Like I said Greg it made a Lowrance guy out of me for 30+ years. Back in the 80's the Humminbird CS guy told me to send in my CH-30 and it + so many hundred dollars they would send me a new LCD unit.
Looked in my bass pro catalog and I could have got it cheaper just flat out buying it from them without sending anything in. I was glad when Johnson took over the old Humminbird. Because if it was the same old company I still would not own a Humminbird.
before retiring I worked with a Company who had a lot of bean counters who had to justify their jobs everyday.
They came up with terms like , going forward costs , stranded investments etc etc. CS was always under some kind of search and destroy on its funding because customer satisfaction is a non-tangible asset.
Lowrance also chased me away when they changed hands. Their CS went south in a NY second. So after extensive research I finally returned to try Humminbird again.
By the way that CH-30 was the best FF I ever owned. When it said fish were there they were there no ifs ands or buts. I love my new 1198C but have extremely short history with it. the 987C and 997 C were good units also.
