The following selections require the proper NMEA data to view
information in a data field: Bearing, Compass, Course, Distance to
Next, Off Course, Pointer, Position, Speed, Time Of Day, Track,
Turn, and VMG. You must turn on NMEA Input/Output to receive
this data (see page 32 ).

Press and release the DATA/CNFG key to alternate
between the Basic and Advanced data field configurations.
To change or add an advanced data field:

press left or right to determine the quantity of fields of that
size.
4. Press down on the ROCKER to select a field that you
want to change. Press ENTER to see your choices. Press
ENTER again to select your choice. Your choice appears as
a new data field. Repeat this step for each field you want to

Data Field Definitions
BRG (bearing)—the compass direction from a location to a
destination, measured to the nearest degree. When using a GPS
receiver, bearing usually refers to the direction to a waypoint from
your current location.
COG (course over ground)—your direction of movement relative
to a ground location.
DCOG (desired course over ground)—the compass course between
the “from” and “to” waypoints.
DIST NEXT
(distance to next)—the length from your current
location to the next waypoint.
DPT (depth)—the depth of the water
NOTE:
If the Fishfinder is unable to track the bottom for any
reason, the digits which indicate depth flash on and off to alert
you that the Fishfinder is not tracking the bottom.
POINTER —an arrow that points toward a destination waypoint
from your current position (BRG). This field requires NMEA input.
SOG (speed over ground)—the actual speed that the GPS unit is
moving over the ground. This field requires NMEA input.
STW
(speed through water)—the speed as calculated by an
optional speed sensor on the transducer.
