North Shore Rescue in B.C. believes it’s the first rescue team in Canada to use a helicopter-mounted cell tower to trace a person’s location. The team uses something called a LifeSeeker unit attached to their helicopter that can pick up a lost person’s cell signal in a place without any other cell towers. This is how a regular phone tower tracking ping works, but in this case, it’s not a standard cell tower. Image credit: North Shore RescueSource: North Shore Rescue
