Return of Negative Loft Putter

A new loft angle / Providing a new experience shooting lower scores

PISA started with a question,
“Why does the ball sometimes go in the direction that is not intended when putting?”


We closely looked at the correlation among the initial rotational inertia of the ball, the direction of the force, and the ground fiction. It was confirmed through the experiment that the consistency and accuracy of the ball are closely related to the friction between the ground and the ball.
In other words, we learned that the unnatural movement where balls don’t rotate immediately and skid after putting is the main cause.Based on the result, we concluded that minimizing the initial distortion is the solution to improve accuracy.

“Why do we need to measure the speed of a putting green
with the stimpmeter instead of the putter?”



Golfers may wonder why we need a stimpmeter!
The reason is that the stimpmeter presents a consistent result as the ball rolls from the beginning,but the putter creates unnatural movements in the beginning after the hit, leading to a great derivation of the direction and the distance value.

That’s why we chose the stimpmeter as a certified measuring device to measure the putting green. It’s ironic that the golf world accepted the rolling-type stimpmeter as a certified measuring device instead of the putter being skeptical about the putting accuracy over 100 years.

Unlike the existing putter that causes unnatural skids in the first 15% of the ball movement section, the rolling-type stimpmeter creates a natural rotation without any skids throughout the whole movement without any distortions, providing consistent and accurate measurement values.




Rolling or hitting?


Like so, we developed a way to bring the ideal rotation of stimpmeter to hitting-type putter by devising and investing in various experiment equipment and finally focused on the rotation performance of balls by each loft.

1. We designed the existing positive loft to negative to improve the initial rotation performance of the ball (initial rotation possible)


2. To remove the rotational friction of the putter face, the biggest disadvantage of negative loft, we improved the initial rotational performance after the hit and secured stable movement in a straight line with the use of advanced low-friction materials and the bearing units (180rpm in the initial rotation)


3. Groundbreaking improvement of the rotation performance with a rotation generator making a better movement to the ball than cam actuator, rack and pinion, and hydraulic devices (Achieved 350rpm)


In the end, we successfully found the optimal loft value through several development processes and tests. We completed the development of the putter with almost equal performance to the stimpmeter by improving the initial rotation by at least 1,600% and reaching almost zero in the distortion with an initial rpm of 300 or above.

Under the goal of ‘improving the initial rotation’ of the putter in 2016, we have developed various products through several tests. As a result, we have successfully produced reliable results with the world-class measuring devices such as a 20,000fps high-speed camera, the world’s best putting monitor such as Quintic, and a newly designed precision strike device.

PISA putter with an angle used for the first time in the world
provides you with a new experience!

The Leaning Tower of Pisa is known as the unprecedented architecture with its leaning shape, where Galileo Galilei did a drop test that defied conventional wisdom. The most distinctive feature of PISA putter is the forward-sloping loft. Our forward-sloping loft is in a form beyond our expectations and produces outstanding performance. As such, our brand ‘PISA’ was born with its unique shape and significance in development. By tilting the ‘I’ of the brand name like the Leaning Tower of Pisa, we symbolized its shape as CI.
