I used one of these sights for about 8 to 10 years. This sights are not meant to be accurate from the ground while unlocked. They can be locked down to be used as a fixed pin sight although you must lock it down in one of the notches so you can really lock it down exactly where you want. They are a little noisy but that never cost me a deer. I now shoot the trophy ridge site and love it and I don't have to practice off the ground all the time or worry about how high I am in the tree. They are good sights but they have tradeoffs.
