Apple AirTag (2nd generation)

Apple's second-generation AirTag, launched in January 2026, is the most reassuring gift you can give an iPhone-owning traveller: slip one into a checked bag and they can see roughly where it is almost anywhere in the world through Apple's Find My network. Apple says the new model's second-generation Ultra Wideband chip extends Precision Finding up to around 50% farther and makes the speaker 50% louder, and it keeps the IP67 water and dust rating plus a user-replaceable CR2032 battery that lasts over a year. Independent testers at CNN Underscored rate it the top luggage tracker for iPhone users thanks to the size and reliability of Apple's finder network. At an indicative £29 for a single or £99 for four, it is by far the cheapest pick here and works as a stocking filler or a set - just budget a pound or two for a keyring holder, as the disc has no hole.
