Good pendulums are good sights. However, you cannot cut corners on cost.

Check out the ABC pendulum sight. I shot an earlier version and was very impressed. Previously, I had owned several other brands, but none were as good as the ABC. I do not know how good the new model is. Sounds like it is much improved.

I am shooting a 1-pin setup (static sight) this year. However, I keep going back and forth as to whether I should have installed a good pendulum. Experience has shown that a good "swinger" does assist the one constant that all bowhunters face; distance estimation.
