Just finished replacing my depth sounder/fishfinder, I installed a Garmin 340c. I had an old Eagle unit that worked great when it wanted to, I got tired of the flashing number not registering the correct depth. It was tired and seemed to be getting worse, upon examination of the old one the wire at the transducer was cracking and exposed. I hope this new one works better. Anyone do an upgrade like this and get better results?
