I have a Lowrance LMS-520c GPS/Sonar unit and my sonar will work for a while and then it won't be picking up my depth. The depth numbers will be flashing. I also have a Minn Kota Powerdrive trolling motor with the co-pilot. I'm using the built-in transducer with my sonar unit. Has anyone else had these problems? I talked to a sales rep at BPS and he said some of the Minn Kota transducers had been replaced. Thanks
