ABSTRACT:
A powered line fishing device, which can also be used as a vacuum or a blower. The device includes a thin-walled container having a bottom, side walls and a mouth. A top plate is positioned over the mouth and an intermediate plate is positioned in the thin-walled container between the mouth and the bottom and is adjustably attached to the top plate. The vacuum/blower unit is positioned between the top plate and the intermediate plate. When the assembled top plate, intermediate plate, and the associated vacuum/blower unit is inserted into the thin-walled container, the intermediate plate seals against the inside surface of the walls. The intermediate plate provides support to prevent the thin-walled container from collapsing when the device creates a vacuum. The vacuum/blower unit, retained between the top plate and intermediate plate, are retained entirely within the thin-walled container to protect the vacuum/blower unit and lower the center of gravity of the device to provide greater stability.
