Here is a series of 3 consecutive pictures, all taken within about 4 boat lengths. Note the depth,rough texture on the right side and the smooth bottom texture in the left. In the next shot, I am turning the boat across the rough texture. With Side imaging, you and get a good iead how a piece of structure lays, and follow it alot better.
"On the right side image how would I tell if this was a soft bottom or a hard bottom. Without actually dropping a line down to feel the bottom" --Tom, 05/06/08
"Hard or soft bottom returns in SI are usually lighter and darker colorations on the screen. This can also occur with changing depths, like this image. The SI beam shooting right, is reading on a upward sloping bottom, whilethe left beam is sloping deeper." --Rollie, 10/01/15
