Dig a little deeper on the deal that Amazon’s currently offering on a 4-pack of 2nd-gen Apple AirTags and it looks even better. The first glance at the discount — $10 off the normal price — might not get you diving for your wallet. But when you look at the many ways an AirTag can save you from a lost-item crisis and see that they work out to just over $22 per unit, it’s a common-sense purchase waiting for your click.

A new Ultra Wideband chip and upgraded Bluetooth extend the Precision Finding distance of the newer-gen AirTags by up to 1.5 times compared to the original. Precision Finding is the feature that gives you actual directional arrows and distance readouts rather than just a general location ping, and for anyone who’s played Marco Polo with a Bluetooth tracker’s vague and hard to track ping, that alone makes this deal worthwhile.

Apple Watch Support

Another notable 2nd-gen addition is Apple Watch support for Precision Finding. That step-by-step directional feature used to only work on an iPhone. Now it works from your wrist as well, which solves the biggest issue with the original AirTag: What do you do when it’s your phone that’s missing? The speaker also got a big bump — it’s 50% louder with a new chime — so triggering an audible alert from your keys or wallet is more likely to actually cut through ambient noise.
