The Downvision image is shown here as the copper tone (standard palette) and typically shows the structure of the seabed in great detail, individual fish show up as round dots, plant life can be clearly seen, as can features on the seabed such as reefs, even mooring chains and wrecks, whereas the conical sonar shows the more traditional view with individual fish showing as arches but structures are less distinct.

The view in these pictures below of a submarine on the seabed indicate the greater level of detail available from the downvision capability

The FAQ click here also gives more examples of the differences between the technologies which require different types of transducer.
