Lowrance electronic LMS-480M, LMS-480DF manual Depth Range Upper and Lower Limits

Depth Range - Upper and Lower Limits

Virtually any segment of the water column can be displayed by using the upper and lower limit feature. This lets you pick the shallow and deep depth range limits that are shown on the screen, provided there is at least 10 feet between the upper and lower limit you select. For ex- ample, a range from 12 feet to 34 feet could be used.

Changing the upper and lower limits gives you far greater control over the depth range. This feature lets you "zoom in" the display in almost unlimited combinations. Nearly any segment of the water column, from the surface to the bottom can be shown. This enlarges the sonar targets to best suit your fishing needs and water conditions.
