Altering Entered Bow Speed on the Xero X1i After Calibration
When using Auto Calibrate, a stack of calibrated aim points out to 80 yards is generated based on the bow's speed and the Xero® X1i crossbow scope's ballistic algorithm. Auto-calibrated aim points should be validated for accuracy at 50 meters or 50 yards. It is especially important to validate your accuracy at the 50 yard mark if you enter the crossbow manufacturer's advertised speed.
NOTE: Speed readings from a chronograph should be used to get the most accurate calibrated aim points with the specific bolt you are using. If access to a chronograph is not available, the bow's advertised speed can be entered and auto-calibrated aim points can be adjusted manually to compensate. For steps to edit calibrated aim points, see - Editing Bolt Profiles and Adding Ranges for the Xero X1i Scope
NOTE: If you change your bow speed once you have manually created or edited any pins, you should verify the pins (including 20 and 50 yards/meters) are still set appropriately, and edit them if needed.
Editing Aim Points After Bow Speed Changes
If needed, aim point stacks can be edited individually after initial auto calibration through the scope's setup menu to achieve a greater level of accuracy.
- From the main menu, select PROFILE
- Select the active profile you wish to edit
- Select AIM POINTS
- Select an aim point to edit
- Select CALIBRATE
PROFILES also has an option to edit the entered value input in ENTER BOW SPEED from the initial calibration. However, doing so will alter the generated aim points on the profile and require that each aim point be re-validated and most likely re-calibrated to ensure accuracy.
TIP: Given the amount of time and effort going into editing and re-calibrating Aim Points after altering the entered Bow Speed on an existing Bolt Profile, following the steps in Creating a New Bolt Profile for the Xero X1i Scope would allow the user to start the auto-calibration process again and enter a new value for ENTER BOW SPEED for a new Profile.
