You may or may not have cell phone service, but with the BackTrack Mini Rechargeable GPS Navigator from Bushnell, you will know where you are, even deep in the backcountry. This compact GPS unit will run for 24 hours per charge and shows compass direction and GPS coordinates, along with time, temperature, elevation, and barometric pressure. The unit also shows your route on an on-screen map and allows you to save, name, and date waypoints. Use Bluetooth to pair with the Bushnell Connect app on your phone, tablet, or computer to save trips and waypoints to the library and view trips overlaid on the app's map. You can share your saved trips from the app by email or text. The app also allows for firmware updates. A tether loop and carabiner-style clip make it easy to hang the BackTrack on clothing or gear.
