Are you the type of person who wants to know how or where your loved ones are? If you are, then you can find out their whereabouts using GPS Tracking. LandAirSea Systems, Inc. offers different tracking devices for your specific use, like if you want to track specific persons, or if you intend to keep track of your vehicle. You can actually place a tracking device on your vehicle, and if you don't want it to be visible, then you choose one that is small but has good magnetic ability that even when submerged in water it will still stay put and send signals. You can also actually keep track of your vehicle using Google Earth, something that some think might not be possible. Isn't that just great? I believe that right now they are being used not only by civilians but also by military/government agencies.
Personally, though, what's really awesome is the fact that it can even help in a murder investigation! I read about this case regarding a 12-year old girl who was supposedly ran over by George Ford in Chenango County. Since his wife has placed a tracking device on his vehicle, the police could then verify if what he said in his testimony was accurate, or not. Below is a YouTube post about the news, if you want to know more:
I believe that we can find some more practical use with similar tracking devices. But what's great is that they are definitely here to stay!
