GC2 directional calibration

I would appreciate anyone explaining how the GC2's direction is calibrated indoors. Outdoors, I imagine it would be easy as you could adjust based on the flight of the ball in relation to the target. Indoors, using the ball flight is not really possible. Is it just a matter of guessing where to point the machine?


Many thanks

Parallel to the direction you swing, perpendicular to the screen. It is rectangular. Unless you have a laser or something you'll be off a little bit but shouldn't matter too much.

The new protector cover has a means of attaching an alignment rod (or laser of you are that way inclined)

Ok thanks!
