number to display water depth. Enter a 0 in this value to
display depth below keel and depth below transducer.
2
Select Settings > My Vessel > Keel Offset.
3
Select or based on the location of the transducer.
4
Enter the distance measured in step 1.
Setting the Water Temperature Offset
You can set the temperature offset to compensate for the
temperature reading from a temperature-capable sensor.
1
Measure the water temperature using the temperature-
capable transducer that is connected to the device.
2
Measure the water temperature using a different
thermometer or temperature sensor 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 device
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 device measures the water
temperature as being warmer than it actually is.
4
Select Settings > My Vessel > Temp. Offset.
5
Use the arrow keys to enter water temperature offset
measured in step 3.
