The Darton TriTech 31 V2 Compound Bow combines advanced tuning technology, customizable shooting characteristics, and a compact 31 3/16-inch axle-to-axle platform built for serious bowhunters. Building on the original TriTech 31, the V2 introduces a redesigned lighter riser, updated limb pockets, titanium hardware, and Darton's FAST Arrow Tune Indicator while retaining the extensive tuning capabilities that define the TriTech series.
With a 6 3/8-inch brace height, a manufacturer-listed mass weight of 4.32 pounds without the included LVS installed, and the BBS Dual Sync Cam System, the TriTech 31 V2 offers a combination of compact hunting geometry and advanced adjustability. Perfect-Tune limb pockets, tool-less Perfect-Timing yoke hangers, a micro-adjustable roller guard, and quarter-inch draw-length adjustments give bowhunters and bow technicians multiple ways to fine-tune the setup.
Key Features
Redesigned, Lighter Riser
The TriTech 31 V2 features a redesigned riser that reduces overall mass compared with the original TriTech 31. Darton also updated the limb-pocket design and incorporated titanium hardware as part of the new platform.
At 4.32 pounds without the included LVS installed, the V2 weighs approximately 0.18 pounds less than the original 4.5-pound TriTech 31.
For mobile bowhunters, reducing bare bow weight can be beneficial once a sight, rest, quiver, stabilizers, and other accessories are added. However, the balance and weight distribution of the finished setup matter just as much as the manufacturer's listed mass weight.
Compact 31 3/16-Inch Axle-to-Axle Platform
At 31 3/16 inches axle-to-axle, the TriTech 31 V2 is the most compact option among the standard TriTech 31, 33, and 35 V2 hunting models.
This geometry makes it especially appealing to whitetail hunters who spend time in treestands, saddles, and ground blinds where maneuverability can be important.
The shorter platform may also appeal to hunters who prefer less overall bow length when moving through thick cover or working around tight shooting windows.
However, shorter axle-to-axle length doesn't automatically make a bow better for hunting. Draw length, string angle, anchor position, holding stability, and shooting comfort should all influence the decision.
BBS Dual Sync Cam System
The Darton TriTech 31 V2 uses the BBS Dual Sync Cam System, also known as the Sequel Cam, incorporating Darton's patented Deep Groove Cam technology.
The cam system is designed to combine a smooth draw cycle with adjustable draw length, customizable let-off, and multiple module configurations.
For bowhunters, cam performance is about more than maximum arrow speed. How the bow builds weight during the draw, transitions into the valley, and holds at full draw all influence the shooting experience.
Comfort and Speed Module Options
Darton includes both standard comfort and speed module options with the TriTech 31 V2, allowing shooters to select their preferred balance between draw-cycle feel and speed potential.
In its standard configuration, Darton publishes an actual-speed rating of 334–335 fps. With the included speed module installed, the published rating increases to 339–341 fps.
An optional 75% module, sold separately, carries a manufacturer-published speed rating of 341–343 fps.
Speed Note: These are manufacturer ratings for the specified module configurations. Actual speed with a finished hunting arrow depends on draw length, draw weight, arrow weight, let-off, and the complete bow setup.
Quarter-Inch Draw Length Adjustment
The TriTech 31 V2 accommodates draw lengths from 25 to 30.5 inches with precise quarter-inch adjustments.
Many compound bows use half-inch draw-length increments, which can leave some shooters between their ideal settings. Quarter-inch adjustment provides additional flexibility when fine-tuning anchor position, posture, alignment, and shooting comfort.
Proper draw length is one of the most important parts of bow setup. Small changes can influence how naturally a bow points, how consistently the shooter anchors, and how the shot is executed.
Perfect-Tune Adjustable Limb Pocket System
One of the defining features of the TriTech platform is Darton's Perfect-Tune Adjustable Limb Pocket System.
Perfect-Tune provides precise, continuously variable limb-pocket adjustment, giving qualified bow technicians another way to refine bow alignment during tuning.
Instead of relying exclusively on rest movement or conventional cam-shimming procedures, technicians can use the limb-pocket system as part of the overall tuning process.
