Explanar

The golf swing is one of the most complex bio-mechanical movement performed in any sport and most people are only ever taught verbally.
Now you can learn by feeling not thinking using the Explanar – a mechanical aid like training wheels on a bicycle, providing support and feedback that you can feel.
Golf coaches find it easier to teach this complex movement with an Explanar, improving the way students learn and play and it is used by many of the World’s top golf professionals and coaches.
