Humminbird 345c, 345C DI Bottom Range, (Sonar Zoom View only when Bottom Lock is On)

Bottom Range(Sonar Zoom View only when Bottom Lock is On)

Settings: 10 - 60 feet, 2-10 fathoms, or 3-20 meters [International Models only], Default = 15 feet

Bottom Range allows you to control how much of the water column, measured up from the bottom, is shown in the Sonar Zoom View. Choose a small value to see low-lying bottom structure or details of the bottom return. Choose a larger value to see large structure in deeper water.

NOTE: It is possible to set the Bottom Range to be greater than the depth. In this case, you may see surface clutter in a wavy band that mirrors changes in the depth.
