Smartphones are amazing things. But if youíre miles deep in the wild, away from coverage and out of juice, you're going to need a carrier pigeonís sense of direction. Or better yet, one of these. The Heritage Lensatic Compass is built in the tried-and-true construction that navigatorís used a century ago. Sturdy, shock-resistant brass casing folds down compactly, and an adjustable lens gives crystal clear reading from the liquid filled compass. Made with one welcome modern touch - glow-in-the-dark cardinal letters for excellent nighttime visibility.
