Compared to your kid, Houdini was an amateur. If you avoid crowds and frequent fenced-in playgrounds for fear of losing your little one to the Big Wide World, we’ve got good news. From GPS-enabled smartwatches to innovative child leashes (no judgment here!), there’s a whole range of great gadgets and apps designed to stop little escape artists from disappearing—and how to find them if they do. Flip through the slideshow below to see our top picks.

Walkie Talkies

Breaker, breaker! Keep your crew connected the old-school way. Your kids will feel like secret agents, and you’ll feel like you can reach them on their own terms. Not sure which device to choose? This one gets rave reviews by users, and it’s got a reported range of nearly two miles. Plus, its smaller size and few buttons makes it a cinch for kids to operate.

Insider Tip: Stay away from toy walkie-talkies; most brands don’t have a very far range and don’t last very long.

Best for ages: 5+

Available at amazon.com for $27.99.
