I've purchased an Eagle 320 fishfinder 2 years ago and I've had to replace my transducer twice. Every time I'm out fishing lakers in 50 to 100 feet of water, I keep loosing the bottom mark and the graph simply goes blank with the 0 depth mark flashing in and out on the screen. When this happens I hear a clicking sound coming from the transducer in the water. When I informed by dealer LeBaron where I bought the unit, I was suggested to replace the transducer as it the clicking sound meant the transducer was no longer any good. I've bought a new last year and I kept it indoors all winter and the same problem occured this spring. How can this be when my previous fishfinder was a Lowrence and the transducer lasted me for 10 years. Any help would be greatly appreciated as I leaning towards throwing out this fishfinder. Jean
