Chart | Select the Map Source and Water Level Offset
Humminbird is the built-in map source for your control head. You can also select Navionics or C-MAP by Jeppesen as your map source. If
you install an SD card with additional maps, set the map source to match the SD card type.
From this menu, you can also set the Water Level Offset (Humminbird charts only). Water Level Offset allows you to change the level of
the water being read from the control head. For example, if the lake is down 5 feet, set the Water Level Offset setting to -5. The displayed
numbers on the Contour Lines will adjust from the Water Level Offset setting. See your control head operations manual for more
information.
NOTE: If you trailer the boat to a new location, the Water Level Offset must be reset according to the current environment.
