I was going to try and stay out of discussions like this but I keep grinding my teeth. Understanding the side scan is easy. Just as a very basic, you see a blob over there, there's some thing over there to check out. Soon you get to where, oh this is deeper water by the size of the water column. Then it's, oh look at that boat on the bottom. The hardest part about using these is deciding whether or not to go back and check out what you just saw about 20 dozen times a trip.
