Down and Side Scan is mostly used for location of structure and for bottom detail.
It's can detect some fish..but that is not as good as the traditional transducer elements.

Fortunately most units use both structure scan and traditional in one transducer.
Most Side and Down scan units work best in less than 150'...and at speed less than 10 mph.
Very helpful fro location of structure...and reducing search time.
