I got this Garmin at Christmas this year ( https://www.tndeer.com/threads/depth-finder-school-me.446542/ ) and this just is over my head, too many options etc. for an old guy like me, I don't do good with buttons and should have known better. The unit is as new with all documents, hardware except the 2 stainless screws used to mount the transducer bracket. $400.00.
