ABSTRACT:
A weighing device for attaching to the handle of a fish landing net or gaff has a tubular inner housing telescopingly received within a tubular outer housing, with a spring received between an annular collar centrally located on the inner housing and an internal shoulder on the outer housing. An "O" ring located on the side of the collar opposite the shoulder acts as a shock absorber and abuts a retaining ring that limits the travel of the collar in a direction away from the shoulder. A second shoulder spaced from the first shoulder acts to limit movement of the collar toward the first shoulder. A friction retaining adaptor attached at an end of the inner housing secures the net or gaff handle to the inner housing, and scale markings on the other end of the inner housing, which can be zeroed to eliminate the weight of the net or gaff, serve to indicate the weight of the fish.
