DESCRIZIONE
An integrated fish detection module/navigation module system that may provide the location of fish over a distance or time is provided herein. The location of fish can be presented on a navigation module display to provide information regarding the location of fish relative to navigational data known to the navigation module. The information may create a record of fish location over time and distance. In some configurations, the navigational data and fish detection module data of more than one watercraft may be combined and distributed. In some configurations, a marker may be automatically placed on a navigation module to indicate that fish have been detected at the location on the navigation module. [Image Omitted]
