Abstract: A device for placing a work line into a space that is normally difficult-to-reach, comprising a tubular handle having a locally terminated distal end and a hand-gripped slingshot attached to a butt end of the handle. A spool of a pull line attaches to the handle. The spool is selectively operated for freely releasing the pull line from the spool and for rewinding the pull line onto the spool for pulling a work line into a remote space which is difficult to reach. A weight attached to the free end of the pull line is fired by the slingshot into the difficult-to-reach space to move the pull line thereinto. A work line is secured to the pull line and pulled into the difficult-to-reach space. Embodiments of a traveller for connecting the pull line to the work line and for guiding the engagement of the pull line and the work line upwardly into and through an upper portion of a tree.
