Abstract
An aid for temporary attachment of a fish line to facilitate casting a lightweight lure or bait some distance to a desired location. An elongate body member has an arm at one end for engagement with a fishing line. A disposable weight is carried by the casting aid to provide desired momentum to a cast line. A buoyant body on the aid is acted upon by water displacement and/or by submersion to rotate the arm of the aid out of line engagement for release of the aid. The buoyant body may be of rounded shape for aerodynamic purposes. The buoyant body may be formed having an airfoil shape to assure positive engagement of the aid with the lure or bait during the cast.
