Pretty cool gizmo.

I have poor man zeroing process. I use same concept with my Olight Green Laser.

Either rifle or pistol, fire 3 shots, adjust laser to the center of group, walk in rifle/pistol scope or red dot. Repeat until your satisfied.

As long as I remember which way to click, I'm zeroed in few rounds or box of full 50x
