Purchased 2018 and goes with me into tree for rigging
by John -
It is light enough to carry into tree any time I need to rig above ground. It is strong enough for most negative blocking I do as well as some limbs that need to be dropped into redirects. Opens and closes easily with no loose parts and is easy to examine for proper line routing.
