Designed to give a more realistic impression of engaging a human target during live-fire training. 'Bad Bob' is unique in that only a shot to the vital areas of the target's head, neck and chest will cause it to go down (only a shot to the head on HeadShot Bob). Depending on the scenario, the target can be adjusted by the turn of a screw to fall when shot by a .22 bullet or from repeated hits from a .45, simulating the resistance of a person on drugs or one wearing body armor. This feature now allows for interactive double-tap and failure-to-stop drills that cannot be duplicated by other target systems. Any type of pistol ammunition can be used, however hollow points will degrade the life span of foam faster. Shotguns may also be used, but a special steel plate is required for slugs. Always follow safe range procedures.
