Calibrating the Sensors–Screen #4
While not necessary, you have the ability
to calibrate speed if desired. Remember that
due to differences in transducer mounting,
no two boats will read speed exactly the
same. Calibration is best done when water
conditions are calm. Lower the Probe 5-feet
under the transducer and compare the
surface speed to the Probe speed. Press
the SET button until the speed reading ashes for
the sensor you want to adjust. Once that speed reading
ashes, press the UP or DOWN arrow to adjust. Once
you’ve adjusted the speed readings to match each other,
press the POWER button once to save your changes.
Factory setting values are denoted for each sensor by a missing decimal point.
If you wish to go back to the factory settings press the UP or DOWN arrow until
the reading ashes without a decimal point. The factory default value is always in
the middle of the adjustment range. When the reading ashes without a decimal
point, press the POWER button once and the factory default will be restored.
The reading will
flash when selected.

Setting the Speed Unit of Measure–Screen #3
This screen allows you to select the unit of measure for speed.
The surface and probe speeds will automatically be in the same
unit of measure. The Fish Hawk will display speeds from .4 MPH
to 11 MPH at the probe and from .4MPH to planning speeds at
the surface.

Setting the Temperature Unit of Measure–Screen #2
This screen allows you to select which temperature unit
of measure is displayed on the screen. The Fish Hawk will
display temperatures ranging from 32 degrees to 104 degrees
Fahrenheit.
Press UP or DOWN arrow to
toggle between °F and °C.
Setting the Gain–Screen #1
The gain is also referred to as sensitivity, and ranges
from 0 to 25. The factory default setting of 15 usually
provides excellent results. The gain control only has an
effect on the probe function. Most of the time no or
only small adjustments are necessary. Increasing the
gain allows probe readings to be received from greater
depths. Lower gain settings reduce the possibility of
other sonar or electrical interference, and also may be
necessary in shallow water
