This StrikeGuard device pictured above is the actual equipment that detects lightning. It is located on the roof of the clubhouse on a tripod that stands about 36" tall. This equipment measures cloud to ground lightning strikes within a 20 mile radius of it. When lightning is detected within a 5 mile radius of the Club, the horns will sound alerting golfers to seek shelter.
