The TracBack function on the Garmin Fenix 3 is your guarantee to never get lost again. Not ever. If I had the Garmin Fenix 3 for the Grand Raid trail race in Reunion Island, I would not have had to run for 19 hours after getting lost in the mountains. The TracBack navigational aid would have directed me back onto the course in a matter of minutes. It is especially usefull if you want to explore unmarked terrain, dense forrestation, rocky mazes and other sections that could get you lost. I got quite disorientated in some cities in Europe while trying to squeeze in a run, and even then it would have been a great help to get me back to my hotel.
The moment you realize you might be lost, simply press stop, scroll down to TracBack and hit start. You’ll get a map that will guide you back, plus additional windows relaying information like estimated time of arrival, distance remaining and how much you are off course. This is but one of the great navigational features of the Fenix 3. Go check it out and never get lost again. You can even use it to find your car in the shopping mall parking lot!
