Upper Range (Advanced: 2D Sonar, 2D Big Digits Views Only) - Humminbird 531338-1_C Operation Manual

Upper Range sets the shallowest depth range that will be displayed. The Upper Range menu
choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and
is only available on the X-Press™ Menu when you are in the 2D Sonar or 2D Big Digits Views.
Upper Range is often used with Lower Range.
For example, if you are only interested in the area between 20 and 50 feet deep, you
should set the Upper Depth Range to 20 and the Lower Depth Range to 50. The 2D
Sonar View will then show the 30 foot area between 20 and 50, and will not show the
surface or the bottom (assuming the bottom is deeper than 50 feet), and will show
greater detail for that area between 20 and 50 feet.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range
regardless of the manual settings entered.
To adjust the Upper Range:
1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar X-
Press™ Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Upper
Range setting. (0 to 990 feet or 0 to 327 meters [International Models Only], Default
= 0)
