Produces A Superior Read to Old
Lie
Board Technique
The
most common device currently being
used to make lie angle measurements
is the “lie board”. A strip
of masking tape is attached to the
sole of the club and a ball is then
placed on the lie board and struck
with the club.
If the club makes contact with the
lie board, a mark is left on the tape
and the location of the mark gives
a rough indication of whether the
lie angle at impact is correct, too
flat or too upright. The accuracy
of this technique is a function of
the ability of the clubfitter to correctly
interpret the position, size and shape
of the mark on the tape and how it
relates to lie angle.

Unfortunately, these marks are affected by
factors other than lie angle: Fat hits, thin
hits, differences in curvature of the sole
between various clubs, and clubface angles
that are closed or open at impact all have
an effect on the mark.
Because of these variables, it is often very
difficult to determine accurate lie angles
and the testing procedure can become tedious.
If a club lie is incorrect, it is quite difficult
to determine the exact angle of adjustment
needed from a sole tape mark. Also, the golfer
being tested is required to hit a fat shot
off a hard plywood or plastic surface in order
to produce a useful mark on the sole tape.
This can be intimidating and result in an
unnatural swing which further clouds the validity
of lie board data. Lie boards are used only
for iron club measurements; the sole of a
wood club is usually too flat to produce a
useful lie mark. |
