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.

Included with Purchase:

  • Portable Stimpmeter for measuring green speed
  • Carrying case
  • Custom Training Videos w/ In-Depth Instruction
  • 99 Day Money-Back Guarantee - Not happy? Send it back for a full refund.

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

Reducing 3 Putts

This a great training aid. I use it for weekly practice on my putting. I have had it for just over a month and seen a real decline in 3 putts which have been killing my game. I have seen a 1.8 stroke improvement in putting since using the Putting Thing. I would highly recommend getting one and using it with your Putting practice.

A lot of my students struggle with aiming their putts. The Putting Thing has all the tools you need to become a great putter. One of my favorites!

Getting FAST Results

SUPER easy to use. The Putting Thing's adjustable gates make me want to practice putting. I use it for a couple minutes before I go play and it's paying dividends. Highly recommend.

I absolutely love it

absolutely love it. 3 session so far. Dialed to a 4. Has made a big difference already. Especially on the final hole that required a 6 ft putt to win the round

Green Cards FAQ's

How do the Green Cards work?

Green Cards are designed to be used on the golf course as you play. In a matter of seconds, you'll know exactly how much your putt will break.

Pair Green Cards with our Slope Plate for an unbeatable combination that trains you to read slopes with your feet accurately.

Why did we create the Green Cards?

We created the Green Cards to provide golfers with a definitive edge in precision putting. Recognizing that most golfers lack the time for extensive green-reading practice, our cards streamline the process, enabling accurate putt alignment based on specific green slopes and speeds.

Is the data on the Cards based on the assumption that putts will travel a specific distance past the hole?

Yes. Each data point assumes that the golfer will hit their putts 18" past the hole.

Are the Green Cards USGA legal?

The Green Cards are permitted under the USGA Rules of Golf.

How will I know what card to use?

Your purchase includes a handy Stimpmeter, allowing you to measure the speed of the greens you play on. Once you know speed of the greens, pick the corresponding Green Card and you're ready to go.

How do I know what % slope my putt is?

Many golfers practice with a level on the putting green to train their feet to consistently detect the break percentage. However, time constraints prevent most from regularly engaging in this practice.

Our Slope Plate makes it easy for you to learn how to feel the break from the comfort of home. In case you are interested, here's a link.

What do the numbers in RED on the Cards mean?

Red numbers indicate that you should aim towards the center of the cup, not away from it. For instance, '1/2 B in' in red means you should aim half a ball's width inside the cup's edge.

How do I use the Stimpmeter?

The included Stimpmeter operates identically to the Putting Thing's, ensuring you can measure the speed of greens with precision and consistency. Click here to watch the Stimpmeter video.
