The EQUS irons are unlike any other iron set on the market. The unique combination of weights, lengths and lofts are unique to the golf industry today.
By reducing the number of swings necessary to hit each iron in this set, by default, EQUS irons provide more reproducible swings and therefore improved consistency from club to club when compared to traditional iron sets. With swing consistency comes improved ball striking, which in turn leads to better scoring on the golf course.
Below are the salient points for the EQUS A-1 Irons.
1. Within each club in a given combination, in addition to identical weight and length, there is an identical CG (in 3 axes), relative to the club face. This results in identical launch conditions for each club within the same combination with the only variable being loft. This patent pending approach is not seen with traditional clubs of different CGs, weights and lengths.
2. EQUS Golf’s patent pending length and loft combinations utilizes increased loft of sequential clubs in each combination offset by matching increased length resulting in identical gapping between sequential clubs both in and between combinations. Human and robotic testing of > 3,000 swings at Golf Labs in San Diego provided validation of this concept.
Traditional lofts (4 – PW) 24 27 30 34 38 42 46
Length 38.5 38.0 37.5 37.0 36.5 36.0 35.5
EQUS lofts* (4 – PW) 24 28 32 34 39 44 46
Length 38.5 38.5 38.5 37.0 37.0 37.0 35.5

3. EQUS clubs were purposely designed with no ancillary weighting structures, inserts, ferrules or badges while still achieving matching CGs and tolerances surpassing industry standards.
Industry head weight tolerances +/- 3.0 grams
EQUS head weight tolerances < +/- 1.0 grams
Industry loft tolerances +/- 1.0 degrees
EQUS loft tolerances < +/- 0.5 degrees
Industry swing weight tolerances +/- 1.0 SW points
EQUS swing weight tolerances < +/- 0.5 SW points
Industry length tolerances +/- 0.125 inches
EQUS length tolerances < +/- 0.0625 inches
4. The unique weights, lengths and lofts of EQUS club heads required a design from scratch. This design, incorporating matched centers of gravity (CG) using a single piece of 431 stainless steel, required over 1,000 CAD hours to complete. The EQUS design is consistent throughout the entire set and unlike traditional irons does not radically change when reaching the short irons (wedges).
5. EQUS irons have components of all three club distinctions.
Overall we consider this a game improvement iron based on traditional lofts.
6. Bryson’s DeChambeau’s equipment and approach to golf has championed the single length iron concept and altered many of the perceptions of traditional golfers however, earlier attempts at single length irons have proved to extreme of a change to be universally accepted by the golfing market. Tommy Armour produced the EQL irons in the 1980’s where every club within the set was a 6-iron length. In 1998 1-Iron Golf debuted followed by recent additions by both Tom Wishon and Cobra Golf.
Although the merits of single swing mechanics using single length irons sounds promising, the diverse specifications of mid-length wedges and mid-length long irons might prove difficult for most customers to overcome. The EQUS irons are simply an evolution of the single length concept and traditional clubs.
7. EQUS golf irons are MOI (Moment of Inertia) matched for each set (see specifications). The result is a progressive swing weight, constant within each individual combination, and progressive in subsequent combinations. This allows a repeatable swing using multiple clubs without the awareness or perception of change. Each combination of irons projects the same “feel”, unrecognizable when compared, except for loft.
8. Hand built to order, these unique irons were designed to adapt to all levels of play. The ability to customize each set of irons to individual golfer’s abilities further distinguishes EQUS Golf. All EQUS Golf clubs are hand assembled in Austin, Texas by Jeff Sheets Golf. With over 28 years of experience in designing, fitting and customizing golf equipment Jeff Sheets, a Master Club Fitter, leads all assembly and customization.
9. In an EQUS golf set, the 10, 11 and 12 irons replace traditional wedges while retaining the traditional markings of P, W, L and S. These clubs are a progressive continuation of the lower lofted combinations in both specification and design. The result is a four wedge system utilizing only three lofts.
The EQUS golf combinations use a 12L wedge designed with the same loft as the 12S while utilizing the same lower bounce found in both the 10P and 11W. This combination helps simplify decision making around the green by eliminating loft (i.e. distance) as a variable. The club is chosen based on the playing conditions alone and not the distance desired.
SUMMARY
Narrowing the golfer’s swing mechanics down to only three golf swings is a derivation of both single length and traditional irons. Using matched combinations in three progressive lengths, these clubs allow golfers to easily transition to the single length concept without changing their current swing or giving up standard grips, lies or the traditional lengths found in long, mid and short irons. This concept is designed to improve consistency, ball striking ability and therefore, performance for golfers of all levels thus, making golf an easier game for all to play.
