The LabRadar accuracy will not be affected by other shots being fired into your radar beam. Part of the technology built into the system allows it to determine if the shot came from very near the radar unit or if it came in from another location. Since the radar tracking is only active for a fraction of a second it is nearly impossible for you to receive a velocity from another shooter nearby. Your unit also has an adjustment in it to “turn off” most gunshots that are nearby, yet allow your shot to operate the unit. In rare cases your unit may be triggered by someone elses muzzle blast. If this occurs, you can easily delete that shot from your data.
