Humminbird and Lowrance both do a good job, but I have to admit I like my Lowrance HDS units better than my Humminbird 798's. The Humminbird units are very simple with only a head unit and one transducer, but the tradeoff is that their DI isn't really DI. That may be why Tap Out doesn't use his much. Hbird uses their regular 2D transducer and the 2D image to produce an image "interpretation" using software to do it. On the Lowrance, they actually have two transducers, one for 2D and another for SI and DI. They also have a Structure Scan unit (seperate from the head unit) to produce real SI and DI. That makes a big difference in the quality of the images. I have Hbird 798's on my other boat and liked them fine (and still do), I just think the Lowrance does a better job.
