Odyssey Ai-One Square 2 Square Double Wide Putter Review

Quick Summary: Is the Ai-One Square 2 Square Double Wide Worth It?

The Odyssey Ai One Square 2 Square Double Wide is built for golfers with a straight-back-straight-through putting stroke who want the putter face to stay square without conscious effort. At $349, it positions itself as an accessible entry point into zero torque technology—considerably more affordable than lab putters like the Mezz 1 Max or PXG Battle Ready II Allan.

What stood out in testing:

• Exceptional stability for a blade putter through the stroke—the face genuinely resists twisting even on off-center contact
• The ai one insert delivers soft, consistent feel with minimal ball speed variation from heel to toe
• High MOI from the double wide head forgives mishits that would punish traditional blades
• Alignment feels almost automatic thanks to the center shaft and square profile

The main caveat: This putter demands commitment to a fairly straight stroke. If you naturally swing with a strong arc, the toe-up balance will feel restrictive rather than liberating. Wondering if it fits your game? Read on.

Design & Technology Overview

Behind the ball, the Odyssey Ai One Square 2 Square Double Wide looks modern but not alien. The navy blue PVD finish on the cavity pairs with a blue ai one window that reveals the insert’s contours underneath. It’s wider than a traditional blade, obviously, but the profile sits lower than you’d expect—less mallet, more oversized blade.

The “Square 2 Square” name describes the core philosophy: this putter is engineered to stay square from setup through impact. The center shaft positions directly above the cg plane, creating a natural toe-up orientation that virtually eliminates torque. You set it down, and the face sits square to your right line without any manual adjust needed.

At the heart of performance sits the AI-designed white hot urethane insert. Odyssey used data from thousands of strokes to map an aluminum backer with variable thickness behind that classic soft urethane layer. The result? Consistent ball speeds whether you catch it pure or drift toward the toe. A 19-degree groove slope promotes forward roll from initial contact, reducing skidding on short putts.

The forgiving head weighs approximately 365-370 grams, with tungsten concentrated low and in the heel-toe for maximum stability. Stock specs include lengths from 33 to 35 inches, a Stroke Lab center shaft, and an oversized pistol-style grip. That grip contributes 20-30 grams of counterbalance weight that makes the swing feel lighter despite the substantial head.

Build quality impressed throughout testing. The PVD coating resisted wear, and the 3.3-degree forward shaft lean promotes a hands-ahead forward press position at address without requiring conscious manipulation.

On-Course Performance & Feel

Testing spanned multiple rounds on medium-fast greens, including one particularly memorable session at Bonita Bay East where wind added an extra layer of difficulty. The conditions revealed exactly what this putter does well—and where expectations need calibrating.

Start-line accuracy is where the Ai One Double Wide earns its keep. On nervy 4-8 footers—the range where most amateurs leak strokes—the stroke balanced design kept the face rock-solid. There was no twisting or wobbling through impact, even when adrenaline crept in. Putts started on the intended line consistently, which built genuine confidence over the ball.

Distance control proved equally impressive. The ai one insert’s claim of smoothing out ball speed variation held up in practice. Mishits off the toe or heel didn’t bleed as much speed as they would with a traditional blade. Lag putts over 30 feet rolled out predictably, making two-putt territory larger and more reliable.

The feel deserves its own mention. Impact produces that classic soft, slightly muted sensation that the old White Hot was known for—not harsh, not dead. There’s enough auditory feedback (a crisp “thwack”) to distinguish pure strikes from slight misses, which helps the feedback loop when walking between holes.

Alignment confidence surged thanks to the center shaft and square topline framing the ball symmetrically. That said, expect an adjustment period. Coming from toe hang blades or face-balanced mallets, the toe-up lean initially feels unconventional. It took about three practice sessions before setup felt natural rather than forced.

On green speed adaptability: the stock head weight suited faster surfaces where stability shines. Slower greens might benefit from lead tape or aftermarket weight adjustments, though no major inconsistencies appeared across varied conditions.

Who Should Play the Ai-One Double Wide?

This putter targets a specific golfer: someone with a minimal-arc or straight putting stroke who fights pushed or pulled putts due to inconsistent face alignment.

Who benefits most:

• Mid-to-high handicappers seeking forgiveness and simplicity without graduating to oversized mallets
• Golfers frustrated by punishing blades who want stability without sacrificing a blade-like profile
• Better players wanting “point-and-shoot” reliability on fast, tricky greens

Who may struggle:

• Strong-arc stroke players who rely on natural face rotation feedback
• Golfers uncomfortable with center-shafted, symmetrical square aesthetics
• Anyone deeply attached to plumber’s neck or offset hosel designs

Fitting matters here. Check lie angle, length (shorter 33” for compact builds, longer 35” for taller postures), and grip sizing. The added benefit of proper fitting is ensuring the stroke plane matches the putter’s zero torque design.

Comparison: Ai-One Square 2 Square vs Other Zero-Torque & Odyssey Putters

The recent putter market has seen zero torque putters proliferate rapidly, giving golfers real choices at various price points.

Versus LAB DF3: Both deliver comparable stroke balanced stability and face-rotation control. The Odyssey offers a softer feel from its Ai One insert and wider availability for fittings, but less extreme customization in shafts or weighting. LAB commands a premium; Odyssey matches Ai-One family pricing without a “tech tax.”

Versus LAB DF 2.1: The most forgiving putter that I have ever tested. It is very large and requires an adjustment period. For golfers who prefer that classic Odyssey feedback, the Ai One Double Wide wins on feel alone.

Versus LAB Oz: Similar reduced rotation philosophy, but Odyssey’s AI-enhanced speed consistency and brand familiarity give it an edge for mainstream players.

Versus Scotty Cameron Phantom 11R OC: It is hard to beat Scotty Cameron putters, but the Ai One Double Wide wins on price. The Scotty Cameron is Expensive.

Within Odyssey’s lineup: This differs from the Ai-One mallets like the Square 2 Square Jailbird by emphasizing extreme toe-up squareness over typical face-balanced MOI. 

The difference for most golfers comes down to feel preference and budget. Callaway’s AI lab backing ensures the technology is proven; the rest is personal fit.

Pros, Cons & Final Verdict

Final Verdict: The Odyssey Ai-One Square 2 Square Double Wide delivers on its promise. For golfers whose game suffers from inconsistent face alignment—especially those with naturally straight strokes—this putter offers life-changing stability at a reasonable price. It won’t suit everyone, but for the right stroke profile, it’s one of the most accessible ways to experience what zero torque technology can do for your putting. If that sounds like your bag, get fitted and give it a serious test.
