I installed a new transducer last year. Installed it within manuf. specs. Worked great up to about 25 feet. After 25 feet it showed a bunch of noise. Marking at all levels. The markings happened at moving and at anchor. Below 25 feet seemed to work great even when up on plane. The depth part of it seemed to be working. I dropped anchor at 35 feet and measured rope and it was right on. It seems to show the bottom good and correct. Is the problem with the transducer, mount, or maybe the fishfinder itself? Any suggestions would be welcome. I know it should be used mostly to find structure and not to find fish but the noise is annoying.
