TracBack NavigationThe third method of navigating to a destination isby using the GPS 125 Sounder’s TracBack feature. TheTracBack function allows you to quickly and easilyretrace your path using the track log automaticallystored in the receiver’s memory. The advantage of theTracBack feature is to eliminate the need to mark way-points along the way and manually create and activatea route back to where you began your trip.The TracBack route is created by reducing yourcurrent track log into a route of up to 30 waypoints,and activating an inverted route along those points.Once activated, a TracBack route will lead you back tothe oldest track log point stored in memory, so it’s usu-ally a good idea to clear the existing track log at thestarting point of your current trip (e.g. your car or thedock) before you get started.To clear the track log and define a starting pointfor a TracBack route:1. From the Menu Page, highlight ‘TRACK LOG’.2. Press F to access the track log page.3. Use the U key to highlight the ‘CLEAR LOG?’ option.4. Press F. A confirmation page will appear.5. Use L to highlight the ‘Yes?’ prompt and press F.To activate a TracBack route:1. From the Menu Page, highlight ‘TRACK LOG’ option.2. Press F to access the track log page.3. Highlight the ‘TRACBACK?’ option and press F.Once the TracBack function has been activated, theGPS 125 Sounder will take the track log currentlystored in memory and divide it into segments calledlegs. Up to 30 temporary waypoints (e.g., ‘T001’) willbe created to mark the most significant features of thetrack log in order to duplicate your exact path as close-ly as possible. A TracBack route from your presentposition to the oldest track log point will be created asan active route (the active route page will appear), andprovide steering guidance to each waypoint back to thestarting point of your track log.29Clearing the log before youget started will define theposition the TracBack func-tion will return you to.REFERENCETracBackNavigationHighlight ‘TRACBACK?’and press ENTER to beginTracBack navigation.
