The Angle Cosine Indicator (ACI) is an indispensable sniper tool for long distance precision shots when ai- ming 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 ERATAC® 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 Mil-Spec. version is waterproof for 35 min. and 1 meter depth of water.
The position of the elevation turret remains always visible because of the lateral bubble level.
