I supposed it depends on where you're hunting and the terrain. From a tree stand, most guys will never need the "ARC" unless they hunt ridges, and intend on shooting down a LONG ways. That being said, I'm one of the guys who hunts some places where it would be beneficial, yet I've not yet ponied up the $$$ for one. Elk hunting in mountains would be a prime example of where one would be beneficial, yet at the same time, when the size of the kill zone it 2-3x that of a deer, then I think we start wondering whether it's really that useful. I DO believe that it IS quite useful, but that is just my opinion.
