Welcome to the future of golf. The Wishon EQ1 Single Length Golf Clubs are designed for consistency, precision, and performance.

The Main Transformation

For decades, golf forced players to adapt to 8 different iron lengths, 8 different stances, and 8 different swings. The EQ1 completely rewrites this paradigm, delivering surgical precision through absolute single-length consistency.

The Variable Length Dilemma

Traditional iron sets demand continuous athletic compensations. As club length shifts, your posture, ball position, and swing plane must constantly adapt, introducing a high margin of error.

The EQ1 Paradigm Shift

By engineering every single iron to match the exact same center of gravity, swing weight, and physical length, you lock in one singular, perfect athletic motion. Every club feels exactly the same.

Experience the mechanical simplicity of a singular, repeatable motion. Explore Single-Length Specs

WISHON EQ1 // HIGH-CONTRAST ENGINEERING REVEAL

DECONSTRUCTED GEOMETRY

Explore the structural innovation of the EQ1 Single-Length Iron. Every facet is CNC machined for identical swing feel, center of gravity placement, and optimal loft-to-lie ratio.

01 // CNC GROOVE PRECISION

Traditional GW and SW profile shapes are combined with milled faces and a custom sole grind make the wedges a great choice even if they were standalone wedges and not part of the single length design

02 // CG ALIGNMENT CAVITY

Enabled by the new 2-piece hollow body design, the Center of Gravity moves progressively through the set from lowest and most rear located on the #5 iron to highest and most forward located on the GW and SW to achieve more consistent shot shape and shot height for each iron in the set

03 // CONSTANT HOSEL OFFSET

A specialized bore design and uniform progressive 2 mm offset allows players to utilize the exact same posture, alignment, and ball address profile throughout the set.

04 // TURF RELIEF SOLE

Crafted with a custom leading edge radius that offsets aggressive turf interaction. The design reduces deceleration, optimizing energy transfer at the critical point of impact.

01 / WEIGHT SYSTEM

Uniform Weighting

275g head weight with hosel weight bore allows assembly to any single length between 35.5” and 37.5” while still being able to achieve a reasonable range of swingweight/MOI (depending on shaft weight and grip weight)

02 / FLIGHT DYNAMICS

Consistent Ball Flight

With an optimized center of gravity matched across the lineup, the EQ1 delivers precise ball flights and identical launch vectors. Spin decay rates and peak heights lock in, minimizing club-to-club variance and producing tight shot dispersions.

03 / SPECIFICATIONS

Precision Loft Gapping

We solved the yardage gap problem that plagues traditional matched sets. Low number irons are better matched with their loft to CG position to achieve preferred shot shape/height and allow a wider range of players to be able to effectively hit the #5 and 6 irons to fly and carry with proper distance gaps

REAL-TIME PERFORMANCE DATA

THE QUANTIFIABLE DIFFERENCE

Engineered for maximum velocity and extreme stability. High-speed launch monitors confirm the devastating precision of the EQ1 modern design.

CONSISTENCY

0 %

Tested and verified performance ensures identical launch angles and optimized spin rates on off-center hits.

MORE ACCURACY

+ 0 %

Advanced weight distribution technology increases MOI, tightening shot dispersion metrics by fifteen percent.

THE EVOLUTION OF PRECISION

Variable lengths introduce endless adjustments. The EQ1 single-length system locks in one repeatable swing for ultimate on-course consistency.

THE OLD WAY

Traditional variable-length sets require you to adapt your posture, ball position, and swing plane for every single iron in your bag.

THE EQ1 WAY

By matching every iron in length, weight, and balance, the EQ1 allows you to execute the exact same swing plane with absolute confidence.
