Setting the Keel Offset
You can set the keel offset to display depth readings from the water line or from
the bottom of the keel, instead of the location of the transducer. If the transducer is
installed at the water line and you want the depth reading to reflect the depth of the
water from the water line, you do not need to set the keel offset. If the transducer
is installed at the bottom of the keel and you want the depth reading to reflect the
depth below the keel (keel clearance) you do not need to set the keel offset.

Select an option based on the location of the transducer and depth reading
type:
• If the transducer is installed at the water line
reading to reflect the depth below the keel (keel clearance), measure the
distance from the transducer location to the keel
value as a positive number.

Select ENTER.

Check the keel offset value to ensure you have entered the correct value.
Setting the Water Temperature Offset
NOTE: The device must be connected to a temperature-capable transducer to show
the water temperature.
The temperature offset compensates for the temperature reading from a
temperature-capable sensor.
1
Measure the water temperature using a temperature-capable transducer
connected to the fishfinder.
2
Measure the water temperature using a thermometer or a different 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.
