There are many personal tracking devices for parents to choose from when they are ready to use one to watch over their child and protect them from danger away from home. Of course not all of these devices use the same methods to track children and the difference many times will be reflected in the price. Some methods of tracking are more effective than others and parents should understand each one in order to pick the method that will work best for them. Of course when it comes to your child, price should not be the deciding factor, but effectiveness should be.

Two of the most popular methods of tracking involve GPS technology and E911 services and both are fairly effective at locating individuals. Both use triangulation for calculating location of the device but each uses different tools to do this.
GPS technology uses satellites in outer space to triangulate the location of the device which is the most accurate way to do this and will often give coordinates within fifteen feet of the actual location.

E911 devices use cell phone towers to triangulate the location in question and while somewhat effective it will only give an approximate location with the area of the closest towers. While effective it is not the most accurate method for parents who want the best.

Though these are not the only methods to track a child, for farther distance both are fairly effective as opposed to radio technology. While cell phones are handy for talking to children directly they are not an assurance that  a parent can locate them should an emergency arise. Many experts agree that nothing is even close to a GPS tracking device for accuracy and dependability despite their limitations when there is no clear line of site to the sky.
