    • 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.
    • 诸如元件56的可印象的介质固定到高尔夫球杆20的头部22的冲击面30上。在目标物体40的表面42中形成诸如凹槽46的变化。物体40是 放置在诸如表面垫64的水平表面上,其中凹槽46与垫的平面垂直并且定位成被元件56和冲击面30撞击。印模线66由元件56中的凹槽形成 当俱乐部20摆动并且头部22撞击物体40时,印模线66表示头部30的底部34或凹槽32与垫64的平面之间的角度关系 元件56和撞击面30撞击目标物体40.该表示可用于确定在目标对象40被撞击的瞬间,球杆20的动态位置。
