Abstract: A device used to sink bait from a vessel during trolling fishing, includes a body formed by 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 wire 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. The small sheave is inserted onto 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.
