A fishing line release mechanism has a permanent magnet positioned within a housing with the poles of the magnet arranged to draw a magnetic release plate toward, or into contact with, the magnet. The release plate has a buttonlike configuration with a central aperture which enables the plate to be threaded by a fishline. When a fishline threaded through the magnetic plate aperture is looped several times around the plate and the plate is then positioned in proximity to the permanent magnet, the line cannot unreel until considerable tension is applied to it. The tension limit can be preset. When the preset limit is reached, the buttonlike magnetic plate springs away from the permanent magnet to release the fishline to further control by the reel.
