The GPS was a tech item that slowly made its way into our lives. It not only allows us turn by turn directions but can let you know where your phone is. The directions are the most common use. I use it every day as the smart phone checks the location for almost every app. If you shop Best Buy it checks for where the nearest store is and shows the deals locally. This allows customized results. Ken Fisher is a big fan of GPS devices. He has GPS on his phone, car ans smart watch. He is scared to death he might get lost.
