When you pause the sonar display, the system continues to gather sonar information in the background. When you resume sonar scrolling, the sonar data gathered while scrolling was paused is refreshed on the sonar display with a line indicating the point where you paused it.

In most cases, all of the sonar data gathered while it was paused is shown on the screen immediately after you resume scrolling. The location on the graph where you paused scrolling is indicated by a dashed line.

Factors such as the number of sonar windows being viewed, the speed and range of the sonar transmissions, and the capabilities of your chartplotter may reduce the amount of sonar data saved, depending on how long the scrolling was paused. When scrolling is paused longer than the device is able to retain the data, the last recorded point is indicated by a solid line on the graph.
