Objective
Make the bow more forgiving by adjusting the distance between the sight and the rest. This will not improve arrow flight, but act to lessen the effect of an inconsistent bow hand.
Preparation
Start at a closer distance, like 10m, and get an initial position, before moving out to distance like 20 or 30m.
Place a target with an 80cm 6-ring World Archery face (or similar) at your selected distance. A blank white target with one vertical line is also recommended.
Ensure you have the correct tools available to move the rest in and out. No tools should be needed for the sight.
Technique
- Aim at the centre of the target.
- Twist the riser to point the pin/dot left or right to the side of the ten-ring.
- With your wrist remaining in this torqued position, aim the pin to the centre of the target.
- Take the shot & record the result.
- Adjust as necessary – Move the sight to get a rough setting, and the rest for fine adjustment:
- Sight: Move one position at a time
- Rest: Move in small increments, for example 1mm at a time.
Repeat until the torqued arrow and a normal arrow hit in the same place, or very close together. Ensure to test both left and right.
Notes
When shooting World Archery rounds, ensure you stay within the 6cm overdraw limit for the rest.
Some bows have a limitation at how much the rest can move, so it may be more practical to move the sight first and then use the rest to fine tune.
The optimum position seems to be around 22cm from the lens in the scope to the rest where it touches the arrow, thus it’s a good starting point.

Warning
Torque Tuning has an inherent danger as you’re putting twisting forces into the riser to simulate uneven pressure (“torquing the bow”) on the riser. Do not overdo this as you can derail the bow, and cause significant injury and damage, as well as void the warranty of your bow.
