Frequently Asked Questions
Navigation Screens
Why does my compass not point in the right direction?
The SporTrak computes direction by comparing your present
position to the last position taken, it requires that you be moving
to compute your compass heading. Furthermore, to eliminate
error, you must be moving at a minimum of 0.5 mph.
Routes
What is a backtrack route?
A backtrack route allows you to “retrace” your steps. As you are
moving, the SporTrak automatically creates and stores hidden
waypoints into memory. These waypoints are the ones that the
SporTrak will use to retrace your steps. When you create a
backtrack route, the SporTrak converts these hidden waypoints
into User Waypoints.
How do I know which route is active?
Access the route menu by pressing the MENU button and select
the option Routes. The route menu lists all of the routes in
memory with the active route displayed in bold characters.
Alarms
Why does my SporTrak not make an audible beep when I have an alarm
active?
Check your setup settings for the Beeper. If the selection is Off
or Keys Only, the beeper will not sound for alarms.
Output Data
What is NMEA?
NMEA (National Marine Electronics Association) is the
standard used for interfacing marine electronic devices. This
standard has also been adapted for use in a variety of third-party
mapping software programs.
