Abstract: The invention relates to a fishing rod accessory having simple design which is connected to a traditional float (1). As a result, a cast bait can be lifted or lowered, as if by remote control, by corresponding movements of the fishing rod. The inventive accessory consists of a hollow body (4) which can be rapidly flooded via the two end openings (for the fishing line (3) to be passed through), and a (submersible) ball (6) lodged inside the hollow body (4). Said ball (6) frees the passage of the line (3), when the hollow body (4) is in horizontal position, by rolling into a trough-shaped hollow, whereas it blocks this passage after swinging around an axis (5a) (i.e. in vertical position) by jamming, together with the line, in the circular and funnel-shaped outlet opening, when the position in question is stabilized (until the next fishing rod) manoeuvre).
