Track Log Submenu
The GPSMAP 135 Sounder’s main menu page’s track submenu lets you speci-
fy whether or not to record a track plot (an electronic recording of your path) and
define how it is recorded. It also provides an indicator of the track memory used
and selects functions to clear the track memory and start a TracBack route. The fol-
lowing functions are available:
• Record Mode— lets you select one of three track recording options:
• Off– No track log will be recorded. Note that selecting the ‘Off’ setting will prevent
you from using the TracBack feature.
• Fill– a track log will be recorded until the track memory is full.
• Wrap– A track log will be continuously recorded, wrapping through the available
memory (replacing the oldest track data with new data).
• Interval— defines the frequency with which the track plot is recorded. Three inter-
val settings are available:
• Time– records track plot based on a user-defined time interval.
• Resolution– records track plot based upon a user-defined variance from your course
over ground. The resolution option is the default setting and is recommended for
the most efficient use of memory and TracBack performance. The distance value
(entered in the interval field) is the maximum error allowed from the true course
before recording a track point.
• Distance– records track based on a user-defined distance between points.
• Interval Value— defines the distance or time used to record the track log.
• Delete Track?— allows you to clear the track log currently stored in memory.
• Start TracBack?— converts the current track log into an inverted route and begins
route navigation along the track log.
