KEEL OFFSET

The Keel Offset function adjusts the digital depth readout to display depth readings from either

the waterline or the keel (lowest point of the boat), instead of from the location of the transducer

(which is usually somewhere in between). This function lets you display transducer location and

depth readouts suited to your needs.

1. To determine the value to enter into the Keel Offset setting, first decide whether depth

from the waterline or depth from the keel is desired. Measurements will need to be made

for the location desired.

2a. For depth from the keel of the boat, accurately measure the vertical distance between the

face of the transducer and the keel of the boat. You will then need to enter this

measurement into the Keel Offset function as a negative (-) number.

2b. For depth measurements from the waterline, accurately measure the vertical distance

between the face of the transducer and the waterline of the boat. You will then need to

enter this measurement into the Keel Offset function as a positive (+) number.

3. After your selection is made, wait 5 seconds for the unit to return to normal operation. The

Deep icon should now be visible.

4. If the depth of the water is greater than the selected value, the alarm will sound and the

Deep icon will blink to indicate the alarm state. Pressing any key will mute the alarm;

pressing the SET key will mute the alarm and activate the Deep Alarm function for

additional adjustment. To permanently turn the alarm off, use the DOWN Arrow key to

return the display to Off.

UNITS

The Units control function selects the units of measure for depth readout and alarm functions. The

three settings available are: Feet, Meters or Fathoms.

1. While in normal operation mode, press the SET key until Units is displayed and the Units

icon is blinking.

2. Use either Arrow key to view the unit choices until you reach the desired unit: FT for feet,

M for meters, FA for fathoms.
