Every archer produces grip torque. The hand isn’t a neutral point of contact — it applies small rotational forces to the riser during every shot, and those forces vary. Torque tuning doesn’t fix that. It adjusts the rest position until the variation no longer costs you on the target.
What grip torque is
Grip torque is rotation of the riser around its vertical axis during the shot. It happens because the hand can’t apply perfectly neutral contact force every time. A slightly tighter grip on one side, a small wrist deviation, a finger that presses differently at full draw — any of these sends the riser rotating.
The arrow itself isn’t directly affected by riser orientation at the moment of release — it leaves the string, not the riser. But the rest is attached to the riser, and the rest is the point from which the arrow departs. When the riser rotates, the departure geometry changes. The arrow leaves at a slightly different horizontal angle depending on which direction you torqued, and by how much.
You cannot see this happen in real time. You can only see it after the arrow lands.
What torque tuning is
Torque tuning is a ratio adjustment. Two pieces of equipment are offset from the riser’s natural pivot point — the rest and the sight. The sight reaches out in front of the pivot; the rest sits behind it. When the bow torques, these two items swing in opposite directions. The ratio of their distances from the pivot determines how much each contributes to where the arrow lands.
When the ratio is wrong, torque costs you. When the ratio is right, the two effects cancel — and torque variation stops mattering.
It does not make your grip more consistent. It does not stop you from producing torque. It finds the geometry where torque variation is self-correcting.
The procedure
The most common method uses a vertical reference line — the edge of a target face, a strip of tape, anything that gives you a clean vertical to aim at. Set up at 20 to 30 yards in calm conditions.
Step 1. Shoot one arrow with your neutral grip, aimed directly at the vertical line. It should land on the line. If it doesn’t, adjust your aim until it does — this shot sets your horizontal reference, not your score.
Step 2. Below that arrow, shoot one arrow with deliberate left torque — more than feels natural, but not forced. Aim at the same vertical line. Note how far left or right of the line it lands.
Step 3. Below that, shoot one arrow with deliberate right torque. Same drill — aim at the line, note where it lands relative to it.
Step 4. Read the result. Three outcomes are possible:
Equal distance, one on each side of the line — this is the expected starting result. The gap between the two arrows is your torque contribution — the magnitude of torque you applied. Adjustments are warranted. This is where the tuning process begins, not where it ends.
Both arrows on the line — done. The ratio is cancelling the torque completely at this distance.
Both arrows on the same side of the line — the bow has a left or right issue in its basic tune, consistent with a left or right paper tear. Torque tuning cannot resolve this. Address the underlying tune first, then return.
Unequal distance, opposite sides — the basic tune is slightly off, or the bow carries an intentional horizontal bias. The process is the same: close the gap between the two extremes until the arrows land equal.
Step 5. Read where the torqued arrows landed relative to the line, then adjust:
If a torqued arrow landed on the same side as the torque — left torque lands left, right torque lands right — the sight is not sweeping enough to cancel the effect. Extend the sight outward to increase the sweep.
If a torqued arrow landed on the opposite side from the torque — left torque lands right, right torque lands left — the sight is sweeping too far and overcorrecting. Bring the sight back inward to reduce the sweep.
Re-shoot and read the result again. Keep adjusting until all three arrows land in a vertical line on the reference: neutral on the line, left torque on the line, right torque on the line.
Why it works — the pivot and the ratio
The riser pivots around a natural vertical axis at the grip. Items mounted forward of that pivot swing one direction under torque; items mounted behind it swing the other.
The sight bar extends forward. Torque the bow right — the pin moves right. The farther the sight extends from the pivot, the larger the arc it sweeps for a given amount of torque.
The rest sits close behind the pivot — much closer than the sight. Torque the bow right — the rest moves left. Here is where compound bows do something that catches most archers off guard. When the rest moves right, the rear of the nock is sent right on the launch, which pushes the arrow tip left. The arrow goes left. When the rest moves left, the arrow goes right. The rest’s effect on point of impact is opposite to its direction of movement.
So under right-hand torque: the pin moves right and the rest creates the conditions for the arrow to go right.
The rest is much closer to the pivot than the sight. Its lever arm is shorter, its contribution is smaller. Torque tuning finds the specific ratio at which the two effects are equal and opposite — and torque becomes a non-event.
What to adjust — sight or rest
Once you know the ratio is off, you have two ways to fix it: move the sight or move the rest.
Most archers adjust the sight. Modern sights are designed to accommodate forward and backward movement of the bar. Moving the sight forward increases its distance from the pivot — the pin sweeps more arc per degree of torque, the sight’s corrective contribution increases. Moving it back does the reverse. This adjustment is clean, repeatable, and doesn’t disturb anything else in the tune.
Some rests can be moved backward on the riser, increasing the rest’s distance from the pivot and increasing its effect on arrow departure. This is a legitimate adjustment, but it carries more risk. The rest is the foundation of arrow flight tune — nocking point height, center shot, and walk-back tune all reference rest position. Moving the rest to fix a torque ratio problem can introduce new problems elsewhere that then need to be re-addressed. Most archers leave the rest alone and adjust the sight.
The exception is archers using magnification. A scope with a specific housing or magnification relationship fixes the eye-to-aperture distance — moving the sight bar changes that relationship and may degrade the optic. For these archers, the rest is the only available adjustment.
Bias-compensated torque tuning
The vertical line procedure assumes the sight bar is positioned within a range where full torque cancellation is achievable at your shooting distance. For many target archers, it isn’t. A common indoor setup has the sight bar extended 7 inches or more — necessary for sight radius and for magnification to function correctly. At that extension, the tuning window may fall short of your actual distance. Full cancellation isn’t available.
When you run the procedure in this situation, the torqued arrows won’t converge on the line no matter how you adjust. The sight is simply too far out for the ratio to fully cancel at your distance. That’s not a failure — it’s a constraint of the setup. What it means is that torque variation costs more, and grip consistency becomes more important.
There is, however, a way to use this asymmetry to your advantage. When the sight is past the tuning window, an intentional horizontal bias in the arrow tune shifts which direction of torque hurts more. One direction will produce a larger deviation than the other. You get to choose which one.
If you naturally torque left, set the bow’s intentional bias to the side that reduces the torque output in the left direction. Your natural tendency becomes the forgiving direction — the one that lands closer to the line. Your deliberate overcorrection in the other direction lands farther out, but you’re not naturally doing that. The result is a bow that self-corrects for the grip error you actually make.
This is not a substitute for proper torque tuning at the achievable distance. It is a second layer of management for setups where full cancellation isn’t on the table. The bias article covers how to set and evaluate intentional horizontal bias in detail.
What the tune delivers
Torque tuning is worth doing. The procedure is straightforward, the result is observable, and at the tune distance the improvement in group consistency is real. Both torque directions landing at the same point means your worst torque variation no longer produces the largest group spread — it produces the same impact as your best torque variation, because the rest position equalized the cost.
What it doesn’t deliver is consistency across all distances, or a correction that compensates for genuinely inconsistent grip mechanics. If your torque varies so wildly that neither group is stable enough to locate, the underlying grip problem needs attention before the tuning procedure can produce a clean result. The tune equalizes two paths. It can only do that if each path is actually there to be found.
