Never was impressed with hummingbird, I like my Lowrance have 7 inch HDS touch on console to locate structure and fish have Hook 7 on bow use it mainly to follow contour lines and get depth also when trolling for eyes I mark the fish on bow unit before they strike. When I fish with my buddy in his boat I really miss the structure scan the touch unit is a lot more user friendly than the non touch units. Just personal preference and what you are used to.
