The putting solution designed to improve consistency, confidence and performance.
Feature Models
373G – The Original
Pure geometry. True feedback. Real progress.
The 373G is the original iBPutter Sweet Spot design — the model that set the DNA for everything that followed.
With a centered shaft, Zero Torque geometry, and cylindrical alignment zone, it promotes a clean, balanced, pendulum-like stroke. Its slightly heavier head adds stability, precision, and rhythm.
It’s a demanding putter, designed for players who want to grow.
Because to improve on the green, you have to challenge yourself —
and the 373G does exactly that.
Be Different
410G – Precision With Presence
More weight. More control. More confidence.
The 410G was the second model in the iBPutter Sweet Spot line, evolving directly from the 373G and preserving its design DNA while increasing the head weight from 373g to 410g.
This added mass enhances stability, rhythm, and control through the stroke — especially under pressure — giving the player a firmer, more anchored feel at impact.
Like the 373G, it features a centered shaft, Zero Torque design, and cylindrical visual geometry that promote a square, pendulum-style motion.
Demanding yet rewarding, the 410G is for players who want more feedback, more presence in the stroke, and ultimately, better results on the green.
Be Unique
BX2 – Evolution in Balance
The BX2 represents the natural evolution of the iBPutter Sweet Spot concept — a putter that preserves the core principles of the brand while offering a more conventional silhouette.
It retains the essential features: centered shaft, Zero Torque geometry, and symmetrical design, but introduces refined lines, a more compact profile, and enhanced playability for a wider range of players.
Balanced, clean, and intuitive at address, the BX2 delivers the same feedback and control expected from all iBPutter Sweet Spot models, but with a shape that feels instantly familiar.
Designed for golfers who seek precision, simplicity, and performance in a modern form — without compromising the DNA that defines us.
Be Better
Quaternion – Mathematics meets motion. Stability meets feel.
The Quaternion is the most conceptual and technically advanced model in the iBPutter Sweet Spot collection.
Its name is inspired by quaternion mathematics — a complex number system used to describe three-dimensional rotation — perfectly aligned with the core idea of putting: a symmetrical, controlled motion in space without distortion or torque.
Built with a centered shaft, true bilateral symmetry, and a unique cylindrical head structure, the Quaternion delivers exceptional visual alignment and stroke balance.
It also features our anti-vibration shaft system, designed to absorb unwanted feedback and amplify the sensation of a clean, centered impact — allowing the player to focus purely on rhythm, control, and flow.
This is a putter for players who appreciate pure geometry, refined feedback, and a stroke that feels as balanced as it looks.
What They Say
I believe the iB Putter Sweet Spot is a magnificent club for any player looking to improve their game on the green. I would highlight the club's ability to help the player concentrate more on the putting process, as well as its cylindrical shape and balanced weight of its head, which contribute to a more on-target stroke. Personally, it's a club I highly recommend.
Ever since I tried the iB Putter Sweet Spot, I've been using it consistently in my training sessions. One of the standout features of this club is its ability to promote an exceptional stroke on the correct plane, which significantly helps me achieve great results. Its well-balanced weight also gives me a sense of stability and confidence. Undoubtedly, it's a club that makes a notable contribution to improving results on the green.
It doesn't surprise me at all the success of these putters, given my familiarity with Iván Ballesteros and his extensive experience in the golf industry. The 373G counts with a spectacular touch. I don't believe there's a better putter for distances of 4 meters to the hole. From the outset, it has been one of the 14 clubs in my bag, and I'm delighted with it!
In 2006, Ivan Ballesteros played a crucial role in MD Golf's development of golf equipment under the legendary name of Seve Ballesteros. Leveraging his profound knowledge as a professional player and close relation to Seve, Ivan contributed significantly to the project. His deep understanding of golf equipment served as a guiding force. The innovative concept he has developed in these putters reflects his continued commitment to elevating golf equipment standards.
