The new AirTag (2nd gen) 4-pack sold out quickly after launch and has been out of stock for weeks. It came back this Monday for Prime Day, and Amazon dropped it to $89, off its $99 list price and at its all-time low on Amazon. This deal is open to all Amazon customers with no Prime membership required, and at $89 for four tags the math runs considerably better than buying singles at $29 each.

50% louder speaker, upgraded Ultra Wideband, 1.5x Precision Finding range

The second-generation AirTag brings three meaningful hardware upgrades over the original. The speaker is 50% louder with a new distinctive chime that makes it easier to locate an AirTag by sound in bags, between couch cushions, or in a cluttered room where visual searching would take considerably longer. The upgraded Ultra Wideband and Bluetooth chips extend the Precision Finding range by up to 1.5 times compared to the previous generation, which increases the distance at which the directional arrow and distance readout appear on an iPhone. Precision Finding now also works on Apple Watch Series 9 and later, not just iPhone, adding a wrist-based navigation option for finding tagged items.

Share Item Location is a new feature that lets you temporarily grant location access to trusted contacts, third parties, or over 50 airline partners if a tagged bag goes missing in transit. That last use case is the one frequent travelers have wanted since the original AirTag launched: a way to share the location of a lost bag with an airline’s baggage team without handing over full Find My access to a personal device.
