I wonder if our answers might be misplaced on this; this is largely a site visited by professionals who know how to saw a limb off safely because they are doing it tens to hundreds of times a day (excluding me, I drove the hearse), and this device looks like it is an intended solution to all those Youtube videos of amateurs at the top ends of ladders getting knocked to the ground and seriously injured as the limb comes off. What is the impression of a professional arborist of this device with those weekend-chainsaw-warrior-arborist videos in mind?--maybe it has merit in that light, in an application where time is not money and being at the saw when the limb goes is obviously dangerous.
