Main Menu Using Track Logs The eTrex Venture draws an electronic bread crumb trail on the Map Page as you travel along. This bread crumb trail is the 'Track Log'. The Track Log contains information about points along its path, including time, and position. The eTrex Venture uses this information to allow you to navigate using the saved track. The 'TracBack' feature allows you to return along a traveled path without marking any waypoints. When you are ready to return to where you started, the eTrex Venture takes you back by following the 'Track Log' that you left behind. You can save a total of ten tracks in the unit memory. The Track Log starts recording as soon as the unit gets a satellite location fix and the Track Log feature is turned on. When you no longer need a Track Log you can press the on-screen 'Clear' button to remove it. If you want to keep a record of a certain track log or use the 'TracBack' feature, clear the Track Log before you start traveling. The percentage of memory used by the current track log displays at the top of the page. After the Track Log is 'Cleared', it displays zero percent. When the last track point (bread crumb) is dropped, the most recent track points start to overwrite the least recent if the default setting 'Wrap When Full' remains selected on the track log setup. If it is not selected, after the last bread crumb is dropped, the Track Log stops. To avoid losing track points, save the Track Log when it approaches the 99% mark. The Saved Track Page displays the track and it also can be displayed on the Main Map Page as you navigate. The 'TracBack' feature allows you to retrace your track in both directions. Tracks are marked BEGIN and END. The Recording Method allows you to control how often the track points (bread crumb) are dropped. It is based on Distance (from 0 to 9.99 miles), Time (up to 99 hours, 59 minutes, and 59 seconds), or Automatic (More Often, Normal, Less Often, or Least Often). Use the Options Menu to delete all saved tracks. Tracks Tracks Page Track on Main Map Page For effective use of the "TracBack" feature, clear the Track Log before starting a new trip or after saving the Track Log. Rename saved Track Logs to help indentify them later. 39
