It’s a combo compass, thermometer, watch and LED light that’s selling at most online retailers from $35-65. It’s only $20 (+ approx. $6 s&h) for one day only from Steep and Cheap, so you’ll have to act fast on this one. Steep and Cheap sells outdoor gear one item or model at a time at usually ridiculously low prices. If it’s not showing at the link http://www.steepandcheap.com/, it’s gone and sold out already.

No guarantees on it’s accuracy, but for twenty bucks it looks pretty cool!
