I just purchased a Copper John Dead Nuts Pro sight and a Scott Little Goose release. Some of the best " investments" I have ever made. The Little Goose helped me cut my group size in half! I was using a tru-fire x-caliper before. Good results but just not as good as the little goose. And as for the Dead Nuts Pro, I can' t say enough about it, a tough sturdy solidly build piece of equipment, and man do those little.019 pins glow, it is almost like someone has a light on them even though I don' t have a light on the sight. If anyone out there is looking to buy a new sight or a release I would deffinitly suggest they take a look at these two products, They are in the mid to high range when it comes to cost but they are worth every penny. I understand now why almost anyone who is anyone in the bowhunting and archery world uses Scott releases, man they are great.
