The reason why this is one of the best fish finders with through Hull transducer is because it has basic display modes allow you to choose between single Low or High Frequency, A-scope, Bottom-Lock expansion, Dual, Bottom Zoom, Marker Zoom, as well as Nav Data display. You can choose from these operating modes or you can also choose manual mode. There is also an option for two auto modes where you can choose between fishing or cruising. The cruising mode is better than the fishing mode because, unlike the latter, the cruising mode utilizes clutter reflection setting which is higher than the other, making it useful to track the bottom even while you are cruising.
