The “Angle Cosine Indicator - Hunter,” ® (TM), (ACI-H), ® (TM), is a simple tool for hunters in mountainous terrain. It is utilized with ballistic targeting software, or to obtain the corrected for gravity distance to target.
The "Angle Cosine Indicator - Hunter", has the "Angle" numerals laser engraved onto the left side, and "Cosine" numerals laser engraved onto the right side.
The "Angle Cosine Indicator - Hunter," enables the Hunter to utilize ballistic targeting software or multiply the cosine numeral to the distance to target to obtain the corrected for gravity distance to target.
