Set Offset (waterline or keel)
The Set Offset function adjusts the digital depth readout to display depth
readings from the waterline or the keel (lowest point of the boat) instead of the
transducer location.
1. Choose to measure the depth from the keel or waterline.
Keel: Measure the vertical distance between the face of the transducer
and the keel of the boat.
Waterline: Measure the vertical distance between the face of the
transducer and the waterline of the boat.
2. Press the MENU key until Set Offset is displayed and flashing on the screen.
3. Enter your chosen offset measurement as follows:
Keel: Press the DOWN arrow key to enter the
measurement from step 1 as a negative (-)
number. (-1 to -10 feet, -.1 to -3.0 meters, or
-.1 to -1.6 fathoms; Default = 0)
Waterline: Press the UP arrow key to enter the
measurement from step 1 as a positive (+)
number. (+1 to +10 feet, +.1 to +3.0 meters, or
+.1 to +1.6 fathoms; Default = 0)
4. After your selection is made, wait 5 seconds for the unit to return to normal
operation. Your settings are saved automatically, and the offset icon will be
visible on the display.
