Abstract:

A hydrodynamic fishing sinker attached to a fishing line and leader to which a lure is connected. The sinker comprises a plate member having upper and lower surfaces, a fin attached to the upper surface at one end thereof, and weights attached to the lower surface at the opposite end thereof. An arm is pivotally connected at one end to the plate member, the opposite end thereof being connected to a fishing line. The arm is movable towards the plate member when the latter assumes a diving attitude. A clip assembly is fixed to one of the plate member surfaces and lockingly engages a latch assembly carried by the arm, to hold the sinker in set position. The clip assembly is disengaged from the latch assembly under force exerted on the arm by a fish striking the lure or by a fisherman pulling on the fishing line.
