The results derived from the DownScan Imaging are so clear they appear nearly photographic, so that you can quickly and easily identify everything it picks up. You can see both hard and soft bottoms, beds of seaweed, eager fish and more. Even thermoclines are clear, so you can see the difference in the water temperatures.