Proper arrow flight still depends on the complete system, including arrow spine, cam timing, rest position, nock fit, and shooting consistency.
Perfect-Timing Tool-less Micro-Adjustable Yoke Hangers
The TriTech 31 V2 incorporates Darton's Perfect-Timing tool-less micro-adjustable yoke hanger system.
This provides a method for making precise supported timing adjustments without relying exclusively on conventional cable-twisting procedures.
Compared with traditional tuning methods, convenient micro-adjustment can make it easier for experienced technicians to track changes and refine cam synchronization.
Laser-engraved reference marks help provide repeatable adjustment references.
Dual-Function Micro-Adjustable Roller Guard
The TriTech 31 V2 includes Darton's dual-function micro-adjustable roller guard, designed to allow precise cable-guard positioning without removing the cables.
Cable-guard position influences cable clearance and can affect the bow's alignment and tuning characteristics.
Having another adjustment option gives technicians additional flexibility when working through arrow flight and bow setup.
Always follow Darton's recommended procedures and verify proper clearance after making adjustments.
FAST Arrow Tune Indicator
The TriTech 31 V2 introduces Darton's FAST Arrow Tune Indicator, a precision-machined reference built into the riser.
The system is designed to help establish an initial arrow-rest alignment before paper tuning. By positioning one arrow against the riser reference and comparing it to an arrow on the rest, a technician can adjust the rest until the arrows run parallel.
This provides a repeatable starting point for initial centershot setup.
Tuning Note: FAST is an alignment reference, not a substitute for paper tuning, broadhead testing, or verifying arrow flight with the actual shooter.
Titanium Axles and Limb Bolts
The V2 features 1/4-inch button-head titanium axles and titanium limb bolts as part of Darton's updated construction.
These components contribute to the bow's lighter overall design while supporting the mechanical requirements of the limb and cam systems.
The bow also incorporates 5/8-inch cam bearings.
Adjustable Let-Off and Draw Stops
The TriTech 31 V2 provides adjustable let-off through its draw-stop and module configurations.
Darton lists an adjustment range of approximately 83% to 75%, depending on configuration, and includes two sets of draw-stop posts.
Let-off influences how much holding weight remains at full draw. Some archers prefer a lighter hold for extended aiming, while others prefer additional holding weight to maintain tension throughout the shot.
The optional 75% module is sold separately.
Interchangeable Grip Angles
The TriTech 31 V2 includes a factory-installed neutral grip with additional 2.5-degree and 5-degree grip-angle options.
These options allow shooters to experiment with wrist position, hand pressure, and the way the bow naturally settles into the grip.
The soft Santoprene grip insert is designed to improve comfort, including during cold-weather hunting.
Grip preference is personal. The best configuration is the one that promotes consistent hand placement without introducing unwanted torque.
Picatinny Sight Mounting
The TriTech 31 V2 includes a Picatinny sight-mounting interface for compatible bow sights.
Direct-to-riser mounting can reduce unnecessary brackets and help maintain a streamlined hunting setup.
Confirm compatibility with your preferred sight before selecting accessories.
QAD Integrate Rest Mounting
The bow features a QAD Integrate-style dovetail interface for compatible arrow rests.
This provides a direct mounting option intended to reduce additional hardware while maintaining secure positioning.
After installing a rest, arrow alignment and clearance should be verified as part of the complete tuning process.
Third Leg Bow Stand Compatibility
The redesigned limb pockets on the TriTech 31 V2 accept Darton's Third Leg Bow Stand attachment.
When used with the compatible Darton Foldable Bow Stand, this system is designed to keep the bow upright while lifting the lower cam off the ground.
This can be convenient during range practice, 3D events, and equipment setup.
Accessory Note: The Third Leg attachment and Foldable Bow Stand are sold separately.
Customizable Finish and Appearance
Darton offers the TriTech 31 V2 in multiple solid-color and camouflage riser finishes with black limbs.
Additional customization options include interchangeable side plates and multiple colors for grips and grip plates.
Available configurations depend on manufacturer and dealer inventory.
