The City of Delta B.C. is apparently the first community in Canada to employ so-called GPS darts to safely apprehend fleeing drivers. The trial program has seen eight Delta police cars equipped at $1,200 a vehicle by the Delta Police Foundation. The system is made and sold by a Virginia Beach, Virginia firm, StarChase Pursuit Management Technology and is said to provide a safe alternative to the dangerous practice of car chases. Officers launch a GPS dart from the front of their cruiser, it sticks to the rear of the escaping vehicle, police dispatch then monitors the fleeing vehicle and reports its location to nearby units when it is parked. The material online does not appear to state a range for the dart but logically line-of-sight would be required.
