For the most precise long-range shooting, use the bubble level to ensure that the crossbow or rifle is perfectly vertical. This will eliminate potential errors.
The Vortex Bubble Level mounts quickly and easily to the riflescope tube. For best results, mount on the opposite side of your dominant eye.
