I will never buy another Lowrance/Eagle product. The screen on my Eagle 640C went bad. I thought no problem. I can replace it. Lowrance said they do not support parts or service on any product over 3 years old! After 3 years you can not even buy replacement parts! That is crazy! What kind of company pulls all the spare parts inventory after 3 years and forces you to buy new? Certainly not a very reputable one!
