Garmin GPSMAP 195 - Manual (Page 84)

REFERENCE
The TracBack function
will create a series of tem-
porary waypoints along
your track log back to the
oldest track log point in
memory.
The general purpose
timer field offers a count up
and count down timer. You
may also select from a vari-
ety of other timers to keep
track of trip times, battery
life or elapsed time using
the other timer options.

TRACBACK NAVIGATION (cont.)
• If there is not enough available memory to add more waypoints
and create a TracBack route, you will be alerted with a ‘waypoint
memory full’ message, and the receiver will use available
waypoints to create a route with an emphasis on the track log
closest to the destination.
• If the track log interval is set to the ‘Time’ option, the route may
not follow 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, the TracBack will draw a straight line between any point
where coverage was lost and where it resumed.
• If the changes in direction and distance in your track log are very
complex, 30 waypoints may not accurately mark your exact path.
The receiver will then assign the 30 waypoints to the most
significant points of your track, and simplify segments with fewer
changes in direction.
The timers submenu provides count down, count up, battery and
trip timers for the various time management needs you may
encounter in flight. The first timer function will count down from an
entered interval and alert you with a message or keep a running timer
that will count up to 99:59:59 while the unit is powered on.
