Putting Fitting in the SPOT-Light

One putter I am so proud to introduce is SPOT whose acronym is short for Stroke Path Optimization Technology. Yes, that sounds like a mouthful, but based on the feedback from attendees at the PGA Merchandise Show, this is going to be a huge hit amongst clubmakers and club fitters alike.  Unlike most putters on the market, this putter can actually adapt to the golfer’s putting stroke.

First, we took the most popular putter style out there and then adapted it to allow for 3 different hosel positions.  Here are the reasons why.  First, hosel position in relationship to the clubhead’s center of gravity has a pronounced effect on whether the putter is face balanced or if the toe hangs and if so by how much when the putter is allowed to rotate freely along the shaft’s axis.  Secondly, the toe hang of a putter should be matched according to the path of the golfer’s stroke for the most accurate results.

Toe Hang or Gravity Angle
Let’s take a quick look at what causes toe hang or what is also referred to as gravity angle.  We first need two dimensions.  The one labeled A in our diagram is the center of gravity or CG offset of the head from the center line axis of the shaft in the heel-to-toe direction.  The other dimension is B or the CG offset of the head from the center line axis of the shaft in the face-to-back direction.

If A in our example is 0.29” and B is 0.66”, then the toe will hang 23.7º.   This is simply the byproduct of the arc-tangent of the A/B ratio. By moving the position of the hosel closer to the center of the face or more toward the heel, we are able to adjust the gravity angle.

The SPOT putter with the hosel in the most forward position comes closest to a face balanced situation as the center line axis of the shaft (A) passes nearest to the CG of the head.  The middle and rear two positions create additional toe hang with the more prominent amount in the heel position.

Putting Path
There are three basic classifications for describing a putter’s path.  These are commonly referred to as straight back – straight through stroke, a slight arc and a pronounced arcing path.  And each type requires a different amount of toe hang for best results.

Year in and year out, the Anser-style putter has stood the test of time.  The toe hang on this style putter usually averages around 35º, while most golfers have a slight arcing path.

Face balanced or nearly face balanced putters are suggested for golfers who possess more of a straight back – straight through path and finally golfers who have a pronounced arc path generally prefer heel-shafted putters.

The SPOT putter is able to accommodate all types of strokes with one body style.  All you need is a 4mm Allen wrench and you can easily see for yourself on the putting green.

Hosel Configuration
In addition, the SPOT putter is available in 3 different hosel configurations. There is a plumber’s neck featuring a full offset, a slant neck or half offset model and lastly a straight neck producing no offset at all.

The varying offsets also contribute to the amount of toe hang.  Plus offset is what controls direction with less offset being more prone to hitting the ball more to the right of their intended target line for a RH golfer.

For instance, if you have a tendency to pull the ball you might be better off with the straight neck. If you hit the ball pretty straight you might consider the slant neck.  Lastly, if you push a lot of putts, the plumber’s neck may be the best choice.

Putter Fitting
For professional fitters, I would encourage you to shaft up each of the hosel adapters with the same length shaft and same type grip and head off to the practice green with your customers.

With one head and 3 adapters, you have essentially 9 putters that you can interchange adapters and the hosel positions until the player sees the most repeatability for themself.  In 15 minutes or less, your customer can walk away with their recently fitted putter.  Remember, the putter accounts for 40% of all strokes taken meaning this should be the starting point of any fitting.

Even if you aren’t a professional fitter, with a little patience you can still fit yourself for the hosel type and position which provide the most repeatable results and toward lowering your score.

Paws for a Cause
Lastly, for every SPOT putter sold this year, a portion of the sales is going to be donated to our local animal shelter to help a fellow Spot.

    Pretty amazing concept (for putter fitting and adjustability)in a golf world where Driver adjustability is now the norm. You did a great job explaining all the factors that we should be considering when fitting a putter. Thanks for that.

    Do you have any plans for a mallet-style or high MOI type head in the works? I know the blade style is probably the most used on the tour, but most of the guys I play with (myself included) have transitioned to a larger, higher MOI type putter head. If this becomes a good seller for you maybe the next logical step would be to add removable weights giving us the ability to offer a heavier or lighter putter to our customers to even further customize the fit.

    Thanks for all the innovation Hireko continues to provide.

    Jeff or anyone who can answer: GREAT PUTTER, is it approved for USGA Tournament Play when asembled with the ADJ. HOSEL; or is it just for FITTING??? Thanks FRANK

    “One putter I am so proud to introduce is SPOT whose acronym is short for Stoke Path Optimization Technology.”

    I am “stoked” over the release of this head too.
    I’m sure you meant something else.

  4. Jeff Summitt says:

    Frank:

    The SPOT putter meets all the requirements for adjustability in the Rules of Golf. It was intended for both play and fitting.

  5. Jeff Summitt says:

    Mike:

    I have tons of ideas, it is just a matter if a product will sell. We want to see how well the blade does before introducing a mallet style.

  6. Any plans on introducing an adjustable putter shaft to generate a regular, belly and chest style putter? gc

    the best inovation in golf since the 460 driver heads—–a tip of the hat to you

  8. Bud Villalpando says:

    What about the material on the face ? What is it ? Does the ball come off soft, med, or hard ? Is it variable ?

  9. Jeff Summitt says:

    George:

    I have been working on something for longer putters but not sure when we will pull the trigger.

  10. Chuck Prickett says:

    Great Idea. Now all we need is a connection system where we can change the shafts like they do with the Drivers. I currently keep switching between a standard length putter and a Belly. Sure would be nice to unscrew one shaft and replace it with another without having to regrip.

  11. Jeff Summitt says:

    Bud:

    The face is 431 stainless steel – no soft inserts. Then again, almost all balls have a soft urethane cover.

  12. what is the weight of the putter head?

  13. Jeff Summitt says:

    Illona:

    The weight of the body, hosel and screws is 355g.

  14. Heel-toe weighted putters (for example, a Ping Anser 2) hang at a 45 degree angle (4 o’clock) to the ground.

  15. GLENN B. says:

    WHAT METAL IS THE HOSEL MADE OF 304SS OR 431SS OR OTHER? IS THE HOSEL BENDABLE FOR LOFT AND LIE ADJUSTMENTS? THANKS FOR A GREAT DESIGN FOR BOTH PLAYABILITY AND FOR FITTING, LOOKING FORWARD TO RECEIVING THIS PUTTER AND HOSELS.

  16. Jeff Summitt says:

    Business Review:

    45 degrees is an over simplification. 4:30 would be 45º and 4 o’clock would be less than that or 30 degrees.

  17. Jeff Summitt says:

    Glenn B.

    The hosels are made of 431 stainless steel. Bendability will depend upon how surely you can clamp the head and the tools you have to bend them. Remember you are relying on the screws to do the same thing as if the hosel was cast as part of the body.

  18. Mark says:

    I bought the Spot Putter and slant neck hosel and am completely satisfied. It took a little persuading to get the shaft and grip installed by Hireko (stepless steel with Jumbo Winn grip) but I can already see a difference in how I stroke the putter and the new found accuracy to the target. Great putter would highly recommend it!!!
