Adjusting the Range of the Depth Scale

You can adjust the range of the depth scale that appears on the right side of the screen. Automatic ranging keeps the bottom within the lower third of the sonar screen, and can be useful for tracking the bottom where there are slow or moderate terrain changes.

When the depth changes dramatically, like a drop off or cliff, manually adjusting the range allows a view of a specified depth range. The bottom is shown on the screen as long as the bottom is anywhere within the manual range established.

  1. From a sonar screen, select Menu button > Range.
  2. Select an option:
    • To allow the device to adjust the range automatically based on the depth, select Auto.

    • To increase the range manually, select Down arrow button or Right arrow button.

    • To decrease the range manually, select Up arrow button or Left arrow button.

    NOTE: From a sonar screen, select Plus button and Minus button to quickly manually adjust the range.

    Setting the range on one screen applies that setting to all screens, except the SideVü screen.
