Helps keep you straight.

The Jack is Seed's take on an alignment device, designed to help improve your putting accuracy, alignment and stroke.

The two large side circles create a strong visual alignment aid, allowing you to more easily line the ball to the hole.

The circle device also provides an instant diagnostic tool for the putting stroke, swing path and strike.

A balanced and centred stroke will result in the ball rolling true and straight, with the circles creating a visual affirmation (straight, clean roll). An open or closed putter face, an overly inside or across the line stroke will all cause the circles to “wobble” after impact, indicating a less than perfect strike.

The off-centre roll provides immediate visual feedback regarding the stroke and path. If stroke is an issue, the golfer also can turn the ball 90° and visually see the skid, spin and roll characteristics of the ball from their stroke.

This can be very useful for teaching professionals or anyone who is videoing the putting action looking for more visual feedback.

In research conducted by Seed, 86% of golfers found improved results on 6ft putts by using The Jack over traditional single line alignment device.

The Jack alignment device is available on the SD-01 The Pro golf ball, White only.

Very poor quality…..’hollow’ sound when struck. Sounds like a ‘dud’ ball. Would not purchase again.
