From a Traditional sonar view, select MENU > Sonar Setup > Advanced.

Shift

Allows you to set the depth range on which the sonar is focused. This allows you to zoom in a higher resolution in the focused depth.

When using shift, bottom tracking may not work effectively, because the sonar looks for data within the depth range of the focused area, which may not include the bottom. Using shift also can impact the scroll speed, because data outside the depth range of the focused area is not processed, which reduces the time required to receive and display the data. You can zoom in to the focused area, which enables you to evaluate target returns more closely at a higher resolution than just zooming alone.

Btm. Srch. Limit

Limits the search for the bottom to the depth selected when the Range setting is set to Auto. To minimize the length of time it takes to find the bottom, you can select a depth to limit the search for the bottom. The device will not search for the bottom deeper than the selected depth.

Range Sync > Off

The range for all sonar views in a combo screen are independent of one another.

Range Sync > On

This setting option is available only when viewing a combo screen using at least two traditional and Garmin ClearVü™ views in a combo screen. The range is synchronized for all traditional and Garmin ClearVü views in the combo screen.

Range Sync > Same Transducer Only

This is the default setting. The ranges are synchronized for views from each transducer in the combo screen, but not between different transducers.

NOTE: This setting does not apply to a dual-band CHIRP transducer.

Scroll Sync

This setting option is available only when viewing a combo screen using at least two traditional and Garmin ClearVüsonar views in a combo screen. The scroll rates are synchronized for all traditional and Garmin ClearVü views in the combo screen.
