BEFORE YOU BEGIN

Set up for your firearm and optic.

Select your firearm, optic, distance, target, and ammunition. The click value and distance give meaning to the adjustment shown for your group.

Your setup

Keep the assessment tied to the firearm and optic you are using.

Your target

Register a supported target with the camera, or use the photo-scoring option shown in the app.

Your group

Use a rested, supported group so the result is useful for checking your zero.

A CLEAR PATH TO CONFIRMATION

Measure. Adjust. Confirm.

01 / Measure the group

See the hits and the group center relative to your point of aim. Review horizontal and vertical offset together, rather than judging one hole.

01 / Measure the group

02 / Review the adjustment

See elevation and windage separately: which screw, how many clicks, and which turn direction. The app also shows an uncertainty estimate for the group.

02 / Review the adjustment

03 / Confirm the result

Fire another group after the adjustment. Review the new offset and the green confirmation when the result meets the app’s zero check.

03 / Confirm the result

OPTIC-SPECIFIC GUIDANCE

Know which way to turn.

Elevation and windage are shown with separate optic illustrations and turn-direction arrows.

If an arrow does not match your optic, the app’s Flip control lets you change that direction and remember it for that firearm. Check the markings on your optic before applying the adjustment.

The click counts in these screens belong to the recorded example. Your result depends on your own setup and shot group.
