The invention relates to an acoustic trolling gear comprising a shaft 1 with a fastening device 2 for the fishing line 3 and hooks 4. It also comprises devices 6,12, which can be advanced to some extent along the shaft close to one another, and which are fitted with grooved surfaces 9,13 facing one another. One of these organs is formed like a double wing 6, which does not rotate as the trolling gear travels through the water, while the other organ is a spiral body 12, with flanges going into the spiral, thus permitting a rotary movement at the spiral body. Since the grooved surfaces 9,13 touch each other here, a clicking, snapping or similar sound is produced. The trolling gear is equipped with a replaceable weight 5, made e.g. of lead, to compensate for the tilted trolling of the fishing line. <IMAGE> |
