Red_King814 I think you and I are about in the same boat. After asking for a fish finder for Christmas, my wife had me pick one. Knowing our budget was limited, and still stretching it quite a bit I asked for a Hook 4 chirp. It has down imaging and sonar. Being that it is not Christmas yet, I am not allowed to open the box and it is killing me. What I have found out, however, is that apparently Lowrance remade the "Elite" units that had basic sonar, changed to Chirp sonar and are now selling them as "Hook" units. This being my first fish finder I have nothing to compare to, I chose the Hook 4, as it has a larger screen. It was advertised as Chirp 2d sonar, down view, and a sd card slot for plotting. However right or wrong, maybe WayneP will chime in and help out, but I will gladly pass on to you anything I find out, but it seems that there aren't even utube videos on the new (Hook) name, only the "elite" name. Had I known that before I had my wife buy it I may have chosen a different brand name, however I am excited over having a maps sd card capable unit for the lower price. I think that is why you have had no replies yet, as the new Hook name is so new that nobody has had the time to compare or had time on the water with these units.
