A launch monitor is a tool capable of measuring these three parameters.
The cheaper camera or laser-based launch monitors then use this information
to predict the ball flight on a computer screen. This has limitations.
At the St Andrews Links Golf Academy the AGT staff use a top-of-the-range
ball flight monitor called Trackman which, instead of trying to predict
the ball flight, actually tracks the path of the ball in the air, giving
exact yardages and shot shape. It does this by using sophisticated Doppler
radar technology, similar to the systems used by the military for tracking
ballistic missiles. At last we have a tool which takes the
guesswork out
of test hitting. We can now measure
distances to an accuracy of 1-2 yards.
The tour pros have been making full use of this new technology
in recent years to select and customise their drivers. However this
technology is not just a fitting tool for the elite player. Slower
swinging amateurs can also benefit from a launch monitor session. A
common problem for many of these players is that they are unable to achieve
a high enough launch angle or spin rate from standard lofted drivers, and
as such are losing precious distance off the tee.
