To focus one's aim; to zoom in and center on something

To find the path to the pocket, usually after some poor hits and/or experimentation
adjust (as by firing under test conditions) the zero of (a gun); "He zeroed in his rifle at 200 yards"
Find the right strike spot on a lane
direct onto a point or target, especially by automatic navigational aids
nullify; direct; concentrate
