Using the Fishfinder 340C > Configuring Advanced Data Fields

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).

To toggle the data field appearance:

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:

1.Press and hold the DATA/CNFG key to access the Advanced Data Menu. The current configuration appears on the left side of the screen. The available data field options appear on the right side.

2.Use the ROCKER to select the Wide or Narrow tab.

3.Press down on the ROCKER to select the slider. Then 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 change.

5.When you are finished, press QUIT to exit the Advanced

Data Menu. Your new choices appear on the screen.

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.
