Introduction
3BaysGSA PUTT is a patent pending innovation in golf Putting technology. It records your Putting motion and sends
the information straight to your mobile phone through its unique GSA PUTT app, which compares each Putting
against your own or your instructor’s best Putting for greater accuracy.
The following table lists out the definition of some specific names using in this manual.

Description
Consistency
It compares all aspects of each stroke just played with the best record and shows you how repeatable
your putting stroke is. (in %)
Face angle
On GSA PUTT app, it shows both the putter’s face angle at impact and face angles along the stroke,
relative to address. + means Open and - means Closed. For right-handed golfers, Open is when the
face is pointing out to the right and Closed is when the face is pointing out to the left. It is opposite
for left-handed golfers.

It is the vertical (up-down) angle at which the putter head is moving at impact, relative to address.
+ means hitting up on the ball, while - means hitting down on the ball.
Tempo
It is the ratio of backswing time to downswing time. For example, 2.5:1 means your backswing is
2.5 times slower than forward swing.
Backswing time
It is the time taken of your backswing from address. It can be shown up to 2 decimals of a second.
Downswing time
It is the time taken of your forward swing to impact. It can be shown up to 2 decimals of a second.
