Abstract: A sonar system mounted to a platform is disclosed. The sonar system includes a positioning shaft rotatably connected to the platform; a motor operably connected to the positioning shaft, wherein operation of the motor causes the positioning shaft to rotate; a transducer connected to a distal end of the positioning shaft such that rotation of the positioning shaft causes the transducer to rotate, the transducer defining an axis aligned with a sonar field projected by the transducer; and a position indicator connected to and extending from the positioning shaft to a position viewable by a user, the position indicator being aligned with the axis of the transducer to provide a visual indication to the user of a direction of the sonar field projected by the transducer.
