Putting is pretty simple. Figure out the right spot to aim and you’ll make more putts.


So how do you do that? Glad you asked.


Our Green Cards are like the Ultimate Putting Cheat-Sheet. They’ll tell you exactly where to aim for every putt based on the slope and green speed - built with Tour-Proven Data and meticulously tested for accuracy and reliability by top PGA professionals. They even come with a Stimpmeter.


Since our Green Cards rely on slope percentage for accuracy, you might also want to use them alongside our Slope Plate green-reading training tool. We mention it because using them together has led to even better real world results, not because we’re trying to upsell you. Promise.

WHAT'S INCLUDED

- Green Cards

- Portable Stimp Meter
- Carrying Case

- Custom Training Videos w/ In-Depth Instruction
- Exceptional Customer Support
- 99 Day Money Back Guarantee - Not happy? Send it back for a full refund

Putting Thing - Excellent Training Aid

Excellent tool

The putting thing works. I hit the sides a lot at first, but now my putting stroke is getting straighter and more square in only a few days with a few minutes per day

Solved my biggest issue

Getting that ball started on its intended line and toe strikes were my two biggest problems. The Putting Thing has given me the confidence to go into this golf season knowing my putting is where I want it to be.

Doug Knight
Most advanced putting trainer

The gates are the neastest part. They're attached to the unit so they don't fall off and you won't lose them and they're adjustable. Thanks WhyGolf!

Hi Doug, thank you for your positive feedback on our Putting Thing! We're happy to hear that you find the gates to be a useful and secure feature. We appreciate your support and hope you continue to enjoy using our product! -WhyGolf Team

Single best training aid

This is the single best training aid I have purchased in a long time. It is simple to set up and use and feedback is instantaneous and unambiguous. I pair it up with my phone videoing my stroke and the faults become easy to see.

Hi there! Thank you so much for your review. We are thrilled to hear that our Putting Thing has been a valuable training aid for you. We designed it to be user-friendly and provide instant feedback, so we're glad to know that it's working well for you! -WhyGolf Team
