Callaway Golf Japan rolls out the “fifth iconic mallet” in the new Odyssey TRTL (Turtle) putter range.
In the alternate world of golf equipment coming out from Japan, Odyssey released the new range of TRTL (Turtle) putters that the company professes is its fifth mallet design. Released in August nationwide in Japan, the TRTL is a next-generation, high moment of inertia (MOI) putter that is meant to sit alongside other iconic models like the Rossie, #7, Jailbird and 2-Ball in Odyssey’s history.
The design of the club reflects its unusual name. Look underside and the hexagonal, turtle-shell-shaped body is at the centre of the sole, the four extensions mimicking a turtle’s legs. The green head cover, shaft decal and grip band with a deep forest-green colourway further extends this motif.
High MOI putters are better suited to slower, more deliberate strokes. This goes hand in hand with the putter’s characterization and how it needs to be swung.
The Odyssey TRTL putters introduces the brand’s first four-weight sole system.
There are four adjustable sole weights, positioned at the four corners of the hexagonal body. The flagship DB model has the standard configuration of two 10g weights in the front and two15g weights in the rear, biasing the centre of gravity (CG) deep for maximum MOI. Weights can be swapped to further fine-tune the putter for personal preferences.
Odyssey introduces a brand-new face insert in the Ai-STAR, a two- layer construction that incorporates a urethane striking layer bonded to an aluminum back. While a similar design is found in the original Ai-ONE, the TRTL is tuned firmer, with a higher, crisper impact sound and a noticeable boost in ball-speed efficiency (Impact Ratio).
The aiming aid has also been tweaked. Two parallel sightlines now extend from the face to the rear of the putter head. The slightly rounded topline, and a low-curvature sole prioritizes squaring the face at address rather than framing the ball visually – a fundamental departure of philosophy from the 2-Ball.
Golfers who shy away from overly chunky putters will be happy to note that the TRTL has a mid-sized head, with the lightweight central body allowing perimeter weighting to help with the high MOI feature.
The Odyssey TRTL comes in several models to suit different tastes and putting styles. The TRTL DB are for those who prefer a straight-back-straight- through strokes, and a face-balanced feel. TRTL CH has a crank hosel with a bit more toe hang and draw bias, which helps players who fight a push and want more feel through the stroke.
TRTL S has a hosel with a short slant, and more toe hang, aimed at those with a more pronounced arc in their strokes. And if you’re in the market for a zero torque putter, the TRTL Square 2 Square is the one to consider with its forward CG, and heavier shaft.
The S2S TRTL uses a heavier STROKE LAB 120g shaft and a lighter Reverse Taper 2.0 TRTL SLIM grip (48g), with weighting shifted forward to eliminate face rotation through the stroke.
