Why pay for forgiveness when you can own consistency?
Start hitting more putts out the middle with the world's simplest putting training aid, the Middler.
Putting is all about feel, but there is no feel without consistency. The Middler putting training aid helps you develop an easy to repeat putting stroke that is consistently on plane and square at impact.
The Middler is available in two sizes: the elite M5 for handicaps below 5, and the M7 for everyone above.

Bead-blasted lightweight aluminium


Bead-blasted steel
Fully compliant with R&A / USGA rules regarding ballmarkers and alignment devices.
Line up the
Looker
The ballmarker that doubles as an putting training aid. Pick your target, align your putter, hole your putt.
The Looker alignment system helps you pick a target on the green, trace it back to your ball, and then align your ball and putter so you are set up bang on target.
There are many reasons why we miss putts. Not aiming where we think we’re aiming no longer needs to be one of them.

About us
Founders Alan Emmins and Aaron Bateman are two English golfers (one decent, the other decent on his day) who live and work in Copenhagen.
Friends for more than 15 years, they started Three-20 when Alan remembered a putting training aid his grandfather had made for him decades ago.
After the first prototypes confirmed the Middler’s potential to help you groove a more consistent stroke, they went into production in August 2023.
Three-20 is born from the idea that while we might not all be able to swing like a pro, we believe you can putt like one.
