Silva Forecaster 610
Here's what other sites are saying:
Living up to its name, the liquid-filled Silva Forecaster 610 Compass not only provides you with direction but with a thermometer and wind chill chart imprint as well. The five-degree graduation allows you to check direction without breaking stride, and the non-magnetic brass ring easily clips to your jacket zipper to ensure you're never lost without it.
An accurate easy-to-read compass/thermometer combo. It works as a key chain or zipper pull. Fixed with 5 compass graduations with wind chill table conveniently located on the back of compass.
