Bank side and aquatic cover can impair the fish’s vision; consequently, use bank side brush to conceal you during your approach, and to hide your position. Although light refraction can sometimes allow fish to see around corners, fish can see you when you cannot see them. By taking the fishes’ vision window into account, mask your approach by placing cover between you and the fish. But watch out for the light refraction phenomenon that permits fish to see around corners.
