What is the point for having the new 4 series ATN device, if the target is too far to shoot at responsibly? Well ABL is your answer. Mount it in minutes, to the front of your ATN Smart sight and turn your scope into any future hunter's dream. Control the ABL through your sight with a simple one button operation. Once ranged in on your target your POI (Point of Impact) is instantly adjusted and you are ready to make your shot. Just don't forget to keep those hands steady.
