Re: lowrance Elite-5
A fish finders "pings" at 200 kHz. Unless your related to Superman, you can't hear the ping of a transducer.
The "click" you are hearing is either the static discharge in the piezoceramic crystal, a problem in the circuitry in the head unit or a problem with the inner workings of the transducer. From past experience with Lowrance transducers, ticking is never a good thing
