I know that with the thread about lowrance customer service that I will have some negative comments, but I'm really torn between the 597HB ci di hd combo and the Lowrance elite 5 dsi. Friday is the day that I'm going to buy something and I just can't make a decision. I currently have lowrance x47's on my boat now. They were on the boat when I purchased it and I've never owned anything else. Can anybody shed some light on this subject that might own one of these units. Thanks in advance.
