The Green Machine is the lightest putter in the Bumpjump range.(Head weight 310g/10.9oz)

As with all Bumpjump putters it has a raised striking-face, which means you're always striking the middle of the ball with the centre of the putter face.

The heightened face puts a natural top-spin on the golf ball as the club head moves forward through the putt.

The polymer insert gives an unsurpassed smooth contact and delivery.

Another feature about the Green Machine is it's unusually long face. This gives the golfer the added confidence of hitting the ball sure and true.

The Green Machine is fitted with a top-spec pistol grip, which fills the palm of the hand and also leaves plenty of thumb room.

Golfers already using this remarkable club report back that they are saving two and more shots per round.
