Not sure if this is an option for you, but I have a Garmin Echo 551DV that came with my boat. I cut the transducer cable with my trolling motor bracket and decided to update to one with maps. If you wanted to buy a new transducer (which is around a $100) or try to repair the cut one, I would give it to you. I live in Rochester.
Retired last yr got more time on my hands to fish so going to replace my ancient Eagle Fish I.D. II, bought it new about 20 yrs ago.There are so many to choose from its mind boggling, been up all night/mourning researching the Garmin Striker series. Any1 have a Garmin Striker Plus 4 or Garmin Striker Plus 4cv. I kind of narrowed it down to those 2 cause bigger screens and quickdraw contour mapping. I liked the standard Garmin Striker 4 since it has a flasher but then I would have to spend more to get the icefishing transducer plus its a smaller screen.The garmin brand got my attention cause of the GPS mapping part, not really research any other brands there's just to many. Would like to have side view but to pricey.
