A new $40 gadget promises to help travelers detect hidden cameras in places like Airbnbs, offering peace of mind for those worried about privacy. Marketed as a simple, affordable solution, it scans for bugs and GPS trackers—because nobody wants to be secretly watched on vacation.

Editor’s Note: As short-term rentals boom, so do concerns about hidden surveillance. This gadget taps into growing unease about privacy in shared spaces, making it a timely (if slightly paranoid) purchase for cautious travelers. It’s not just about Airbnb—it’s a sign of how tech is both creating and solving modern trust issues.
