You've probably all seen those miniature sized holes on putting greens somewhere .
The issue with these is that only the perfect lag putt would drop in and this promotes a weak putt, not a strong one.
There were also gadgets that reduced the entrance to the hole, but only by adding a block at the back.
So we set out to develop something that reduced the entrance, without blocking the exit. During design, this led to the perfectly balanced design of a 5, 6, 7 and 8cm entrances to the hole.
Couple this with the simple way the tool can help visualise the entrance to the hole on turning putts and you have a super lightweight and simple Training Aid that cannot fail to improve your putting performance.
