Angle of Attack
The vertical angle of the club head's path at the moment of impact, measured relative to the ground. A positive angle of attack means the club is moving upward through impact (typical for driver swings); a negative angle means the club is moving downward (typical for iron swings).
For a driver, optimal angle of attack is typically +1° to +5° (slightly upward) to maximize distance and reduce spin. For irons, a negative angle of attack of -2° to -5° produces clean ball-then-turf contact.
Angle of attack is one of the more meaningful metrics for serious players because it's a primary lever for distance optimization. Not every launch monitor measures it directly. Among launch monitors in our catalog, the Rapsodo MLM2PRO, Square Golf Omni, Bushnell Launch Pro, Foresight GC3, and Uneekor EYE family directly measure angle of attack. The SkyTrak family does not.
