1. An apparatus for evaluating a position of a golfer, comprising:
- a) a first laser adapted to project a first, substantially vertical line forward therefrom;
b) a second laser adapted to project a second, substantially vertical line forward therefrom, said second vertical line being substantially parallel to and spaced apart from said first substantially vertical line; and
c) a third, rotatable laser adapted to project a third line forward therefrom, said third line being selectively angularly displaced from said first and said second vertical lines.

Abstract
A laser-based measurement system for accurately quantifying a golfer'"'"'s stance and club position. The measurement system provides accurate linear and angular measurements. From data gathered by the measurement system, a golf club optimized for the golfer'"'"'s natural stance may be modeled and evaluated. An adjustable club having adjustability in the fourth and fifth axes provided by spherical joints is provided to model a presumed optimal club. The golfer'"'"'s performance using the modeled, optimized club may be evaluated. Finally, a fixture is provided for accurately customizing a golf club along all of the six axes.

13. An apparatus for customizing a golf club in a three-dimensional Cartesian coordinate system having a first (X) axis, a second (Y) axis, and a third (Z) axis and at least a fourth (rotation around said first axis) axis and a fifth (rotation around said second axis) axis, comprising:
-
a) a golf club adjustable in at least the fourth and fifth axes, comprising a head;
a shaft having a proximal and a distal end, said proximal end being swivelably attachable to said head; and
means for securing said shaft to said head during impact of said head with a golf ball during a stroke; andb) a fixture for receiving said adjustable golf club and comprising a scale adapted for orienting said shaft at a predetermined position in at least one of said fourth and said fifth axes.
