I've had a 1650 DF with a 50-200K transducer for 15 years. The unit recently fried out (rust) and I found a replacement on ebay as I did no want to replace the transducer and antenna. The newly installed unit works perfectly in GPS and Plotter modes but the depth finder is a problem. The reading I'm getting looks like it's in a default mode - always reading about 5' depth.
The leak that caused the rust came through the viewer (enclosure tore in a storm). The rest of the unit is protected and always dry. All the connections in the rear are clean.
The transducer has never been a problem. How can I determine if the problem is in the refurbished unit or the transducer?
