sonarfishfinderoverlays
Sonarfishfinderoverlays refer to digital information layers that are displayed on top of the sonar screen of a fish finder to provide additional context for interpreting underwater environments. These overlays combine sonar data, such as depth, bottom structure, and fish arches, with external information like maps, bathymetric charts, waypoints, markers, and annotations. They may be created by the fish finder itself or loaded from external sources and are designed to help users understand spatial relationships and target areas more efficiently.
Common implementations include map overlays that show contour lines, shoreline features, and landmarks; structure overlays that
Advantages of using overlays include enhanced situational awareness, faster identification of productive areas, and improved navigation
