Tips & Tricks

Best lighting

• All shots in the black: White light on a white background – place the target on a sheet of white paper or a bright table.
• Shots on the outside too: White light on a yellow background (e.g. yellow construction paper). This makes the white target field stand out well.
• Colored backgrounds (orange, red) are detected well too.
• Avoid: Direct sunlight with shadows, and backlight.

Photo technique

• Capture the whole strip: Every target must be visible, with no cut-off edges.
• Hold it straight: Don’t photograph at an angle.
• Avoid shadows: No fingers or hands on the target.
• Normal distance: You don’t need to get extremely close – a normal photo from 20–30 cm is enough.
• Background doesn’t matter: Ring Reader detects the target regardless of the background.
• Pinch-to-zoom: Use pinch-to-zoom on the target to place shots more precisely (review and manual entry pages).

Photographing Meyton printouts

• Photograph directly with the phone camera — don’t use screenshots or downloaded images.
• The image resolution must be at least 1000 pixels on the longest side.
• The entire printout should be visible in the image.
• Hold the phone parallel to the paper and avoid shadows.
• If the resolution is too low, the app shows a warning.

Understanding the MPI (Mean Point of Impact)

• The MPI shows where you hit on average.
• If your MPI is, say, top-right, you tend to aim top-right.
• Use the MPI to correct your sights: Adjust your sights toward the deviation.
• An MPI close to the center (a small distance) means your sights are well adjusted.

Understanding the Teiler

• 1 Teiler = 0.01 mm of deviation from the center.
• Smaller = better (0 Teiler = perfect center).
• The Teiler allows finer comparisons than the ring score alone.
• Example: two shots scoring 10.3 can still have different Teiler values – the one with the smaller Teiler sits closer to the center.

Using the group size (Trefferkreis)

• The group size (in mm) shows how consistently you shoot.
• Small group = even shots = good technique.
• Large group = heavy spread = check your technique (trigger, breathing, position).
