Just a follow up on this sight as I finally got it setup right. First off I have to say that I tried to set it up three times and really could not get the performance I was looking for. So I called and spoke to "Lou" who spent a good 15-20 minutes on the phone with me educating me on how the sight works. He explained the speed adjustment and what that affects and then the "midrange" adjustment and what that affects and how the short range stop plays into helping set the trajectory. He also explained that depending on the arrow weight/point weight combination, the sight will have to be tuned to match that. This sight isn't simple to understand right off, but when you do, then you really have a tremendous amount of versatility in terms of tuning the pendulum to your arrows trajectory. With that understanding I was able to setup the pendulum in under an hour with the following results: Dead on at 5 yards, 1/2" low at 12-13 yards, 1/2" high at 25 yards, and dead on at 34 yards. I did not test past this range as that's all we have to work with in my buddies back yard. Shooting the 85 grain Slicks on 5575's, I was shaving vanes at 25 yards, a 4 arrow 1" group. That is not accuracy that I've ever experienced before with fixed heads and I think that it is a combination of the flight characterstrics of the Slicks and also that the round sight guard of the pendulum lined up with the large aperture peep, gives it another reference point for increased accuracy. The thing though that I most enjoyed was after we had it setup was the shooting. I really enjoyed not having to think about range estimation and just focusing on aiming and shooting, what a joy that is. There is a definite learning curve with this sight, but now I really like this sight and would highly recommend it.
