Zoom provides a magnified view of the bottom and structure.

When ZOOM is set to Auto, the upper and lower Depth Ranges are automatically adjusted to keep the area above and below the bottom on the display. Select Off to return to normal operation.

Manual: There is also a series of manual ranges which can be selected. The manual depth ranges are determined by the present depth conditions.

Chart Speed determines the speed at which the sonar information moves across the display, and consequently the amount of detail shown.

A faster speed shows more information and is preferred by most anglers; however, the sonar information moves across the display quickly. A slower speed keeps the information on the display longer, but the bottom and fish details become compressed and may be difficult to interpret.
