Darton Tritech 31 70lb Compound Bow

Darton TriTech 31 — The Most Tunable Compound Bow on the Market

76 years of excellence and innovation in archery — and the TriTech 31 is Darton's latest statement of what that legacy means. Built around three patent-pending technologies that make perfect tuning and timing achievable for any archer at any experience level, the TriTech 31 is a precision-tuned powerhouse in a compact 31 3/16-inch axle-to-axle package. The smoothest draw cycle imaginable, unmatched consistency, and the most tunable platform on the market today — all Made in the USA.

Three Patent-Pending Technologies

Dual-Function Micro-Adjust Roller Guard (Patent Pending)

The patent-pending dual-function micro-adjust roller guard is one of the TriTech's most significant innovations. It allows you to make precise, repeatable adjustments to your cable position without a bow press — tuning your arrow flight and cam lean directly, with confidence. Whether you're dialing in paper tune or chasing bullet holes at distance, the micro-adjust roller guard gives you the control to get there without a shop visit.

Perfect-Timing Adjustable Yoke Hangers (Patented)

The improved patent-pending Perfect-Timing Adjustable Yoke Hangers give you direct control over cam timing — the most critical factor in consistent arrow flight and draw cycle feel. Quick, precise adjustments with new additional laser engravings make timing adjustments faster and more repeatable than ever. Spend less time tweaking and more time shooting.

Perfect-Tune™ Adjustable Limb Pocket System (Patent Pending)

The patent-pending Perfect-Tune™ Adjustable Limb Pocket System allows you to make cam lean adjustments without removing the bow from the press — or without a press at all. Combined with the roller guard and yoke hanger adjustments, the TriTech 31 can be tuned to perfection without specialized equipment or a shop visit. Darton's innovations make getting a bow tuned absolutely perfect genuinely possible.

Key Features

BBS Dual Sync Cam — 1/4" Draw Length Adjustments

The BBS Dual Sync Cam (also known as the Sequel Cam, patent 6,990,970 B1) delivers the smoothest draw cycle imaginable with 1/4-inch draw length adjustments using rotating modules. Most bows offer 1/2-inch increments — the TriTech 31's 1/4-inch adjustability gives you a level of fit precision that makes a real difference in draw feel and accuracy.

Patented Deep Groove Cam (#8,714,143)

Darton's patented Deep Groove Cam design maintains consistent string tracking and reduces string derailment potential under all shooting conditions. It's a structural detail that contributes to the TriTech's unmatched consistency shot after shot.

QAD Integrated Rest Mount

The QAD Integrated rest mount is built directly into the riser, providing the most compact and stable rest connection available. Direct-to-riser integration eliminates the gap and leverage point of a traditional rest mount, resulting in more consistent rest position and improved arrow flight repeatability.

Picatinny Sight Mount

A Picatinny sight mount is included for direct, rigid sight connection. The Picatinny interface is compatible with a wide range of premium hunting and target sights and eliminates the flex and movement of standard dovetail mounting.

Sanoprene Grip — Three Options for Perfect Fit

The new, softer Sanoprene Grip insert makes the TriTech 31 more comfortable to shoot, especially on cold mornings when hand feel matters most. Three grip options are available: Neutral (installed on the bow), 2.5 degree, and 5 degree — allowing every shooter to find the grip angle that matches their style and hand position perfectly.

Speed Mod Included

A speed mod is included with the TriTech 31 (not pre-installed) that adds an additional 5-6 fps to your setup. Install it when you want the extra speed, or run the standard mod for a smoother draw cycle. Two draw stop post sets allow micro-adjustment of your let-off within the 75%-83% range.

Custom-Made Bowstrings

Every TriTech 31 ships with custom-made bowstrings built specifically for this platform — not off-the-shelf strings adapted to fit. String quality is critical to consistent performance, and Darton doesn't compromise on it.

Made in the USA

Every TriTech 31 is made in the USA at Darton's facility in Hale, Michigan. 76 years of American archery manufacturing behind every bow.

Who It's Built For

Why Extreme Outfitters Recommends It

Darton has been building bows in Michigan for 76 years and the TriTech 31 is the clearest expression of what that experience produces. The three patent-pending tuning technologies — micro-adjust roller guard, Perfect-Timing yoke hangers, and Perfect-Tune limb pockets — aren't marketing features. They're engineering solutions to real tuning problems that archers deal with every time they set up a new bow. If you want a compact hunting bow that you can tune to perfection without a bow press, the TriTech 31 is the most capable option available at this price. Our techs can set it up to your exact draw length and get it shooting right before you leave the shop. Call us Monday through Saturday — real people answer the phone at Extreme Outfitters.

Frequently Asked Questions

What are the three patent-pending technologies on the TriTech 31?

The TriTech 31 features: (1) the Dual-Function Micro-Adjust Roller Guard for cable position and cam lean adjustment, (2) the Perfect-Timing Adjustable Yoke Hangers for cam timing control, and (3) the Perfect-Tune™ Adjustable Limb Pocket System for additional cam lean adjustment. Together, these three systems allow an archer to fully tune their bow without a press — a first in this price class.

What draw lengths does the TriTech 31 cover?

The TriTech 31 covers 25 to 30.5 inches of draw length in 1/4-inch increments using rotating modules. If you need help setting your correct draw length, our techs can do that in the shop at purchase.

What is the difference between the standard mod and speed mod?

The standard mod is installed on the bow from the factory. The speed mod (included but not installed) adds 5-6 fps and also changes the draw cycle feel — it can make the letdown a bit more aggressive. Most hunting shooters prefer the standard mod; archers prioritizing maximum speed can install the speed mod.

How does the 1/4" draw length adjustment work?

The BBS Dual Sync Cam uses rotating modules that adjust draw length in 1/4-inch increments — twice the precision of standard 1/2-inch adjustment systems. This means most shooters can find their exact draw length without cable twisting or other workarounds that affect bow performance.

What colors are available at Extreme Outfitters?

This SKU at Extreme Outfitters is available in FDE/Black, OD Green/Black, and Stone Grey/Black. Contact us for current in-stock availability on each color.

Is the TriTech 31 a good fit for hunting?

Yes. The 31 3/16-inch axle-to-axle and 6 3/8-inch brace height make it a well-rounded hunting platform — compact enough for treestand and blind hunting while still providing the stability that comes with a longer ATA. The QAD Integrated rest mount and Picatinny sight mount are both designed with practical hunting use in mind.
