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 in the SD-01 The Pro one and the SD-15 the country mile.

No issues

Arrived on time and without issue. I have not had a chance to use the golf balls yet, but I’m looking forward to same.

Great Ball

Did everything you would want , felt and sounded great

Great Ball with Great Feel

I hit the golf ball high and I do put quite a bit of spin on the ball so with a full shot, I can get these to stop wtih no problem. It is long off the tee and with the woods, iron length is would be expected. Short game shots have less spin, but then my short game is terrible. Putting is great and the "Jack" alignement is very good although as another reviewer has noted, sometimes the pattern is not square. Seed say that iy is a replacement for the AD333, I would say that it is a better ball than that. I'm more than happy to play this ball for the rest of the summer and it will be great in the winter, no doubt.

Goes a long way

Ball goes a long way and gives good control. They arrived on time with good delivery. My only niggle is the alignment arrow on 5 of the dozen is wonkey and definitely not square on the ball. It gives my playing partners opportunity to still laugh at my putting excuses.

Seed 15 The Jack

Can't rate the ball yet as I have not received it. The service from Seed is appalling.
