I a friend of mine bought one several years ago and it turned out to be a waste but who knows ymmv!
Ain't that the truth. last time I went bow hunting. I thought I would be smart and put one of those blunt rubber "small game" tips on one of my arrows. That way(I thought) if all I saw was squirrels, I would be ready. Sure enough, the only critters to make a showing that day were the bushytails. After I got fed up with waiting for a deer, I grabbed the blunt arrow and let fly at a squirrel on a branch not 10 feet away. Arrow nailed the little sucker right in front of the shoulder, knocking him to the ground... from where he promptly ran right back up to the same branch I knocked him off of and proceeded to scold me while I went looking for my arrow.Best thing I've found to find squirrels is go to deer hunting. Never fails.
