I can attest to the reality that this little clown saw works just as well 45 feet up* a hemloc, hanging from my belt on a 4 foot rope tether, just as well as it does on the saw buck!
I did "reach the short end of my rope" trying for one more branch, but a quick flip of the tether cleared that.
Light as the saw is, cutting 20 or so limbs, with me supported by a linesman's belt and spikes is about all I can put together at one stretch. It was easy to know when it was time to spike down.
Lots of limb rounds for the evening fires on these autumn nights
Ground work went REAL FAST with that little fella!
* is that 45 feet AGL? ;-)
