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

setting to on. (Off, On, Default = Off).

be displayed. (10 - 60 feet, 2-10 fathoms, or 3-20 meters [International
