    The ACI lets you do some calculations directly, without using a PDA. Knowing only the degrees requires you to have an angle chart, PDA etc.

    AJ is right (unless your really good with numbers). The ACI will allow you to do some quick "on the fly" calculations. Cosign X MOA elevation for straight line distance= correct elevation dope(quick and dirty).
