Yes Square Triangle Esoteric Golf

The Square Triangle is a product that everybody can bring, everywhere. It is small, only weighs a few grams and is extremely efficient on the practise green as well as on the putting mat. You aim the putter towards a hole and then place the Square Triangle in front of the putter blade. By placing yourself behind the Square Triangle, and reading the line, you can easily see where you were really aiming. Then adjust the Square Triangle straight towards the whole, place a ball – and make the putt!
