For depth from the keel of the boat, accurately
measure the vertical distance between the face of
the transducer and keel of the boat. This
measurement will then be entered into the Keel
Offset function as a negative (-) number. (Figure 9)
For depth measurements from the waterline,
accurately measure
between the face of the transducer and the
waterline of the boat. This measurement will
then be entered into the Keel Offset function as
a positive (+) number. (Figure 10)
To enable Keel Offset press SET until the KO icon
is displayed on the screen. The default setting of
the unit is off which is displayed as zero. From
the default setting of 0.0, use the DOWN arrow
to enter the negative (-) number to set the unit
for depth from the keel. Or, from the default
setting of 0.0, use the UP arrow to enter a
positive (+) number to set the unit for depth
from the waterline.
The available settings are +10 to -10 feet. After
your selection is made, the unit will return to
normal operation after 5 seconds. The "KO" icon
should now be visible as shown in figure 13.
Figures 11,12 and 13 depict a scenario where
the KEEL OFFSET has been set to -2 feet. Figure
13 shows the return to normal operation with
the updated depth readout.
