The In-Reach Child Tracker is an easy way to put a homing device on your kid without the unpleasantness of surgical tracking device implants and things of that nature. After all, why should you be expected to keep an eye on your kid when you can just let him or her run wild and free and let technology keep track for you?

The tracker simply goes around your kid's ankle like a parole tracker and ensures that they stay within a boundary that you set. You have a receiver that lets you know just how far they are from you, so if they wander off you can go get the paddle and chase after them. Isn't modern parenting grand?
