A quick, accurate, and LEGAL way to determine the slope of the green!

  • If you hold your putter like a pendulum, on a flat surface it will hang straight down.

  • When the green is sloped, the putter head will swing to the downhill side

Slopey the Robot shows you how SlopeVision works!

The angle formed at the grip is the SAME as the angle of the green!
The putter will move an EXACT distance for each % slope
SlopeVision marks those distances so you can read the slope from your putter head!

  • STEP 1

    Along the line of your putter find a natural mark on the green, for example, a blade of grass or piece of sand. Place your feet so that the natural mark is EXACTLY between your feet.

  • STEP 2

    Standing straight and perpendicular to the green. Lift the putter head slightly above the surface and directly in line with the center of your body (plumb bob).

  • STEP 3

    If there is a slope, the putter will move and a SlopeVision mark will align with the mark between your feet. Read the slope directly from your putter!

See how it works on a real green!

  • Step 1

    On a level floor, pick a mark that is exactly in the middle of your stance. (A line formed by flooring works well.)

  • Step 2

    Stand straight holding the putter lightly in your fingers in the middle of your body about 1 inch below the end of the grip. Look down through your grip point to where the putter lines up with the line on the floor.

  • Step 3

    Mark that spot with a marker. This is your 0% slope mark.

  • Step 4

    Choose the SlopeVision template that matches your putter length. Proceed to mark your putter for each % slope.

Teaching Professional Review

I have found SlopeVision is a great way to quickly get a very accurate slope on the green. Also, it is much easier to teach and my students learn it more quickly than other methods of determining slope.

Why use SlopeVision?

SlopeVision is easy to learn and can be much more accurate than using your feet or eyes alone.
It is easier and more reliable under pressure or in conditions where ‘feeling’ the slope can be difficult.
Once you have an accurate % slope number, you can use other means to determine your starting line like using your fingers or a formula.

Does it conform with the Rules of Golf?

Yes! Equipment Rules allow for decorations or lines that are “permanent or semi-permanent”. Using a marker is considered semi-permanent.
Playing Rules state “a player may use their club as a plumb line to assist in judging or gauging slope”
