Odyssey TRTL Putter Review: the High-MOI Turtle Arrives
Odyssey's new TRTL mallets, the "Turtle", bring a four-weight adjustable sole and a fresh Ai-STAR insert, with early reviews among the best of the year. Here's the range, the tech, the price and who it's for.
Odyssey has a new high-MOI mallet range, and it's the most interesting putter launch of the year. It's called the TRTL, nicknamed the Turtle, and after quietly landing in Japan in August it hits the US on 6 November 2026, with the UK and the rest to follow. The headline is a sole you can actually tune, and early reviews have been unusually strong.
The range: four models
There are four TRTL putters. Three are mid-mallets with two alignment lines, the S, the DB and the CH, so you can pick the head shape and alignment look you prefer. The fourth is the Max, a larger zero-torque design Odyssey calls Square 2 Square, built to keep the face square through the stroke. US pricing is $349.99 for the S, DB and CH, and $399.99 for the Max. UK and EU pricing has not been announced yet.
The headline: a four-weight adjustable sole
The thing that sets the TRTL apart is the sole. It carries four weights, one in each corner, which Odyssey says is its first four-weight sole system. Because they sit in the corners, you can shift the centre of gravity front to back and heel to toe, so you can tune the putter to your stroke rather than buy a fixed one. That is a genuinely new idea in a mallet at this price.
The insert and the build
The face is a new two-layer insert Odyssey calls Ai-STAR, a urethane striking surface over an aluminium backer, tuned a touch firmer than the Ai-DUAL insert on the current 2-Ball and number 7 models. The head is a steel body with an ABS shell and an aluminium sole, and it comes with a Stroke Lab shaft, the SL120 as standard, with lighter SL90 options reported on some models. Specs on shaft weight and the exact sole weights still vary between sources before the full US launch, so treat the fine detail as close-to-final rather than final.
How it's being received
Early reviews are among the best we've seen this year. Today's Golfer scored it 4.9 out of 5. Forbes reported rolling in the first eight putts from around ten feet with the Max, and Amateur Golf called the alignment the easiest thing about the putter. The common theme is forgiveness and an easy, square aim, which is exactly what most golfers need from a putter.
Who it's for, honestly
High MOI, strong alignment and a tunable sole are the three things that help a higher-handicap putter the most, so on paper the TRTL is a very good fit for the golfer who three-putts too often. Two honest caveats. It's brand new, so the glowing reviews rest on limited rounds, and at $349.99 to $399.99 it's a premium putter, so it's a want rather than a need when a forgiving mallet at half the price will also do the job. If you want the adjustability and the alignment, though, this is the most convincing new mallet of the year.

FAQ
What is the Odyssey TRTL putter?

How many TRTL models are there, and which should I pick?
Four. The S, DB and CH are mid-mallets with two alignment lines, so pick the head shape and look you prefer. The Max is a larger zero-torque Square 2 Square model built to keep the face square, and it's the pick if you tend to open or close the face through the stroke.

It launched in Japan in August 2026 and reaches the US on 6 November 2026, with the UK and other markets to follow.
Is the TRTL a good putter for a high handicapper?
On paper, yes. High forgiveness, easy alignment and a tunable sole are the three things that help a higher-handicap putter most. The main caveats are that it's new, so reviews rest on limited rounds, and at a premium price it's a want rather than a need when a cheaper forgiving mallet will also do the job.
