About This Tool

The Zielscheibe Online Tool helps shooters and archers calculate accurate holdover adjustments for hitting targets at various distances. By inputting the target distance (in meters/yards), target size (diameter in cm/inches), and sight height (in cm/inches), the tool computes the exact angular holdover in MOA (Minutes of Angle) and MIL (Milliradians). This eliminates guesswork and improves accuracy for rifles, pistols, and bows. The tool includes a visual target representation and detailed results with conversion between measurement systems.
