Recurve Limbplane Alignment Toolset

Learn More


Five years in development. Over 30 prototypes. Tuning Forks™ are the first toolset of its kind for fast, accurate alignment to the real 3-D center of your recurve. 

This is alignment done right. This is confidence made visible.


The 3D Limbcentric™ design reveals each limb's 3-dimensional geometric center called the limbplane. It's the optimal string position for limb stability.

See it. Align it. Get back to doing absolutely anything else.


The process is simple. XAlign™ helps you get both limbplanes aligned and working together in 3D space. 

No more head-scratching. Just accurate results.



    See your bow's optimal limb alignment in 3D. No parallax errors, no guesswork.


    Spot twisted limbs & risers during alignment—no additional tools required.


    Cut post-shot noise & vibration (vs. misaligned bows).


    Accurately adjust centershot, sight rail & front stabilizer for complete bow alignment.


    The quick and clear step-by-step manual won't leave you hanging.


Will I receive 1 or 2 Tuning Forks?

Like shoes or pants, they come in pairs. You'll get 2 Tuning Forks + 1 protective case per set ordered. 

Are they compatible with my bow?

Probably! They're designed to work with limbs from all the major recurve brands—even the really narrow ones.


If you have custom accessories installed on your limbs (vibration dampeners, limb skins, etc) extra care should be taken to avoid damage during use though.

How are they different from other methods?

Tuning Forks are unique in both design and method of use—they're a simple tool that solves a complex problem. Limb alignment is a puzzle. And now you have the picture on the box.

3D Design - Eliminates parallax errors by providing a visual reference for absolute center in 3D space.

Limbcentric - Uses only the geometric center of the limb—the limbplane—as reference for alignment. They do the work, they're the boss. No arbitrary holes or riser surfaces are used. It's called limb alignment, why use anything else?

XAlign - Get both limbplanes into alignment quickly and accurately thanks to the Limbcentric 3D design. Align the top of one to the bottom of the other, repeat. Done.

Are there any issues with limb clear coats?

Tuning Forks provide surprisingly consistent readings of limbs given the nature of limb coatings. The design of the arms allows for variation of the limb surface while maintaining accuracy—within reason. Limb damage, limb decals, or significant clear coat deformity might influence results. The manual covers the suggested method for checking limb surfaces for accuracy prior to adjustment.
