10 cm (6 x 4 in) is ideal for use as a bookmark.
BCA Crystal cards can also be used as tiny plates in winter camp or as throwing stars in case of bear attacks.
BCA cards are available in two versions: polycarbonate and aluminium:
- The polycarbonate version does not absorb as much solar radiation and does not conduct heat away from your hands, which means you can analyse crystals for longer before they melt in the sun;
- the aluminium version is slightly more durable but slightly heavier (40 g vs. 35 g).
With the aluminum card version, you can expect durability and long term usage. This small yet very informational tool will take your snow safety skills to a new level.

- Size, cm:  15 x 10 cm (6 x 4 in)
