The all-new INOVAI 8.0 was designed and engineered by Sam Bettinardi to instill maximum confidence and forgiveness while putting. The 8.0 was created with a 303 Stainless Steel front piece for a solid feel at impact, and a Military Grade 6061 Aluminum body that was designed with defined wings that offer more stability and higher M.O.I. numbers. The Armlock technique gives golfers more confidence on short putts and consistency on long putts by bracing the 17 grip along the left forearm. With minimal toe hang, one shaft of offset, and a 400 gram head, it is the perfect mallet for players with a straight-back, straight-through putting stroke, looking to try the PGA Tour proven method.
