Archery Sight Mark will save you time by not having to sight your bow at every distance after changing arrows or making adjustments to your equipment.
Simply sight your bow at three known target distances and record the sight elevation for each of the three reference marks. These references provide the app with all the calibration data needed to develop a quadratic regression model that can predict sight elevations at other distances.

1. In most scenarios, the app will provide accurate sight elevations for all distances within the calibration range. Sight elevations for distances extending outside the calibration range are also calculated, but may be less reliable.
2. Be aware of parallax effects when measuring reference marks at close distances. DO NOT use a calibration reference of, say 10 metres, and expect the regression model to be accurate. The ideal reference distances are about 20m, 40m, and 70m for bows that can fling arrows faster than 200fps.
3. The sight profile can be influenced by many factors in your bow set up. To be safe, always operate your archery equipment in an appropriately controlled environment.
