After many requests, AR Navigation Supplies has just released the first volume of its Table Top Adventure Race and Navigation Challenge books. Think of this book as Sudoku for navigators. The book is designed to allow navigators to practice and improve their navigation skills while at home, in the office or traveling. All you need is a Compass, UTM tool and a pencil and you're ready for a table top adventure that will test your skills and improve your navigation regardless of your current expertise. The book contains 12 separate navigation challenges covering 8 different states from New York to California using USGS 1:24,000 scale maps. The goal is to find your way around each map by following the rules of travel, plotting the route and answering the questions presented for each CP. If you get lost there is a help section that will guide you through the common navigation techniques and adventure racing terms to get you back on track. Challenge your friends to the table top competition and see who should be the team navigator at the next race, it may surprise you.
