The Ping Anser fairway wood features Trajectory Tuning Technology which allows the player to add or subtract the loft in 1/2 degree increments. The rear sole weighting optimizes the CG to promote a slightly lower, more penetrating ball flight with low spin. This adds distance and elevates the MOI for greater accuracy. The compact 17-4 stainless steel head features a larger hitting surface which elevates the MOI from heel to toe maximizing distance and accuracy across the face.
