The Silva Forecaster is a great choice for those days spent exploring the outdoors. This combination of a thermometer and a compass makes the product a highly versatile one. Adding to its versatility, it can either be used as a key ring or a zipper pull which makes transporting it a breeze. Since the key ring comes from non-magnetic brass, it doesn't interfere with the workings of your compass. The 5 degree graduations make sure that you can read the temperature easily and with a great deal of accuracy. A wind chill chart imprint on the back lets you keep track of the weather so you're fully equipped to deal with changing situations. Map your way with ease as the liquid filled capsule aids the compass in settling fast and protects it from shock. The Silva Forecaster is your guide for every expedition.
