As my son gets older, he'll be heading off to school and participating in after-school activities like little league or, better still, computer club. My wife and I wouldn't want to give him a smartphone in elementary school, but we would feel a lot better if we could know where he was at all times.

The Amber Alert GPS V3 is small enough to fit in even a tiny pocket while tracking your child's location both indoors and outdoors, anywhere in the world. Amber Alert's management software allows parents to set geofencing zones in locations where the child should be so they can receive email or text alerts when the child enters or leaves a zone.

The device features an SOS button the child can hit in an emergency and the ability to conduct 2-way calls between parent and child. Amber Alert's service, which costs $14.99 to $24.99 a month, is also integrated with the National Sex Offender Registry to alert you when your kid is within 500 feet of an offender's home.
