[quoteYes, they do use long poles to use them from tree stands. There is an old hunting video floating around out there made by a treestand manufacturer from back in the 80's where they kill several bears this way on camera. I remember the spear is probably 10-15' long, and has a long 12"ish double edged blade on the end that they stuck straight down through the shoulder blades of the bears from directly above.][/quote]

Yep- I remember watching that video. When those bears got stabbed with the "spear" they let out some nightmarish growls.
