Using the SpyX Tracker Tag is easy. First, you can either hide the tag in your bag or secretly place it on the person, pet, or thing you want to track. You don't need a smartphone or an app to use it. There are two modes. For Alarm Mode, set it up so that if someone takes your stuff, the tag will signal an alarm. In Tracking Mode, the tag will send out its location, and as you get closer, you can find what you're looking for. Remember, the range of the tag is up to 20 meters. Keep the tag away from water and extreme temperatures. If it's not working properly, you can try replacing the batteries. It's suitable for kids aged 6 and up, but adult supervision is recommended.
