Brush depths of anywhere from 3-16 ft. I have been back in the creeks and out to the mouths. Have covered alot of water. I don't have structure scan but I do have a lowrance unit that is about 5 years old. I have spent a little time learning how to find brush. Im still learning that part of it. Up to this point I have only been using jigs- maribou, bobby garland plastics, crappie tubes and road runners. Trying those in several colors.
