Before setting keel offset, measure the distance from the transducer to the lowest 
part of the keel. If, for example, the keel is 3.5 feet below the transducer, it will be 
input as –3.5 feet.
To set Keel Offset:
1.   Highlight  the  Keel Offset text box on the Installation menu and press 
enTeR
2.   Use the keypad to enter the desired keel offset. Select OK and press 
enTeR.
Water Speed Calibration
When there are differences in speed data,  Water Speed 
Calibration calibrates data from a paddlewheel with GPS 
data. That ensures the accuracy of speed data from your 
paddlewheel. 
To calibrate Water Speed:
1.   Select  the  Water Speed Calibration  text  box  from  the  Installation 
menu and press 
enTeR. The Water Speed Calibration keypad will 
appear. 
2.   Use the arrow keys to enter the percentage difference in speed 
data. Select OK and press 
enTeR.
NOTE: To input a keel offset that accounts for the distance 
from the transducer to the water surface, you will enter a posi-
tive number. If the transducer is 1.5 feet below the waterline, 
it will be input as +1.5 feet. That will give you a more precise 
depth reading.

NOTE:  If the paddlewheel is reading a slower speed than the 
GPS unit, you will input a positive (+) percentage. Conversely, 
a negative (–) percentage will be entered if the paddlewheel is 
reading a faster speed than the GPS unit.
