The Slope Revealer

*30-day money back guarantee

Tired of guessing every putt, and leaving strokes on the green?

Let's be honest. Eyeballing slope is unreliable.  Practicing the feel of the slope can help, but it doesn't give you the exact number.  And those clunky hardware-store levels? They force you to bend down, break your putting rhythm.


While you're relying on outdated methods, PGA Tour pros and savvy amateurs are dialing in every putt with scientific precision. They know the exact slope percentage before they even address the ball. Ignoring this is costing you strokes and confidence.

Frequently Asked Questions

What exactly does the Slope Revealer Pro do?

The Slope Revealer 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.

The NINES GOLF™ 30 day Stress Free Guarantee


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 Slope Revealer Pro difficult to use?

Not at all! The Slope Revealer 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 Slope Revealer Pro and the Birdie Bubble Classic?

The Slope Revealer 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 Slope Revealer Pro allowed in tournaments?

The Slope Revealer 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.

Do the Stimp Sticks work on all types of greens?

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