Whenever you are considering using GPS tracking, make sure you understand the local laws. The Supreme Court has ruled that law enforcement needs a warrant to use a GPS tracking device. While this does not directly
Texas law is clear under penal code chapter 16 that it is illegal to install a tracking device on a car without the owner's permission. This also applies to private investigators who need written consent of the owner to install the device.
So, in a nutshell, you (or someone you hire) can put a tracker on your own car - but not on anyone else's car.
Pros: It makes it very easy to locate a vehicle 24/7. Some devices have monthly service charges that can quickly add up to big bucks.
Cons: Don't become one by breaking the law. In a more practical sense if you are being legal - you need to be aware of battery life and placement of the device. It has to be able to access satellites to be effective. Simply sticking it on the bottom of the vehicle with a magnet may not work. You need to test out the device in various vehicle locations beforehand. Every tracker is different - make sure you have an idea of what the battery life is likely to be on each setting.
Remember that whatever you do - stay safe!
