Getting lost is not an option, and you can feel comfortable knowing that you won't with the Garmin Foretrex GPS Wrist Unit. The unit keeps track of your path, so you can concentrate on making it to the next peak. A dotted trail is recorded on the screen so you can retrace your steps and make it safely back to base camp. It will even save locations of interest. It also includes an electronic compass and altimeter, making it perfect for hikers. The slim navigator fits around your wrist with an adjustable Velcro band so you can keep your hands free for carrying supplies or hacking your way through the jungle. You can quickly see how long your trip is, when sunrise and sunset will be, as well as hunting and fishing information. For additional data, you can connect the Garmin to a wireless accessory which has features like a heart rate monitor and cadence sensor. The device lasts up to 17 hours on AAA batteries.
