I use technology as a complement to my eyes and gut. I also spray the face of the club to track face mapping and be sure contact is center. Vertical and horizontal gear effect can mislead our eyes. If the strike is toward the toe, for example, tech read will recognize open face but of course the flight will be hook. This is quite a different revelation than a face open to the path when struck in the middle. So be careful
