Yes, my daughter was babysitting when the mother of the child was frantic about the whereabouts of her son and my daughter. Gladly there's LAS GPS device to give me real time location and assure the mother that they are just in a nearby library because the car is parked on the lot. I didn't have to rely on cellphone locator which incidentally did not have signal in that room of the building! Standalone GPS units are essential in business. Thank you!
