I don' t mean to sound as if I don' t think the pendulum sights " work." It' s just a definition of " work" . I' ve never used one, but I know they' re not " magic." I' m not familiar with the claims the manufacturers make, but the functionality of the sight HAS to be a " close enough" and not an " exact" at every distance (just like the one pin I use for " every" range shot.)

I know this because, for instance, the angle that the bow is held for a 25 ft (8.3 yd) distant shot from an elevation of 10 ft is the same angle the bow is held for a shot 100 ft (33.3 yd) distant from an elevation of 40 ft (assuming perfectly level ground.) The position of the pin on both shots is the same, because the pendulum always hangs straight down. And, I know from years of archery shooting that a pin cannot be positioned to hit " dead on" at 8 and 33 yards simultaneously. Therefore, I can safely say that someone could not shoot the these two shots mentioned, while placing the pin directly on the bullseye, and have the arrow impact at the exact same spot on each target.
