Getting lost in the woods or the desert is no fun. Make sure you have your backpacking essentials, including a map and the Silva Explorer 203 Compass. An ergonomically designed base plate fits comfortably in your hand while you read your map using both 1:24,000 and 1:62,500 direct reading scales. The Explorer 203 extended base plate has inch and 1/10-mile direct reading scales that meet U.S.G.S. standards and weights in a just one ounce, leaving you no reason to leave your compass behind.
