The Radi-Eye Challenge

The Radi-Eye. Most forgiving putter ever made.

We could explain the curved face and the test numbers and all of it. But you don't know us, so why would you believe any of it.

Run the putts instead.

The Challenge

Your putter vs. the Radi-Eye.

Bring your Scotty. Bring the putter you have used for ten years. Bring whatever you swear by. We don't care.

20 putts with yours. 20 putts with the Radi-Eye. Same hole, same distance, same spot. Whoever makes more wins. That is the whole pitch.

For the record, an independent test at Edwin Watts had the Radi-Eye 40 percent more accurate on 10 foot putts. Nice number. Now forget it and go count your own.

HOW IT WORKS

A Different Face. A Different Approach to Impact.

Conventional Putter

One Overall Orientation

A flat face has one overall orientation. When that orientation changes, the ball's initial direction can change, too.

Radi-Eye

Local Orientations That Vary

A curved face has different local orientations across its surface. Radi-Eye uses this geometry in an effort to reduce the directional effect of face-angle errors.

Instead of relying entirely on presenting one flat surface at precisely the right angle, Radi-Eye introduces a different geometry at the moment of impact.

The intended benefit is greater forgiveness of face-angle errors when starting a putt.

FAMILIAR GEOMETRY

You've Seen Curved Clubfaces Before.

In the Bag

Drivers use curved faces, known as bulge and roll, to influence how off-center impacts behave.

On the Green

Radi-Eye brings the broader curved-face concept to putting, where the goal is to influence the ball's starting direction at the moment of contact.

The difference is that a driver sends the ball into flight, while a putter sends it rolling along the green. Radi-Eye is built around the idea that face geometry can matter at the instant a putt begins.

A familiar engineering concept. Applied to a different part of the game.

THE EVIDENCE

A Different Design. A Specific Performance Goal.

Radi-Eye focuses on one particular challenge in putting: the effect of face-angle errors on the ball's starting line. The historical evidence reported for the product includes an independent test, media coverage, and a professional analyst's testimonial.

Independent Test

The 2010 Test

According to the reported results of an independent test conducted at an Edwin Watts facility in 2010, Radi-Eye measured 40% more accurate from 10 feet than the other USGA-conforming putters included in the comparison.

Media Coverage

Radi-Eye was featured in ESPN's 2012 holiday gift guide and received coverage in USA Today.

Testimonial

Michael Collins

ESPN analyst Michael Collins reportedly said:

I don't know how it's possible either, but I've seen it in person and it works.

A Classic Blade. An Unconventional Face.

Radi-Eye combines a traditional blade profile with a curved, precision-milled striking face. The design changes one central element of the putter: the geometry of the face. The result is a distinctive piece of golf equipment built around a specific approach to starting-line forgiveness.

The Details

Design: Classic blade
Face: Curved, milled
Material: 318 stainless steel
Head Weight: 360 grams
Length: 34 inches
Shaft: Full offset
Lie Angle: 70 degrees
Loft: 0 degrees
Conformity: Reported as USGA conforming
Assembly: Concord, North Carolina

Zero-Degree Loft

Radi-Eye uses zero degrees of loft as part of its design approach to promoting forward roll. Actual launch and roll behavior also depend on impact conditions and the putting surface.

The Bottom Line

Every other putter has a flat face. Flat faces punish small mistakes. Yours does it too, you just got used to it.

The Radi-Eye was built to forgive the mistakes every flat face punishes.

20 putts will tell you if that is true. Not us. The putts.