Made in the USA
The Darton TriTech 31 V2 is manufactured in the USA and comes equipped with custom-made bowstrings.
The design emphasizes precise fitting, extensive adjustability, and the ability to tune the bow to the individual shooter.
Who It's Built For
The Darton TriTech 31 V2 is designed for bowhunters who want compact hunting geometry without sacrificing advanced tuning technology or precise adjustability.
It is particularly well suited for shooters who:
- Prefer a compact 31-inch hunting bow.
- Primarily hunt whitetails from treestands, saddles, or ground blinds.
- Want maneuverability in confined hunting environments.
- Value the tuning flexibility of Perfect-Tune limb pockets.
- Want tool-less timing adjustment and a micro-adjustable roller guard.
- Prefer quarter-inch draw-length adjustment for precise fitting.
- Want comfort and speed module options.
- Value interchangeable grip angles and adjustable let-off.
- Want modern Picatinny sight and Integrate arrow-rest mounting.
- Are considering upgrading from the original TriTech 31.
The TriTech 31 V2 is also worth considering for bowhunters who want the same core tuning technology found in Darton's longer TriTech V2 models but prefer a shorter platform.
Shooters with longer draw lengths or those who prefer a more open string angle may want to compare the TriTech 33 V2 or TriTech 35 V2 before deciding.

Which should you choose? The TriTech 31 V2 emphasizes compact maneuverability, making it a logical option for treestand, saddle, and ground blind hunting. The TriTech 33 V2 offers a middle-ground platform for hunters who want versatility, while the TriTech 35 V2 provides longer geometry that may appeal to shooters who prefer a more open string angle and the aiming characteristics of a longer bow.
All three provide the same core tuning systems, so the right choice should come down to proper draw-length fit, holding characteristics, bow balance, and shooting preference rather than assuming that one axle-to-axle length is automatically more accurate.
Our Take on the Darton TriTech 31 V2
At Extreme Outfitters, we evaluate compound bows based on the complete shooting experience rather than relying on advertised speed alone.
Draw cycle, valley, grip, holding stability, tuning flexibility, and how a bow performs with a finished hunting arrow all influence whether it is right for a particular shooter.
The TriTech platform has stood out to us because of the amount of tuning adjustability Darton builds into the system. The original TriTech 31 already offered limb-pocket adjustment, micro-adjustable timing, and cable-guard tuning that separated it from many other hunting bows.
With the 31 V2, Darton retains that core approach while refining the riser, limb pockets, hardware, and initial tuning process.
The most obvious difference is the lighter construction. Reducing the bare weight from 4.5 to 4.32 pounds is a welcome change for a compact hunting bow, especially when the finished setup includes a sight, quiver, and stabilizers.
We also like the combination of the Perfect-Tune limb pockets, Perfect-Timing yoke hangers, and the micro-adjustable roller guard. These systems give a bow technician multiple ways to work through tuning rather than relying on a single adjustment.
The new FAST Arrow Tune Indicator is another useful addition. Establishing a consistent initial alignment can help simplify setup, but we would still verify the finished tune through paper tuning and actual arrow flight.
For whitetail hunters, the 31 3/16-inch axle-to-axle platform is one of the main reasons to consider this model over the longer TriTech V2 bows. It provides a more compact setup for hunters who routinely deal with limited shooting clearance.
However, shorter isn't automatically better. Shooters who prefer the string angle and holding characteristics of a longer bow should compare the 33 V2 and 35 V2 as well.
We also appreciate the quarter-inch draw-length adjustment and interchangeable grip angles. Small fitting changes can make a noticeable difference in anchor position, hand placement, and how consistently a bow aims.
The included comfort and speed modules add another decision. Rather than automatically choosing the fastest configuration, we recommend selecting the module that delivers the best combination of draw comfort, holding feel, and consistent execution for the individual shooter.
For bowhunters who want a compact flagship hunting bow with extensive tuning capability, customizable ergonomics, and updated lightweight construction, the Darton TriTech 31 V2 deserves serious consideration.
Our recommendation is to evaluate it at your actual draw length and preferred draw weight, then determine how it draws, holds, and balances with your intended hunting accessories.
