I appreciate the input on the subject. Stopped at Cabelas today and decided to buy a Lowrance Hook 9. I think it will take care of our needs. At $ 499.00, it seemed like a fairly good deal. Heck we bought the boat with a Garmin 230 on it. Probably a good unit in its day. I'm thinking its a little outdated at this point ( just like its current owner ). See You on the Lake. Nan Sea Lee
