SlopeVision’s Templates allow you to see the exact % SLOPE of the green based on how your putter moves while plumb-bobbing. Permitted by the Equipment Rules and patent-pending, this simple tool allows you to gauge the slope of any green. Why It Works Physics: Your putter, when held like a pendulum, moves an EXACT distance downhill for every % Slope. As long as gravity works, this technique will work perfectly every time. Easy to Use: Learn the simple setup technique and you will become deadly accurate estimating the slope. It's so much easier than "feeling" the slope. Quick to Perform: Within a couple seconds you can read the slope of the green directly from your putter. Universal Fit: Works with any putter design. How to Use SlopeVision Templates Find zero: On a level surface, find a point on your putter head that aligns with a spot that is directly between your feet. Mark that point on your putter head. Mark Your Putter: Grab the Template that matches your putter length. 29” to 42” are included (contact us for different lengths). Now align the 0% mark on the Template with the alignment mark you made on your putter and make the remainder of % slope marks according to the Template. Use Your Putter as a Plumb Line: Hold your putter in the middle of your body about 1 inch below the grip end. Read the Slope: Pick a spot on the green in the middle of your stance and see which alignment line on your putter aligns with that spot.
