Two people standing far apart would work well with a saw of that sort.

1) Hardly necessary. You put one rope end in each hand and work back
and forth. With two folks you often end up fighting each other because you
get out of sync.

2) You can stand well to one side with this gadgets. It make not be 100%
safe but a lot better than climbing the tree or being on a ladder.

3) The one I had looked like 3' or so of "chainsaw" chain. It had a
metal tab on one end so that it rotated to keep the cutting edge down. One
end of the line had a small "sand bag" attached so that you could throw it
over the limb to get things started. I think I paid almost $40 at Sears.

I'm in my mid 60s so it had taken me a fair amount of time to cut things
using these gadgets and, therefore, I have been tempted to use the ladder
and some power equipment. But if you don't use power equipment they are a
reasonable alternative to actually getting up in the air by some means. A
younger person in good condition (and gloves to keep the narrow line from
diging into his hands) could get a lot of use from these gadgets.


Extention poles just don't "cut it." In the real worl in real trees, you
often want to cut something over20' in the air. You also end up being in
greater risk of having the brance hit you on it's way down as you lost the
advantage of the long extension when you step to the side.
