The calculator has been designed with target shooting competitions in mind – the target size scale ranges from 4 – 40 inches and on the back side of the calculator are the exact measures of most common targets (IPSC ja IDPA).
For the distance measurement it is only necessary to align the MILs scale with actual target size scale and the distance to target can be seen from the Distance Window.
Size: the diameter of the calculator is 4,53 in (11,5 cm).
