The Biometric Object Analyzer (or BOA 3) is an optical attachment featured in Call of Duty: Black Ops III. This optic illuminates red when an enemy is in frame, or blue for a friendly. Active Camo users will be illuminated by the sight.
The BOA 3 also increases centerspeed by 10% making it optimal for guns with lower centerspeed. it also has a slightly higher zoom level compared to the Reflex sight and ELO sights.
