16.14What is zoom range and zoom range shift?

These are available only on a zoomed Sounder screen.

The zoom range is the vertical extent of water that is shown in detail on the left hand side of the split screen; for example, just 5 m of the water column rather than the complete water column.

Use the zoom range shift to move the zoom range up into shallower water or down into deeper water, so that you can show any section of the water column in detail.
