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.
