Is movement required for side imaging to work?

Does the boat have to be moving for the Side Imaging Sonar to work?

Yes. Side Imaging Sonar works much like a MRI. The beams are laser thin and as they move past an object they take 100’s of thin slices of the object and compile them into a high-detailed image of the object. If the boat is sitting still the beams will continue to take thin slices of the same spot and continue to show the slice of this spot continuously.
