<p>A self-propelled fishing float, with cylinders mounted therein that carry spring-biased pistons therein. A sinker, lead line and hook are received within each cylinder, with the piston depressed against its spring, the sinker being held in place by a lever mechanism connected to a timer. At a predetermined time after launch of the float the timer actuates the lever mechanism to release the sinkers, whereupon the spring-biased pistons discharge the sinkers with their attached hooks into the water.</p> |
