Learn how to use comprehensive navigation and tracking functionalities that guide you on and off the beaten track. fenix’s built-in sensors provide information on heading, elevation and weather changes. It records a GPS track log, creating a “bread crumb trail” as you move. It also allows you to mark locations, such as a start/finish line, course checkpoint, or a campsite, vehicle or other point of interest. With f?nix 3, you can create and follow courses, mark up to 1,000 locations and store up to 10,000 track points and navigate to them.
