Keel Offset.

Use the arrow keys to enter the keel offset measured in step
1.
Setting the Water Temperature Offset
Before you can set the water temperature offset, you must have
a NMEA 0183 water-temperature sensor or a temperature-
capable transducer to measure water temperature.
The temperature offset compensates for the temperature
reading from a temperature sensor.
1
Measure the water temperature using the temperature sensor
or temperature-capable transducer that is connected to the
chartplotter.
2
Measure the water temperature using a different temperature
sensor or a thermometer that is known to be accurate.
3
Subtract the water temperature measured in step 1 from the
water temperature measured in step 2.
This is the temperature offset. Enter this value in step 5 as a
positive number if the sensor connected to the chartplotter
measures the water temperature as being colder than it
actually is. Enter this value in step 5 as a negative number if
the sensor connected to the chartplotter measures the water
temperature as being warmer than it actually is.
4
Select Settings > My Vessel > Temp. Offset.
5
Enter the temperature offset calculated in step 3.
Calibrating a Water Speed Device
If you have a speed-sensing transducer connected to the
chartplotter, you can calibrate that speed-sensing device to
improve the accuracy of water-speed data displayed by the
chartplotter.
1
Select Settings > My Vessel > Calibrate Water Speed.
2
Follow the on-screen instructions.
If the boat is not moving fast enough or the speed sensor is
not registering a speed, a message appears.
3
Select OK, and safely increase the boat speed.
4
If the message appears again, stop the boat, and ensure the
speed-sensor wheel is not stuck.
5
If the wheel turns freely, check the cable connections.
6
If you continue to get the message, contact Garmin product
support.
Other Vessels Settings
When your compatible chartplotter is connected to an AIS
device or VHF radio, you can set up how other vessels are
displayed on the chartplotter.
