In an ideal world, the laser would come out of the #3 pressure point and shoot through the line of pull (sweetspot). If the laser is close enough to the #3 pressure point, shooting straight down the shaft can suffice.
Ted: Thanks for that. So am I correct in thinking that the laser should point slightly outwards and above the base line in the followthrough about 1 1/2" or so? Can you describe precisely how you should use the laser in the post impact stages of the swing? I want to get this right.
