Transducer problem?

Recommended Posts

Hey folks!

I am asking this question on behalf of my brother. He has a fishfinder' that has GPS, temp and speed. I think it's a lowrance. Recently, it is not marking bottom, but all other functions work as they are supposed to. The transducer was checked for proper location, tilt and connections, all looks right.

The unit is fairly old. Would it be a reasonable idea to simply change out the transducer? Is this the likely culprit? Ideally, he does not want to buy an entirely new unit.

Any advice appreciated!

Older units do burn out transducers

the best thing is to try his unit on another ducer

older units you should be able to feel the pulse  on the bottom of the ducer  when running

Transducers absolutely have a shelf life and need replacing. If the transducer is older than say, 6-8 years, depending on the use it's seen it may need replaced. If possible, try another transducer manually to see if it works.

He,s retired thats why.

Is it possible he might of left the finder on while out of the water? I did that once and burnt out the transducer. Over heated I was told.

Transducer do need to be replaced. you can test the unit with another transducer or often you can turn on your unit with the transducer out of the water and you should be able to hear if it is working!

I can hear mine clicking away on my pontoon, even a foot down in the water. :rofl2:

This is a fact. It may not be necessary but if I'm largie fishing up shallow(<4') and tight to the boat(flipping docks, wood, etc.), I'll put my graphs on standby. That turns off two transducers from clicking away.

I just replaced a transducer on my fish finder. It wouldn't mark the temp and it showed all kinds of wacky depths. It clicked away when it wasn't working, so you can't depend on that as a sign that the transducer is shot. The new transducer fixed everything.

Update... he can hear the transducer pinging in the driveway. The main unit seems to be running rather warm, it's warm to the touch.

He did contact the folks in Woodstock, Angling Specialties and it looks like a new unit is in order.

Thanks to all who chimed in.

    • Motor guide problem

      I have a Motorguide Pro series 46 bow mount TM that has worked trouble free until today. I had been using it for about an hour when it acted up - it stopped running for a few seconds, then started again with a bit of a jerk, then ran for a few minutes, stopped, started a few times then just stopped for good. When I got back I checked what I could, battery is fine, all connections I can see seem fine, it just won’t run. Any suggestion on a next step? Does anyone know a repair
