Not sure, but I lost bottom on my DFF3D the last time I went out. Actually, when i turned on the system in the water, the DFF3D never showed bottom.
I ended up fishing that day with just my traditional sonars.
I put in a request with a local marine electronics supplier / dealer to schedule testing my transducer with the airmar TDT1000 transducer tester.
What I am thinking happened is somehow my DFF3D was left on while the boat was on the trailer and I burned out my transducer. I make every effort to confirm all of my sonars and radar are set to standby mode when the boat is on the trailer and I am working on the boat, listening to xm radio, or messing with the chartplotter settings.
If the transducer tests out alright, I wonder what else it could be?
