Another breakthrough putter design idea from the innovation originator, PING, is in the Sigma 2 putter family. Notably, these putters have improved feel and are even adjustable. The lineup offers a variety of shapes, ranging from the classic Anser to some brand new models to suit any golfer. We give you a closer look at what’s new on the Sigma 2 putters and introduce you to the models and finishes that are available.

Sigma 2 Putter Innovations

Feel

It goes without saying that feel is extremely important in a putter. In the Sigma 2 putters, PING combines a soft feel with the responsiveness for consistency usually found in firmer-feeling putters.

To accomplish this, PING uses a new Dual-Durometer PEBAX material for the insert. The insert consists of two layers, one soft and the other firm. The softer front layer (think pencil eraser), provides an extremely soft feel for short, delicate putts. The firmer back layer (think tire tread), provides the solid feedback and distance control needed for longer putts.

The face of each Sigma 2 putter features PING’s patented TR face pattern. The depth of the pattern varies, deeper in the middle and shallower as you move toward the heel or toe. This design speeds up off-center hits, providing more consistent ball speed on all putts.

Adjustability

“ALONG WITH THE NEW FACE DESIGN THAT’S BOTH VERY SOFT AND RESPONSIVE, WE’RE PROVIDING GOLFERS THE ABILITY TO CUSTOMIZE THEIR SHAFT LENGTH BY INTRODUCING A SIMPLE AND INTUITIVE ADJUSTABLE-SHAFT-LENGTH TECHNOLOGY THAT IS A STANDARD FEATURE ON EVERY PUTTER IN THE LINE.”

—JOHN K. SOLHEIM, PING PRESIDENT

Adjustability is nothing new for PING, previously offering it in the PING Nome putters. The Nome was adjusted using a tool in a clamp-like ring around the shaft. While functional, it wasn’t very easy to use. To loosen, you had to turn it counterclockwise and lining the grip square again was often a challenge. PING engineers addressed these issues in an incredible way.

Every Sigma 2 putter has a USGA-conforming adjustable length shaft. This allows you to adjust the length of your putter from 32 to 36 inches quickly and easily. Unlike past iterations of adjustable putter shafts, a screw inside the shaft is adjusted from the top of the grip with an adjustment tool. A full turn of the tool alters the length approximately ¼ inch. This allows the length to be changed quickly without the prior risk of the grip ending up not square. Because the mechanism is inside the shaft, changing the grip won’t limit your ability to adjust the length.

PING Sigma 2 Models

The Sigma 2 line comes in 9 different models and 2 finishes, Platinum or Stealth. Meet the models:

Anser

This classic blade putter is the only Sigma 2 putter that comes in both Platinum and Stealth finishes. As with past Anser putters, the Sigma 2 Anser has a plumber’s neck that fits golfers with a slight arc in their stroke. The familiar single alignment line on the back flange of the putter helps with alignment. A medium, 350-gram head weight, 70-degree lie angle, and 3 degrees of loft complete the stock specs.

ZB 2

The Sigma 2 ZB2 is a blade putter with a flow neck hosel. At address, the ZB2 looks like a smaller, rounder Anser (with a different hosel, of course). Despite its smaller size, ZB2 packs the same amount of MOI as the Anser thanks to an improved design. The center cavity is cut deeper, allowing more weight to be placed on the perimeter, upping the MOI by 25% over the previous model.

The ZB2 has a generous amount of toe hang, perfect for a strong arc putting stroke or if you have a pull tendency. The putter head weighs the same as the Anser (350 grams) and has the same standard loft and lie angle (3 and 70, respectively).

Arna

The Sigma 2 Arna is a new, mid-mallet design that comes in the sleek Stealth finish. The head weighs in at a slightly heavier 360 grams. This extra weight helps deliver a smooth, confident stroke on short putts without sacrificing distance control on lag putts. Lining up putts is a cinch thanks to the long alignment line on the back.

The flow neck hosel gives the Arna a moderate toe hang, which fits a slight arc stroke type. The standard loft is 3 degrees and the lie angle is 70 degrees.

Kushin C

Sticking in the mid-mallet category, next up is the Sigma 2 Kushin C, available in the platinum finish. The Kushin line reemerged last year with the Sigma G Kushin, a heel-shafted, wide blade putter and can be built to suit either a straight or arced putting stroke. The Kushin C mainly varies in looks, notably being center-shafted. This fits golfers with a straight putting stroke.

Another difference is the multiple, smaller lines that pair with the main alignment line on the back of the putter. The additional lines further help with alignment.

The width of the Kushin C is about the same as the previous model. However, the Kushin C has a notchback look, making the putter increasingly stable by placing more weight by the heel and toe.

Fetch

Another new putter model is the Sigma 2 Fetch. This is arguably the most interesting looking model in the Sigma 2 putter line for a couple of reasons. First and foremost, is the hole in the middle. The hole not only pairs with the 2 alignment lines to help you aim, but it will also pick up your golf ball. Also, the unique shape of the head fits inside the hole so you can grab the ball with your putter after sinking that long putt.

On the technical side, the head weighs slightly more, tipping the scale at 365 grams. It comes in the clean platinum finish and fits a straight-back-straight-through putting stroke.

Tyne

PING brings back the popular Tyne model for the Sigma 2 line. The Sigma 2 Tyne, available in the stealth finish, has a familiar “fang” design, found in other popular putter models. The design’s popularity comes from its performance. The shape frames the ball nicely and boosts MOI  for extra forgiveness.

The alignment line on the Sigma 2 Tyne is moved to the back of the putter (versus being on the top of the Sigma G Tyne). The line pairs with micro-lines and the “tines” to easily line up putts.

The heel shafted head can be custom built to fit either a straight or slight arc putting stroke.

Tyne 4

Looking down at the Sigma 2 Tyne 4, it’s easy to confuse it to the Sigma 2 Tyne. Both have the same overall shape, forgiveness, and alignment features. Besides the different finish, the Tyne 4 has a different hosel, which is a short, flow-neck hosel. This gives the Tyne 4 more toe hang, making it better suit a player with a strong arc in their putting. The head of the Tyne 4 is also slightly heavier (5 grams), giving it a little extra stability.

Wolverine H

The Sigma 2 Wolverine H also received a makeover versus the previous model. The view from above looks like a cross between the Sigma G Wolverine T and a Craz-E. To us, the Wolverine H helps line up the ball easier.

The hosel is also different on the Sigma 2 Wolverine H, resembling a plumber’s neck. This gives the putter a mid-toe hang, fitting a slight arcing putting stroke.

Valor

Last but not least, meet the Sigma 2 Valor. This full mallet is a new model for PING. The squarer look pushes more weight to the perimeter, increasing the MOI/forgiveness. The large area in the middle makes alignment super easy too. The heel-shafted head can also be customized to fit either a straight or slight arc putting stroke.
