Tru-Ball HBX Pro (2022): A Tournament-Grade Index Release Built for Reliability

Index-finger releases are the most common release style in compound archery, and most shooters learn on them. The problem is that most entry-level index releases actively train bad habits: the trigger is heavy, the sear travel is long, and the break is soft enough that shooters learn to anticipate the shot and punch the trigger rather than maintain back tension through the break. The HBX Pro exists to offer a trigger mechanism that demands the opposite — a short, clean break that rewards a genuine surprise shot and punishes punching with a low group.

What's notable

The HBX Pro uses a machined aluminum body with a rotating head that adjusts independently of the wrist strap. Head rotation lets the shooter set the trigger position relative to the bow at full draw without twisting the wrist strap to compensate — a significant fitting variable that most club-level shooters never address but that makes a real difference in trigger accessibility and consistent finger placement. The head angle adjustment is tool-free; a locking collar releases with a push-button and resets with an audible click.

The trigger uses Tru-Ball's short-sear design, which reduces trigger travel to a fraction of what budget index releases require. The feel is a defined wall and a clean break — closer to a well-tuned rifle trigger than the rolling action of a standard caliper release. Travel from the wall to the break is adjustable via a set screw at the sear; turning it in reduces travel and lightens the pull, turning it out increases both. The adjustment range is intentionally narrow — the trigger can't be set light enough to be genuinely dangerous, but the window is wide enough to accommodate personal preference across a range of hand sizes and grip styles.

The jaws are stainless steel with a positive locking latch mechanism that won't accidentally close on a string loop while nocking an arrow in low light. The release throat is deep enough to seat a standard Tex-Lok or BCY serving loop cleanly, and the jaw geometry is forgiving enough that a shooter who seats the loop slightly off-center doesn't get a left-right error in the shot. The wrist strap is leather-backed nylon with a Velcro closure — straightforward to replace when worn without ordering a proprietary part.

Who it's for

The HBX Pro is built for intermediate and advanced compound archers who shoot index-finger releases and want a trigger mechanism that holds up across a tournament day. NFAA field archers, 3D competitors, and indoor target archers who shoot 600 or 1200 round scores know that trigger fatigue is real — a trigger that requires extra conscious force after 30 shots produces flinch and punch errors that don't show up early in a round. The HBX Pro's short sear and clean break reduce that fatigue load. The head rotation adjustment is especially useful for archers who've struggled to find a comfortable trigger angle after experimenting with different frame orientations.

Beginners can run this release, but they'll realize the benefit only once their form is stable enough to feel the difference between a genuine back-tension break and a punched shot. A coach who introduces a developing shooter to the HBX Pro's trigger early is making a form investment that pays off over years, not rounds.

Where it sits in the lineup

Tru-Ball's 2022 index release lineup ran from the standard HBX (lighter body, fixed head, basic trigger) through the HBX Pro to the HBX Pro Plus, which added a removable trigger module for competition-level customization. The Pro sits at $90–$110 retail — mid-tier for a tournament-grade index release. Carter, Scott, and Stan position equivalent competition index heads at similar or higher price points; Tru-Ball competes by offering equivalent trigger quality with more frame adjustability than most competitors provide at this price.

For NFAA 3D and indoor shooters who shoot multiple disciplines and need a single release that functions consistently across shooting positions — standing, kneeling, sitting — the rotating head is a practical advantage. Compound 3D shooters move through a range of body angles during a course round, and a head that adjusts to keep the trigger position consistent relative to the draw hand reduces the number of variables that change between shots.

The HBX Pro also functions as a practical backup release for back-tension and thumb-trigger shooters who need an index release for a specific round format or for coaching demonstrations. Its trigger feel is clean enough that transitioning from it to a thumb trigger doesn't require relearning the shot sequence from scratch. Coaches running clinics will find the head-rotation adjustment useful for fitting the release to multiple student hand sizes without swapping wrist straps mid-session — a small time-saver that adds up across a full day of instruction.
