Description

The Odyssey TRTL Square 2 Square putter integrates a mid-sized mallet profile with zero-torque technology. Taking structural cues from the geometry of a turtle, this model is designed to restrict face rotation during the stroke while maintaining a high moment of inertia.
Shaft Integration and Zero Torque
The defining feature of this specific model is the shaft placement. By aligning the shaft with the clubhead's center of gravity and leaning it toward the target line, the design inherently resists twisting. This zero-torque setup is paired with a Stroke Lab 120 shaft, which is available in 33 and 34 inches. The intended effect is to promote a highly stable, linear putting stroke without requiring the player to actively manipulate the face angle.
Material and Weight Distribution
The stability of the clubhead relies on deliberate material placement. The central hexagonal section and the sole plate utilize lightweight materials to reduce mass in the middle of the club. The outer perimeter is constructed from heavier stainless steel. This effectively pushes the weight outward to restrict twisting on off-center strikes.
To further manage the center of gravity, this putter incorporates four interchangeable sole weights. The standard setup places two heavier weights in the rear and two lighter weights in the front, driving the center of gravity low and deep. Golfers can swap these weights to tune the putter for a shallower center of gravity or shift the bias toward the heel or toe depending on their natural stroke path.
Face and Insert Technology
Contact performance is handled by the Ai-STAR insert. This dual-layer construction features a resin striking surface backed by aluminum. The setup is designed to maintain consistent ball speed and forward roll even when contact occurs outside the exact center of the face. The Ai-STAR insert provides a slightly firmer feel and clearer auditory feedback at impact compared to earlier resin iterations. Because of the efficient energy transfer, the face design pairs well with a compact putting stroke.
Setup and Alignment Geometry
The physical geometry is carefully considered to help the player set up squarely to the target. The bottom of the putter features a flattened sole with minimal rounding. This helps the club sit flat and secure on the turf at address without naturally wanting to twist open.
For visual alignment, the club uses a Dual Track system. Two distinct, thick lines run from the face to the back of the head to…
