  • Trolling line depressor
    Patent number: 4951413
    Abstract: A troll line depressor includes a pair of triangular wings with a dihedral angle of about 100 degrees therebetween. A rigid bridle connected between the upper and lower ends of the depressor provides a sliding connection for a ring at the end of a towing line, so that the depressor normally develops hydrodynanmic forces to depress the end of the towing line, but can tilt backward to an inoperative position when a fish strikes, or forward to an inoperative position if the depressor engages river bottom debris.
