The brand new transducer Amazon sent to me has a problem with the temp sensor. I contacted Humminbird and after just a few moments they determined it was defective. After I notified Amazon of the problem they wanted me to send the transducer back to them and they would send me another one. For the average person that might be alright, but I fish almost everyday. I have been without my fish-finder for two weeks and I am not going to be without it any more. Since the problem is their fault I feel they should send me a replacement and I will send them back the defective one. Based on this experience I feel that Amazon is not customer oriented and does not trust anyone to do the right thing. I am very satified with Humminbird and their equipment but I will not use Amazon anymore and will do all I can to make sure everyone knows how I feel.
