Odyssey Ai-DUAL Seven (#7) 1/2 Ball S Putter — Steel + Headcover

The Odyssey Ai-DUAL #7 1/2 Ball S is a stable mallet putter in the iconic #7 shape, built around easy alignment and a confident ball start. It combines the distinctive 1/2 Ball alignment aid — which frames the ball at address — with a Short Slant (S) hosel that adds toe hang, making this putter an excellent fit for golfers who putt on an arc with greater face rotation through the stroke.

Key Features

• 1/2 Ball Alignment — frames the ball at address for easier, more precise setup and centred contact.
• #7 Mallet Shape — long-trusted head shape offering high stability and forgiving off-centre putts.
• Ai-DUAL Insert (dual-layer) — AI-designed soft urethane outer layer over a firm inner core for consistent ball speed and better roll.

• Short Slant (S) Hosel — 35° toe hang suits arc stroke players who prefer a naturally releasing, closing face.
• SL 90 Steel Shaft — lightweight steel shaft with approx. 20 g counterweight at the grip end for consistent tempo and stroke repeatability.
• Includes Headcover — putter ships with a matching headcover for protection on and off the course.

Technology in Detail

Ai-DUAL Insert

This dual-layer insert, developed with the help of artificial intelligence, features a soft urethane outer layer bonded to a firm inner layer. The combination delivers consistent ball speed across the entire face — even on off-centre strikes — while also promoting improved forward roll from the moment of impact. The result is a putter that feels exceptionally soft at address yet provides the feedback and responsiveness serious golfers demand.

New FRD Grooves

The redesigned Forward Roll Design grooves are deeper and more aggressive than before, angled at 19° across the face. Working in concert with the dual-layer insert construction, these grooves help the ball transition quickly and smoothly into a stable, end-over-end forward roll — both high and low on the face. The faster the ball gets rolling true, the more predictable the pace and line become.

SL 90 Shaft

The Odyssey SL 90 is a lightweight steel shaft fitted with approximately 20 grams of counterbalance weight positioned at the end of the grip. This counterbalancing configuration shifts the balance point higher in the putter, promoting a smoother, more pendulum-like stroke. Odyssey's own testing consistently shows that players achieve greater stroke consistency and better tempo with this setup compared to traditionally balanced shafts.

Odyssey Pistol Grip

The Odyssey Ai-Dual Pistol grip is a midsize pistol-shaped grip with a proven size and profile that suits a wide range of golfers. Its familiar taper and shape encourage a neutral hand position and light grip pressure — both key ingredients for a repeatable, tension-free putting stroke. The grip is fitted as standard across most length variants, with a Slim Pistol option available on the 32-inch variant.
