Is my transducer fried?

got a eagle fishelite 480–worked great at high and low speeds until a few months ago–now it freezes up and shows the last know depth for a while then starts working again for a while–really no pattern to it messing up–nothing has been moved -checked angle and its still the same-cleaned the transducer off well-while flashing depth i get vertical lines on the screen but it will show a change in the bottom between the lines-- very frustrating with the money i put into this thing plus the map card i bought for it–any body have any suggestions --any kind of test or reboot i can can try on it?

I’d be in touch with Eagle. One possible point of failure would be the transducer cable connection into that back of the unit. Is it immaculately clean and are the pins/sockets nice and snug? Or, are there any signs of damage to the transducer cable itself? After that, I’d call Eagle.

eagle says since its a discontinued model they really cant (or dont want to) do much for me :frowning: -they just want to sell me a newer model-this one is only 4 yrs old-cleaned pins well and applied small amount of dilectric grease but no change --transducer cable does have a rub on it where the battery pinched it against the transom one choppy day on lake-but integrity of cable sheathing is still good --can a cable be cut and spliced --i’m pretty handy with a soldering iron

It sounds more like a software problem than transducer. I’m with Mr. Scott, call Eagle.

Oops, I see you called Eagle [:I]Buy a Humminbird?

And yes you can splice the cable if you are good with that sort of thing.

If the screen is completely freezing and not moving then it’s not the transducer. If the screen keeps rolling but it’s not reading the depth right then it might be the transducer.

screen keeps moving–just shows heavy vertical lines–like a noise interferance but have turned off all other electronics and it still does it–asked the folks at eagle if i bought a new transducer and it didnt fix the problem can i send it back for a refund and they said “no”–thats the problem–dont want to throw money at this unit if i might have to buy another–their reply to this was “send it and 150 bucks and we will see what we can do”–a new transducer costs 70 brand new–so i will be better off just buying that- was hopeing somebody on here would know the resistance values thru this transducer so i could test it myself–you would think as high priced as the newer graphs are they would have some sort of self-check program built in

wish i still had my x-16 paper graph–never a hiccup–paper just got to be hard to find–they dont make em to last anymore–if it werent for being spoiled with the gps and bottom contour map i would go back to a flasher !

Poboy I am having the same kind of problem with my garmin 441s unit. When I run through choppy water the unit looses the bottom reading and then just locks up. I have to shut the unit off and sometimes even turn the battery switch to off as a sort of re-boot procedure. This is very agravating but I’m not sure wether to go transducer or power source or what??? Sorry I’m not offering any solutions, but I know what your dealing with. Sometimes after the unit locks up I say “stick the depth finder in the water to see how deep we are” and piont to the boat hook laying on deck.

i found a thread in another forum that suggested a “soft reboot” -turn the unit off and hold down the pages key–tried it on land and it did look like something reset–im gonna try it out tmrw–but just in case i wired up my x125 and mounted to the other side --im pretty sure i cant use them at the same time but i can switch between for now–i did notice the ping felt stronger after the reboot

Poboy, I had a Lowrance x91 that did the same thing. I found a transducer for $18 online from some marina in Florida and it worked fine.
