Brunton Axis Pocket Transit

Unless you're a geologist, odds are you won't have a serious need for the Brunton Axis Pocket Transit — but that doesn't mean you won't want it. With a rare earth magnet mounted on a sapphire jewel suspension, the built-in compass is no joke, and would be handy for any outdoorsman. But its the dual 360-degree axis, hollow hinge design that makes it useful for scientists, letting them accurately measure planes, lines, and vertical angles with ease. It also packs an on-board level, a needle locking mechanism, a hollow sighting tube, and has a waterproof, rugged anodized aluminum build.
