GPS Maps

Technology has been so advance now compared to the previous decade. Did you know that gps maps are being used not only to track where a certain member of your family or employee is at the moment (usually with the mobile phone), or where a vehicle is at the moment (especially for those with trucking services), but even golf players are making use of it. Certain watches for golfers have several maps installed that they are able to know where they, as players, stand away from their ball. It surely is a great way to track where you are but could it also be a threat?
