Abstract: A device supporting the arm of a fisherman using a spinning-type fishing rod having a cylindrical rod handle, comprising an adjustable rotatable arm cradle supporting the upper forearm of the fisherman, a partially cylindrical elongated handle support member defining a partially cylindrical compartment that holds a selected area of the fishing rod handle in alignment with the arm cradle, an adjustable post connecting the arm cradle means with the handle, and an adjustable clamp for removably gripping the rod handle to the handle support. The arm cradle is rotatable to a selected angle relative to the rod handle and is removably lockable at the selected angle. The connecting post can be lengthened or shortened to a selected position and removably locked at that position. The clamp that presses the fishing rod handle against the top of the holding compartment of the handle support member is adjustable by means of a vertical screw that raises or lowers the clamp.
