Checking our bearings, making sure.We humans have always navigated through our world: by landmark and water,sun and stars. The technology we employ changes, but wayfinding knowledgedoes not: if you dont understand how to navigate, youre still lost. Thus, theskill to navigate by map and compassneither of which depends on advancedelectronics or batteriesis crucial. Whether exploring a wild mountain rangewhere the only available information is a printed map or the confusion of aforeign city. It can also be fun.Over the years, Silva has become a reliable and trusted navigation partneramong defense forces, expeditions to the remotest parts of the globe, andthe orienteering and adventure racing communities. One reason for this voteof confidence is the Silva 1-2-3 System that enables you to take and walk abearing in an easy and accurate way. The popular system evolves this yearwith colour-coding on the Field 1-2-3 Compass, a new memory tool for botheducational use and the infrequent navigator.Whichever Silva product you choose, the first question is always the same:WHERE ARE YOU GOING?
