I have been using this for a number of years and decided to do this short review. For many years I used a set of calibers which was better than a ruler but still difficult to accurately find the center of holes. With this tool it is much easier because you only need to locate the outside edge of holes at the extreme edges of your group. I have found using a backing piece of paper beneath the target helps but not totally necessary.
