The invention relates to an acoustic warning support for stationary fishing casting line, which comprises a control unit (10) with a tubular extension (4), a tiltable support (28), an oscillating supporting arm (37), a mobile rotating arm (21), an elastic lamella (23) fastened with a special screw (22). The control unit (10) has a fixed printed board (11) where there are fastened a vacuum electric contact (16), a stock-protection capacitor (17), a protective diode (14), an electromagnet (13) and a fix electric contact (9). The control unit (10) also has a mobile special axle (27), a helical spring (30), a mobile roller (35), a mobile axle (38), an actuating lever (39) operated by the mobile keeper (45) of the electromagnet (13), a beat buzzer (15) in connection with an orifice (40). The mobile rotating arm (21) is provided with a counterweight (25) that is concentric with a permanent magnet (24). On the tiltable support (28), a sleeve (41) is fixed, supporting the handle (43) of the casting line (20). The tubular extension (4) supports some batteries (5) connected with an elastic electric contact (7), a switch (8) and a fix electric contact (9) of the printed board (11).
