Patent ID: 7174668

Claim:
A marine animal control device comprising: a hollow, tubular, watertight, buoyant rod having a proximal handle end and a closed distal end; first and second electrical prongs extending from the interior to the exterior of said rod through said closed distal end; a retractable, hollow, tubular sheath slidably mounted to said distal end of said rod; said sheath having a first non-retracted position wherein said first and second prongs are within said hollow tubular sheath; said sheath having a second retracted position wherein said first and second prongs are at least partially exterior to said hollow tubular sheath; wherein said retractable sheath is spring loaded to maintain said sheath in said first position when said sheath is not acted upon by an outside force, and to return said sheath to said first position from said second position upon release of said outside force; and wherein said spring loading is provided by a spring connected between said sheath and said distal end of said rod, said spring being selected from the group consisting of a compression coil spring, an extension coil spring, a clock spring, a torsion spring and a leaf spring; a power supply having a positive terminal electrically connected to said first prong and a negative terminal electrically connected to said second prong; a voltage multiplier circuit connected between said power supply and said first and second prongs; a first power switch electrically connected between said power supply and said voltage multiplier circuit to connect or isolate said power supply from an input side of said voltage multiplier circuit; and a second power switch electrically connected between said first prong or said second prong and an output side of said voltage multiplier circuit to connect or isolate said output side of said voltage multiplier circuit from said first prong or said second prong.
