BUILD MORE CONSISTENCY, MAKE MORE PUTTS





Let customers speak for us
from 24 reviewsGreat tool for putting the ball exactly straight the first time and thereafter. Highly recommended.
Just started practicing with it! Looking good! I’ve already made several adjustments resulting from its use!!!! Thanks for getting together with Mister One Putt!
Can’t make it to golf course or range because of right arm & shoulder injuries but using one putt ruler at home. It’s terrific! Showed me that I’m pulling to the right & not square at contact
I’m starting more putts on my line
Just started using it, indoors, but it has helped me to get the putter head back straight and thru straight with a better chance of making more putts.
A phenomenal training tool! It gets you rolling the ball down your intended line and it’s also helping with speed and distance. Get yourself one of these, you won’t be disappointed.
The One Putt Ruler gives me instant feedback on the putt's start line and helps train the path of the putter in the forward stroke. I like that it is built of sturdy metal so it will last for years, and it holds its alignment on the floor or putting green due to its weight.
My playing partners always said I come across outside in and cut the ball. I never thought I did but they could see it I couldn't. Now with "the ruler" I see it feel it and now corrected. Hopefully after 2 weeks it will translate to the course I expect it will.
I work on my putting with a desire to get better. The One Putt Ruler is built well and works! I was amazed at how quickly I got used to it. I now use it as part of my practice routine every time.
I have already started getting a better end one and roll, not as much wobble. The only strange thing is it makes a quiet noise every time I gut the ball, like the ruler is bowed. Even though I don’t think it is.
Mr.one putt has nailed it
This is the most convenient and durable start-line training aid available. The all-metal construction prevents warping in the sun or hot car trunk. It easily fits in a golf bag pocket. The backstroke markings are a great reference for those short putts of five to eight feet and allow you to check the squareness of the putter face. The One Putt Ruler is non-reflective and unobtrusive on the practice green. It can be used outdoors or indoors on any putting mat. The One Putt Ruler is a great value given its durability and usefulness.
Great tool!
Very good to keep you online for the first nine inches. Used it on the practice green and when you keep the ball on the line it rolls true every time.
Well made and easy to use.
