This ADI is calibrated in degrees and cosines give you an instant readout which can enter directly into a ballistic software program on your Pocket PC or use with a pre-printed angle drop chart to achieve high accurate shooting. The red needle moves with your rifle and displays a number that indicates the percentage that your rifle is off level. Multiply the indicated percentage by the target distance to easily calculate the adjusted distance for gravity. The bubble level which can be flipped to the side also allows you to have an additional indicator to achieve much higher accuracy.
