Before there were GPS locators, there were these things called maps that folded in confounding ways and had curvy lines for roads and trails. Figuring distance was anyone’s guess. With this ingenious device you simply set the map scale and roll along the path to figure the distance. Invaluable for the intrepid traveller or mapophile. You'd be surprised how popular this product has become since the advent of online mapping.
