Clicking sound...
I'm a little confused - is the sound coming from the transducer or the display? Has it always done this, or is this something new? How loud is it? A technician once had me confirm that my depthsounder was working by listening for the click. Sure enough, it was there if I listened close to the transducer. Certainly was not audible more than a couple of feet away.A couple of suggestions (and that's all they are): you could have a damaged piezo element in your transducer that is loose and "hitting" something when the transmitter pulse comes along. Or, if the click is coming from the instrument, it could be a transformer in the transmitter circuitry in which the core is somehow being "rattled" at the pulse frequency.Derek
