The Puttronome ™

Harold Swash Putting School in conjunction with DXP Tech LLC is pleased to bring to you ‘The Puttronome™’

‘The Puttronome™ is an Audio/Visual-based iPhone App that is designed to help golfers train their tempo and distance control.

To understand how the Puttronome works lets first of all understand the importance of tempo to control distance and the limitations of other methods.

Distance control, the key to putting

Putting consists of two main parts, distance and direction.  Distance control therefore, or the ability to roll a ball a specific distance, is the most important attribute of putting.  Consistent distance control is what separates good putters from bad ones.

What are the factors involved in distance control?

Tempo drives distance control and is the “engine” of the putting stroke.  Tempo is the timing of the overall rhythm of the putting stroke.  Being able to execute a proper stroke, time after time with consistent tempo is the key to distance control.

Characteristics of a proper putting stroke

  • The swing length varies for different distances while the timing does not
  • The backswing length determines the distance the ball rolls
  • The backswing time is approximately equal to 2.1 times the downswing to impact time
  • The backswing/downswing tempo should remain constant regardless of the swing length
  • The follow through length is roughly equal to the backswing length or just a fraction longer
  • The downswing stroke’s has a constant rate of acceleration into impact as opposed to a pendulum that has a decreasing rate of acceleration.
  • Overall putting motion is smooth but has a distinct acceleration on the downswing

What are some drills to practice consistent tempo?


  1. Swing the putter back and forth from the top of the backswing to the top of the followthrough keeping the same rhythm.  Use a Metronome set to a comfortable tempo in which the “tick” occurs at the top of the backswing and the “tock” occurs at the top of the followthrough.  Keep the same tempo while you shorten and lengthen your stroke.  A good starting point for most is around 90 beats per minute.
  2. Now, for a putting stroke, start the putter back on the “tick”, reach the top of the backswing on “tock”, execute the downswing and reach the end of the followthrough on the “tick” with impact falling between the “tock” and the final “tick”.  However, after a few repetitions, you may find that you are striking the ball on the final “tock” instead of reaching the end of the followthough.  This underscores a problem with this method of using a Metronome for putting.  Another approach for using a Metronome for putting is described in 3)
  3. This method has you take the putter back on the initial “tick” and strike the ball on the “tock”. You must change the setting on the Metronome from the one used in 1) or 2).  If your tempo is 90bpm using drill 1), set the Metronome to 60bpm for this method.  Why?  Because in drill 1), the time interval is based on a full “swing” (a full backswing and a full downswing).  In this drill, backswing to impact, the interval is based on 1 ½ “swings” (a full backswing and a half downswing).  So, in order to preserve the same tempo you must divide the setting for drill 1) by 1.5 to get the proper tempo for drill 3).  It is seemingly easier to follow this drill for putting over drill 2).  However, in this drill, there is no signal for the top of the backswing!
  4. Double time.  Set the Metronome to twice the setting in 1).  So, for 90bpm, the double time method would be set to 180bpm.  Now, start the putter back of the first “tick”, reach halfway back on the “tock”, arrive at the top of the backswing on the next “tick” and strike the ball on the next “tock” and reach your finish on the next “tick.  Needless to say, although this method provides an audio cue for all relevant parts of the stroke, it is almost impossible to follow!

Limitations of Metronomes

  1. Metronomes provide brief audio cues that mark the beginning or end of the main parts of a putting stroke but don’t provide feedback during the in-between parts of the stroke.
  2. Metronomes can only provide a swing ratio of 2.0.  Swing Ratio is the ratio of the backswing time divided by the downswing to impact time.  Data from hundreds of professional golfers has shown that the swing ratio is closer to 2.1.
  3. Method 3 provides a cue for the start of the backswing and impact but provides no cue for the top of the backswing.
  4. Method 2 is difficult to use because an impact cue, with impact being the most significant event in the putting stroke, is not provided for.
  5. Method 4 is extremely difficult to follow although it hits all of the significant positions as well as some you don’t need.

What is the answer to practicing putting tempo?

The solution is an easy to use Audio/Visual-based iPhone App that guides you throughout the putting stroke with continuous audio feedback as well as a visual guide of a perfect putting stroke that you can watch.

We call this training aid the “Puttronome” because it provides a guide to timing like a Metronome yet, is specifically designed to convey characteristics of a putting stroke.

In short, the Puttronome™ “sounds” like a putting stroke.  The Puttronome™ has emerged from years of research, analysis, and development.  The Puttronome™ is the result of a joint collaboration between Harold Swash Putting School of Excellence and DXP Tech LLC.

The Puttronome™ provides the following features

  • A simple user interface
  • Two modes of operation, “Pend” for the swinging drill and “Putt” for putting strokes
  • An audio tone whose pitch rises on the backswing and falls on the downswing with a distinct “impact” chirp that indicates when impact should occur guides you to a perfect putting stroke.
  • The audio sweeps from left to right on the backswing and from right to left on the downswing to give you additional feel for the  putting stroke (reversed for a left-handed setting).
  • The audio has a built-in Swing Ratio of 2.1.
  • Tempos include 72,78,82,86,90,95,100,100,106,113,120, and 129 bpm
  • A visual demonstration of a perfect accelerating putting stroke for short, medium, and long putting strokes as well as “swinging” mode performed by “Puttman” the putting demonstration Bot.
