This precision-machined aircraft-grade aluminum ADI takes the guesswork out of climbing and descending mountains.
This ADI is calibrated in degrees and cosines to give you an instant reading which can be entered directly into the ballistics software program on your pocket pc or used with a pre-printed angle drop chart to achieve highly accurate shots.
The red needle will move with your display a number showing how much your is on the level. Multiply the specified percent by the target distance to easily calculate the adjusted gravity distance.
The spirit level, which can be flipped to the side, also allows you to have additional reading to achieve much higher accuracy.
