lost with the Foretrex 401. Foretrex keeps track of your path and displays it as
a dotted trail on the screen. Just turn on Foretrex's TracBackĀ® feature, and you

altitude with Foretrex 401's electronic compass and barometric altimeter. You
can save locations in memory as waypoints, so you can always find your way back
to any important place, like your campsite or vehicle. And with up to 17 hours

it back.
Track Your Data

provides other helpful information, including a trip computer, sunrise/sunset
times and hunting and fishing information. For even more data, connect Foretrex
401 to a wireless accessory, such as a heart rate monitor, cadence sensor, or
clip it on your bike with the accessory bike mount. To keep track of your trip,
connect your Foretrex to your PC or Mac with USB to store your waypoints, routes
and tracks on your computer. You can also share waypoints, routes and tracks
