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 in the depth window 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.

TIME—the time of day, displayed using your selected time format.
TIMER—an alarm that counts down or up in the increments that
you set in the Alarms System sub tab.
TURN—the degrees that you must turn left or right to make your
direction of travel match your bearing. Steer left (L) or right (R)
until this reads 0 to go directly to your destination.
VMG (velocity made good)—the rate of closure to a destination
based on your current speed and course.
VOLT—the current battery voltage input.
WTR TEMP (water temperature)—the water temperature at the
transducer.
XTE (crosstrack error)—how far off the chosen course you are,
measured by your selected distance units. This indicates if you are
to the left or right of the course.
