Bottom Range (Sonar Zoom View Only, When Bottom Lock Is On) - Humminbird HELIX 5 SI GPS Operation Manual

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.
