The Groupy measures groups within a 1.5” diameter. Measurements are laser cut into acrylic with a glow-in-the-dark cord attached.
Shoot three to five shots. Lay Groupy over shot group. Adjust until one of the circles cross the center of the two outer most holes. Read measurement on that circle to determine group size.
