Re: Fish/Depth Finders
From talking to the factory technicians, they say that the transducers on all depthfinders wear out over time. Most recommend replacing them every 5 years.<br /><br />The transcucers vibrate at their rated frequency, and you can feel it if you place your hand on the bottom of one that is turned on out of the water.<br /><br />Incidentally, they (the technicians) say it is really rough on the transducers if you leave them on for any extended period out of the water. The reason is, the unit will go to maximum gain, and hammer the heck out of the transducer.<br /><br />The way you know your transducer is going bad is when it will show the bottom so so, but will not show any fish at maximum gain.
