SONAR BEAM INDICATOR FOR A SONAR IMAGE

A system for presenting sonar beam indicators on charts for noting the direction of the sonar beam is provided herein. The system includes one or more transducer elements and a bearing sensor configured to measure a bearing associated with the one or more transducer elements during receipt of the sonar returns. A marine electronics device is configured to receive sonar return data from the one or more transducer elements and generate sonar images based thereon. The marine electronics device further is configured to determine a watercraft location, receive a measured bearing, plot a watercraft indicator on a navigation chart, and cause a sonar beam indicator to be displayed in association with the watercraft indicator based on the measured bearing. The sonar beam indicator displays an indication of the direction in which the one or more transducer elements are facing when the sonar return data was received.
