Abstract: A fishing bobber is comprised of a hollow casing, a plug, a weight, a straw and a visibility marker. A weight is captively held moveably inside the hollow casing between one semi-closed end of the casing and a plug telescopically engaged with the other end of the casing. A straw extends through the center of the plug and communicates with the hollow of the casing and then extends to the distal end of the bobber where it is adorned with a visibility marker. A fishing line can be threaded from a fishing pole through the semi-closed end of the casing, through the hollow cavity in the casing, and out through the straw on the distal end of the bobber where a sinker and hook can be located on the fishing line. The hook is located a predetermined distance from the end of the line attached to the sinker.

Abstract: A fishing bobber that attaches to a fishing line immediately behind the weight when casting. The fishing bobber comprises an elongate tube having flotation means on one end and a water fillable cavity on the other end. A guide tube is adjustably fastened to the flotation end so that its distal end extends beyond the flotation means a predetermined distance. The water fillable cavity has inlet water perforations on its substantially closed end and a perforation in its tube sidewall for allowing a fishing line to pass therethrough to the fishing line tube guide. A magnetic ring is provided around the perforation on the substantially closed end of the cavity and a metal ball is moveably located within the cavity so that when the ball is not contacting the magnetic ring the fishing line may not pass freely through the bobber and guide tube, and when the ball is contacting the magnetic ring the fishing line may not pass freely through the bobber and guide tube.
