Abstract
An impressionable medium, such as a element 56, is secured to an impact face 30 of a head 22 of a golf club 20. Alterations, such as grooves 46, are formed in a surface 42 of a target object 40. The object 40 is placed on a level surface such as a surface pad 64 with the grooves 46 being perpendicular with a plane of the pad and positioned for being struck by the element 56 and the impact face 30. Impression lines 66 are formed in the element 56 by the grooves 46 when the club 20 is swung and the head 22 strikes the object 40. Impression lines 66 are a representation of the angular relationship between a bottom 34, or grooves 32, of the head 30 and the plane of the pad 64 at the instant the element 56 and the impact face 30 strike the target object 40. This representation can be used to determine the dynamic lie of the club 20 at the instant the target object 40 is struck.
