If you have a decent smartphone, chances are it’s got a compass app in there, tucked away in your “apps I don’t use but will probably come in handy later” folder. It’s one tap away, though most of us barely use it.

As such, it’s hard to see why anyone would need an actual standalone compass nowadays.

But imagine you’re hiking alone in the Appalachian Trail. Your phone just died. You don’t have anything — no compass, no GPS, nothing. And you desperately want to get home. It’s getting dark. Really dark.

That’s where Brunton’s TruArc Luminous Compass comes in. It’s got an analog compass that’ll let you stay on course. But not only that, it also comes with a built-in luminous light that’ll come in handy if you find yourself in low-light situations. It features am Azimuth, North pointing needle, a vial bottom, an arrow of direction, and a sight that will keep glowing for up to eight hours. The TruArc 15 even has a map magnifier, a sighting mirror, a bubble level, and a triple clinometers system for accurate information. There’s an included lanyard as well. That’s to make sure you don’t misplace the compass. The whole thing weighs just 3.2 ounces and measures 4 x 2.5 x 0.6 inches, so it’s easy to lose.

It’s a pretty excellent entry-level compass for all you amateur hikers out there, and Brunton’s TruArc Global Needle system, plus Ever-North rare earth magnets, make it a trusted companion for all your adventures in the wilderness. Never be lost with the TruArc 15 Luminous Compass, yours for just $70.
