Navigating a Saved Track You can save your track log to use later as a TracBack, which reduces your track log into a route with up to 300 turns. When initiated, a TracBack route leads you back to the oldest stored track log point. It is a good idea to clear the existing track log before you start your current trip. Also, you must save an active track log before you can navigate it as a TracBack. To start a TracBack using the Nav key: 1. Press Nav, highlight Navigate Track, and press Enter. 2. Highlight the track you want to navigate, and press Enter. Selecting a saved track. 3. Select the point you want to navigate (TracBack) to, and press Enter. Marine Mode > Managing Your Tracks TracBack Tips When a TracBack is initiated, the GPSMAP 276C divides the track into segments called legs. Up to 300 temporary turns are created to mark the most significant features of the track in order to duplicate your exact path as closely as possible. To get the most out of the TracBack feature, remember these tips: • Always clear the track log at the point that which you want to go back (such as a dock or campsite). • The Record Mode option on the Active Track tab must be set to Fill or Wrap. • If the track log Interval option on the Active tab is set to the Time option, the route might not navigate your exact path (keep the interval set to Resolution for best performance). • If the receiver is turned off or satellite coverage is lost during your trip, TracBack draws a straight line between any point where coverage was lost and where it resumed. • If the changes in distance and direction of your track are too complex, 300 waypoints might not mark your path accurately. The receiver then uses the most significant points of your track so there are fewer changes in direction. GPSMAP 276C Owner's Manual 37
