For years, Odyssey has been one of the most influential Putter brands in golf—and with the Tri-Hot Square2Square series, Odyssey brings the concept of Zero Torque (ZT) to life in a particularly consistent, tour-inspired design. The goal: greater stability at impact, less unwanted twisting of the putter head, and thus more consistent direction and speed—even when the ball isn’t struck perfectly in the center.
If you’re a golfer who wants to gain a basic understanding of Zero Torque technology (torque, MOI/moment of inertia, perimeter weighting, and forgiveness), we recommend reading our guide first: “Zero Torque: Putter Technology Explained Simply.” This article focuses specifically on the Odyssey models —and on which setup might be right for you.
Odyssey positions the Tri-Hot Square2Square putters as a modern interpretation of the Zero-Torque concept: The design is engineered so that the Putter remains as stable as possible at the moment of impact and is less affected by off-center hits.
Key features you’ll find across all models:
In short: Odyssey combines a mix of materials, center-of-gravity design, and Square2Square geometry to translate the ZT principle into a setup that many players find “automatic” and “reassuring.”
To help you quickly identify the key features, here are the technologies that Odyssey particularly emphasizes in the Square2Square models:
Odyssey relies on an AI-developed dual-layer urethane insert (soft outer layer, firm core). The goal is more consistent ball speed across the face and improved roll.
According to the description, the FRD Groove is a deep, aggressive groove with a 19° angle designed to promote forward spin and ensure a clean ball launch.
With aluminum, steel, and more than 140 g of tungsten, weight is strategically placed where it contributes most to stability and forgiveness.
All four putters are priced at 499.99 euros as listed in the descriptions. Differences lie primarily in head shape, loft, shaft/grip setup, and—in the case of the Cruiser—additionally in length and weight.
The Seven is a high-end model for golfers who want a highly controlled setup but also place great value on a soft sound and feel at impact.
What sets it apart
Who is it for? If you’re a golfer looking for a “premium standard” in the ZT world—stable, tour-inspired, and with a very deliberate focus on sound and feel.
The Jailbird is designed as a Mallet in the Square2Square configuration and also features a distinctive vortex-style design, which, according to the description, is intended to promote stable performance even in windy conditions.
What sets it apart
Who is it for?If you’re a golfer who prefers a tour-style Mallet setup with precise grip control and want a model that Odyssey specifically highlights for its stability in windy conditions.
The Rossie appeals to golfers who want the benefits of ZT but prefer a more compact Mallet design in their hands.
What sets it apart
Who is it for? If you’re a golfer looking for a slightly more compact head feel but still want to take advantage of the full Square2Square/Zero-Torque characteristics with stable, controlled Performance.
The Jailbird Cruiser brings the Square2Square concept to a deliberately stability-oriented “Cruiser” setup. Here, you get not just a Mallet head, but a setup that provides added reassurance through greater length, more weight, and a significantly longer grip.
What sets it apart
Who is it for? If you’re a golfer looking for a deliberately calmer, heavier, and longer putting setup—and you feel particularly comfortable with the “Cruiser” concept (longer shaft, long Grips).
| Model | Head Shape | Loft | Length | Weight | Shaft | Grips | Special Feature |
|---|---|---|---|---|---|---|---|
| Seven | Square2Square Seven | 3.5° | 33"–35" | 365 g | Custom Graphite (counterbalanced) | Full Contact Slim | SCS + Chain Link Milling, designated RH/LH |
| Jailbird | Jailbird Mallet | 3° | 33"–35" | 365 g | Black SL 120 | Pistol Plus | Vortex design (wind-stable) |
| Rossie | Rossie Mallet (compact) | 3° | 33"–35" | 365 g | Black SL 120 | Pistol Plus | More compact Mallet design |
| Jailbird Cruiser | Jailbird Cruiser Mallet | 3° | 38" | 385 g | SL140 | Pistol Plus 17" | Longer, heavier cruiser setup |
To help you, as a golfer, find your way more quickly, here’s a simple guide:
Tip: Especially with Zero-Torque setups, it’s worth paying attention to length, lie, grip feel, and your setup routine. If you’re unsure, it’s best to seek advice or test several options to find the model that gives you the most confidence over the ball.
With the Odyssey Tri-Hot Square2Square ZT putters, you get a consistent zero-torque design that features a forward center of gravity (CG), topline hosel, multi-material construction with tungsten, and modern insert technologies. The four models cater to different preferences—from a feel-focused premium all-rounder to a stability-oriented cruiser setup.
If you’re a golfer looking to stabilize your line and achieve more consistency in your roll, the Square2Square models are definitely worth a look (and ideally a test on the range).
