I had it happen to me and I swore I would never hunt out of I tree stand I didn't put up my self. The pendulum never swung it was lying flat and here is this trophy at 18 yds!

Don't get me wrong for the time that I used it it was nice not to have to judge the distance so to say. I now have a laser rangefinder and I always range the distances from the stand each & everytime I'm in them. So I know every how far branch rock, etc is.

Let me know how the experiment goes.
