Ref.2 clearly mentions that: “The advantage of this design over that of the preceeding example is that it concentrates the majority of the weight of the device in the shaft .”Column3, lines 37-40.
Thus, the inventor of Ref.2 teaches the laser must be on the shaft,which implies that the laser must be not on the putter head(高尔夫击球推杆杆头),only reflecting optics must be on the putter head.Our invention is opposite to the teaching of Ref.2.
