ERA-TAC ACI-Angle Cosine Indicator
[Code: T0941-0000]

ERA-TAC ACI-Angle Cosine Indicator
ERA-TAC ACI-Angle Cosine Indicator

The Angle Cosine Indicator (ACI) is an indispensable sniper tool for long distance precision shots when ai­ming up- or downhill. The ACI helps you to easily cal­culate and correct the gravity‘s effect on your bullet‘s trajectory.
The bubble level enables the shooter to understand if the gun is completely level. Our ERA-TAC-mount with ACI and bubble level can be easily attached to our UNIVERSAL-interface. It is not necessary to alter the position of the scope. The position of the ACI is such that the red needle is visible even when using a scope with the illumination control on the left side and while already aiming. The position of the elevation turret re­mains always visible because of the lateral bubble level.
 
How to use the ACI:
1. Measure the distance to target by your rangefinder or your scope‘s reticle
2. Aim at the target and read the number shown on the Angle Cosine Indicator; multiply the actual distance by the shown cosine number to get the adjusted distance for gravity.
 
Example:
target distance: 800 m
Cosine number shown on ACI while aiming at target: 0.87
adjusted distance to target: 800 x 0.87 = 696 m
