SilvaForecaster 610 Compass and Thermometer - Fuchsia

Weight for FOB without ring is 13.2 grams or 0.46 ozWeight for ring is 1.7 grams or 0.06 ozFOB size 2.4" x 1.75" or 6.1 cm x 4.5 cmCompass diameter 1.34" or 3.4 cmRing diameter 0.95" or 2.4 cmCompass red hand points North and is easy to read. Good number separation can be read reliably to 15 degrees (5 degrees if interpolated). Movement is smooth due to liquid fill but must be maintained flat to operate. Unfortunately pointed end of FOB is aligned South. Windchill chart on the back is a nice touch and Temperature reading is consistent with my other outdoor devices. Liquid is red, probably alcohol based.I anticipated this to be smaller but I am happy with the size for practical use and overall readability.

This was for the back of the wifes sled, she loves the color. Well made and accurate, pretty easy to read and it stands up to some rugged use. Price was OK considering the product.

Color is really nice, does the job perfectly, I have it attached to my backpack I take it everywhere. Been traveling around the US with it. Absolutely love it!
