I have a friend that is looking to buy an inexpensive used Garmin, Furuno, or Raymarine multifuntion unit. He has a Garmin depth finder with a transom mount transducer. He also has a very old Furuno GPS that is terrible. I found a Raymarine A60 on craigslist for around $200 by itself but havent heard back from the seller. Would like to find someone looking to get rid of an older set up if upgrading. Of course, he would like to get sounder and ducer too. If anyone knows of anything that could be picked up fairly cheap I would appreciate it.
