Xero X1i Shooting High or "Bottoming Out" the Scope

The issue of shooting abnormally high or "bottoming out" the Xero® X1i crossbow scope is almost exclusive to faster shooting crossbows, 400 FPS (feet per second) or higher. 

Comparatively, shooting at a faster speed would equate to hitting higher at the 20 yard mark. This is true to the fact that top of the bolt's arch in flight will happen later along the flight path, but the overall curve will be flatter with a faster flight speed.

Understanding the Xero X1i Crossbow scope

Traditional crossbow scopes normally display the aim point in the middle of the scope's field of view. The Xero X1i scope differs from traditional scopes in that its field of view will place the 20 yard aim point higher up to allow for more potential range calibrations.

With Picatinny Rail mounting systems there may be some slight differences in design and specifications, but for faster shooting crossbows, mounting the Xero X1i scope further back on the rail will allow for a greater degree of available adjustments when it comes to ranges and aim points.

NOTE: A Software Update for the Xero X1i scope introduced the ability for the scope to inform the user of the potential to "bottom out" if certain adjustments are made for the 20 yard pin, based on the speed that was entered prior to the start of calibration.

Potential Solutions to Avoid Bottoming Out the Scope

• Ensure that the software on the Xero X1i scope is up to date. This will solve a vast majority of cases for this potential situation.
  • An option was added to the 20 yard calibration titled Out of Clicks.
• During calibration, the user will be asked to shoot the crossbow and will present the following options based on if the bolt hit the bullseye: Yes, No, or Out of Clicks.
• Clicking the Out of Clicks option will allow the aim point to be moved up in the display.
