<p>The invention relates to a device that is used to sink bait from a vessel during trolling fishing, characterised in that it comprises a body formed by two arms, namely a vertical arm and a horizontal arm that are attached to the gunwale of the boat. Two pulleys are attached independently to the horizontal arm and can rotate independently of one another, each pulley being provided with a securing wire. One of said wires is used to secure a heavy body and the other wire is used to secure a small sheave joined to a clip which ensures that the bait remains attached to the fishing line while being lowered and raised to the desired depth. When the heavy body is cast from the device, by rotating the pulley thereof, the wire securing same is maintained in a vertical position in respect of the boat. The small clip-fitted sheave is inserted into the heavy body securing wire. The fishing line and bait are lowered by rotating the pulley joined to the small sheave and clip that holds the fishing line steady and, in this way, the corresponding wire is cast from the device. Subsequently, owing to the movement of the boat, the sheave and clip are guided vertically towards the heavy body, which has been independently cast to the desired depth, by the wire securing same. The wire used to secure the small sheave and clip is retrieved by rotating the pulley thereof, such that it rises towards the boat, with the heavy body staying at the desired depth. The invention also includes a direct-current motor having a forwards or backwards rotational movement which rotates the pulley between the wire and the small clip-fitted sheave, thereby transmitting the lowering/raising movement from the fishing line joined thereto.</p> |
