Odyssey Ai-Dual Square 2 Square Golf Putter | Max 1/2 Ball

The Odyssey Ai-DUAL Square 2 Square MAX ½ Ball is a centre-shafted mallet for golfers seeking a stable, square-to-square feel through the putting motion. Its defining feature is the ½ Ball alignment design: the putter’s visual frame helps centre the ball and gives the golfer a clear reference for aiming the face. The MAX head provides a generous mallet profile behind that alignment system.

Odyssey’s Ai-DUAL insert combines a soft urethane outer layer with a firmer inner layer, designed to maintain ball speed across the face and improve forward roll. A deeper FRD groove with a 19° slope works alongside the insert. The centre shaft sits below the centre-of-gravity plane, producing a toe-up balance intended to reduce face rotation and encourage the head to stay square through the stroke.

The Square 2 Square design includes 2° of built-in forward shaft lean and a reverse-taper grip intended to complement that hand position. The MAX ½ Ball standard model is specified with a black SL 120 stepless steel shaft. Its 365 g mallet head has 3° loft and a 72° lie, with 90° up toe balance. Standard lengths are 33, 34 and 35 inches; manufacturer specifications list right- and left-handed options. This is the standard-length version, distinct from the heavier, longer Cruiser build.

This configuration is a strong fit for players who prefer a centred shaft, a toe-up balance and pronounced alignment help. Use the half-ball graphic to settle aim, then make a smooth stroke with the face square to the intended start line. Verify hand, length and grip availability on the retailer page before ordering; included headcover.

The Bold Golfer FAQs

Got questions? We’ve got answers! If you do not find your answer here, please use the contact page to let us know.

What makes The Bold Golfer different from a traditional online pro shop?

Unlike standard retail outlets, we do not stock physical inventory, manage transactions, or ship orders. We operate as an independent golf publication and globally aggregated product catalog, sourcing real-time deals from trusted manufacturers and merchants worldwide to simplify your golfing gear research.

How do your country-specific live pricing buttons work?

We partner with premium golf merchants across different continents. When browsing a product, simply click the button matching your region (e.g., USA, UK, AUS, or EU) to be directed instantly to an authorised local retailer with current stock and localised pricing.

Do I pay any extra fees or hidden premiums by using your outbound links?

No. Every outbound link on our site redirects you directly to the official merchant's checkout at zero extra cost to you. Our platform is fully supported through tracking commissions paid to us by our retail partners when you complete a qualifying purchase.

Who should I contact if I have an issue with an order or a delivery delay?

Because all sales are finalised directly on our partner merchants' secure websites, any questions regarding order processing, shipping, tracking numbers, or returns should be handled directly with the specific retailer you purchased from.

Are the products featured on your site brand new or pre-owned?

Our automated product feeds primarily highlight brand-new, current-generation golf equipment from major manufacturers. However, when we link to specialised premium clearance warehouses, any pre-owned or refurbished status will be clearly indicated on the partner site.

How do you choose which golf brands and products to feature on your website?

We select brands based entirely on manufacturing compliance, tournament-tested reputation, and user feedback. From industry titans like TaylorMade and Callaway to elite direct-to-consumer simulator labels, we aim to cover the full spectrum of high-performance gear.

How often is the product data and retail stock updated?

We utilise dynamic product data feeds that sync regularly with our global affiliate networks to ensure that our configurations, manufacturer names, and global retail channels remain accurate for our community of golfers.
