Mastering the Speed 💨

PGA pros rely on the “stimp” rating to measure green speed. But conventional stimpmeters can be bulky and tough to carry on the course. That’s where we come in. 


The Stimp Sticks are Lightweight, Easy to Use, Alignment Sticks that are designed with a snap-in stimp attachment for Seamless Speed Measurement—giving you a direct stimp rating (e.g., Stimp 9) with ease.

Clip in Stimp attachment

Simply roll a ball, measure the distance, and you’re set. Learn How to Use a Stimp Rating for in-depth instructions.

Don't want to get the measuring tape out? 📐

Use our very own Quickstimp Feature 👇
Want fast, straightforward stimp readings? No measuring tape required. The Stimp Sticks' Quickstimp feature is a game-changer. Set the attachment to "Quickstimp," and the sticks will show you the precise stimp rating, hassle-free. Read more on Quickstimp and How It Works.

Frequently Asked Questions

What exactly does the Birdie Bubble Pro do?

The Birdie Bubble Pro measures the slope percentage of the green to help you read putts accurately. By knowing the slope, you can gauge how much the ball will break on the green, helping you make precise putts without guessing.

How does a stimp measurement improve my putting game?

The stimp rating measures the green speed, which is key to understanding how far the ball will roll after putting. Knowing this helps you adjust the force of your putt according to green speed, so you can better control distance.

We offer a risk-free option because we believe in the product so much.  It means that after a full 30 days if you are not completely convinced by the amazing results then just get your money back.

Is the Birdie Bubble Pro difficult to use?

Not at all! The Birdie Bubble Pro is designed for simplicity, showing instant and accurate slope readings. With a quick glance, you can see the slope percentage and adjust your putt accordingly.

How do I use the Stimp Sticks to measure green speed?

The Stimp Sticks come with an easy snap-in attachment. Just roll a ball on the green using the sticks, measure the distance it travels, and you’ll get an accurate stimp rating for green speed.

What is Quickstimp, and how does it work?

Quickstimp is a fast and simple feature on the Stimp Sticks that gives you an instant stimp reading without the need for a measuring tape. Just set the sticks to “Quickstimp,” and you’ll get the green speed in seconds.

Do I need both the Birdie Bubble Pro and Birdie Bubble Classic?

The Birdie Bubble Pro provides professional-grade slope readings, while the Birdie Bubble Classic offers an accessible, compact option for general slope reading. Together, they cover all your needs, but if you’re just starting, the Classic may be enough.

Is the Birdie Bubble Pro allowed in tournaments?

The Birdie Bubble Pro is designed as a training tool to help you develop your green-reading skills and gain confidence in practice. It provides accurate slope data, which helps you learn how to assess breaks more effectively. However, like most green-reading aids, it’s not intended for use in official tournament play, where equipment rules apply. We recommend using it during practice rounds or on the practice green to refine your skills before stepping into competition.

What’s included in the Complete Calibration Bundle?

The Complete Calibration Bundle includes the Birdie Bubble Pro, Stimp Sticks with Quickstimp, and the Birdie Bubble Classic. Plus, you’ll receive two bonuses: the Speed and Slope Playbook ebook and Magnetic Grip Tops to enhance your putting alignment.

Yes, the Stimp Sticks are versatile and designed to work on various green types and speeds, helping you adapt your putts across different courses.
