ABSTRACT:
An apparatus and method for sensing objects under water, such as fish or clams, is provided. First and second handles attached to a base are provided. A plurality of protrusions are attached to the base and protrude from the base. The first and second handles are part of first and second rigid members. The first and second rigid members are preferably elongated and each have a top and a bottom. The first and second handles lie at the top of the first and second rigid members. The base is preferably connected to the bottom of the first and second rigid members. The base preferably is more densely weighted than the first rigid member and more densely weighted than the second rigid member. The base, and first and second rigid members may have a plurality of openings which allow water to pass through. The first and second handles may have outer shapes comprised of first and second curves. The first curve may have substantially lesser curvature than the second curve to provide a handle and to provide an easy to maneuver and lightweight apparatus.
