Sight in bow at 20 metres (yards) and at 60 metres (yards) Mark the two distances from your sight onto a strip of paper, then slide the strip along the chart until the two marks correspond to the distances on the chart,while keeping the strip parallel to the vertical lines. Where each distance line intersects the edge of the tape, place a pencil mark and note the distance then transfer these distances back to your sight then shoot these distances to check the accuracy of the marks. (Very little adjustment should be necessary). http://www.bowmenofskelmersdale.co.uk/sight_calibration.html
