Bottom Range (Sonar Zoom View Only, When Bottom Lock Is On) - Humminbird 700 series 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, and is only
available in the Sonar X-Press™ menu when the Sonar Zoom View is active
and Bottom Lock is on. 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.
To adjust the Bottom Range:
1. In the Sonar Zoom View, highlight Bottom Lock on the Sonar
X-Press™ Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the
Bottom Lock setting to on.
3. Once you turn on Bottom Lock, the Bottom Range X-Press™ menu
choice will be displayed. (10 - 60 feet, 2-10 fathoms, or 3-20 meters
[International Models only], Default = 15 feet)
