Troubleshooting
The point of impact moves between shots
There are several factors that can cause variations in the point of impact.
• Verify the screws that connect the riser mount to the riser are tightened to the maximum torque specification
of 6.7 N-m (60 lbf-in) and the mount is securely attached to the bow.
NOTE: Do not exceed the bow manufacturer's recommended torque values.
• Verify each adjustment knob lock screw on the mount is tightened to the maximum torque specification of
2.2 N-m (20 lbf-in).
• Verify you are using the correct arrow profile for the type of arrow in use.
• Range your shots consistently at full draw or at rest.
• Inspect your bow and confirm all of its components are in good working condition.
• Always use consistent form when shooting a bow. Variations in stance, grip pressure, and peep sight
placement can affect accuracy.
My device only displays fixed pins
When the batteries are low or do not meet the minimum power requirements for the laser rangefinder, the
device allows only fixed pin sighting.
• Verify the battery level of the batteries you have installed.
• Verify you are using AAA lithium batteries.
Tips for Consistent Ranging
If you are a target shooter, consistent ranging can help to increase your accuracy.
• Use the rangefinder consistently while you are using the same form (at full draw or at rest).
• Enable decimal precision (Pro Settings, page 16).
• Verify you are aiming the reticle at the target when you release the ranging trigger.
