On April 30, 2021, Apple began selling the original AirTag. As I noted in my review, the product did a great job of helping you to find a lost (or stolen) item. In the almost five years since then, the device has gotten even more useful. There are now lots of third-party accessories that work with an AirTag, making it easy to attach an AirTag to almost any type of item. Also, you can now share an AirTag’s location with third parties that you trust, such as an airline. Apple recently announced that, according to “a leading IT provider for airlines … using Share Item Location has reduced baggage delays by 26 percent and reduced incidences of ‘truly lost’ or unrecoverable luggage by 90 percent.”
Last week, Apple started selling the second-generation AirTag. It is just like the original AirTag, but a little better, for the same price. I purchased a set of four of the new AirTags and compared them to the original AirTags that I’ve been using for years. Sure enough, the new ones are a little better because they make it easier to find a lost device.
Louder
If I cannot find an item with an AirTag attached, the first thing that I do is open the Find My app on my iPhone and tap the specific AirTag in the Items tab. A map shows me where the AirTag is located. It is typically in the same place that I am located—such as in my house—so the next thing that I do is tap Play Sound and listen for the beep. That is usually enough for me to remember that, for example, I left my car keys in my jacket instead of in their usual location.
Apple says that the new AirTag uses an updated internal design that makes it 50% louder. Sure enough, in my tests, the speaker is louder, and that makes it a little easier to locate the AirTag.
Ben Lovejoy of 9to5Mac notes that, unlike the original AirTag, which has a chirp in the key of F, new AirTag chirps in the key of G, and you can hear the difference thanks to a video embedded in his post.
Improved Precision Finding
If playing a sound isn’t enough for me to locate an AirTag, the next thing that I do is tap the Find button, located right next to the Play Sound button, and then walk around. The Find My app will indicate when it can sense the AirTag and then, as you get closer, will display a huge arrow that points to the AirTag and says how far away it is.
For the original AirTag, that feature used Apple’s Ultra Wideband chip. For the new AirTag, the feature uses Apple’s second-generation Ultra Wideband chip, which Apple says will guide you to a lost AirTag frup up to 50% further away. In my tests, it definitely worked better.
I ran some tests in which I “hid” an old and a new AirTag right next to each other. In the same spot where my iPhone would tell me that it was still searching for a signal from my older AirTag, my iPhone was able to get a signal from the newer AirTag and tell me how far away it was.

As I moved around even more, eventually the old AirTag would appear to my iPhone with a weak connection, whereas in the same spot, the newer AirTag showed me an arrow to lead me to the exact location.

I saw this result over and over again. Not only was it easier to find the new AirTag from farther away, but it was also easier to find it when there were walls between me and the AirTag. The radio in the new AirTag is better.
To be fair, I don’t mean to imply that I never would have found the older AirTag. I just needed to spend more time walking around my house until I got close enough to get a signal. And of course, if I was far enough away, my iPhone wouldn’t sense either the old or the new AirTag. The point is simply that the new AirTag was easier and faster to find. That’s nice.
Better Bluetooth
What if the item with an AirTag is located far away from you? For example, what if I left an item in my office and I am now back in my house?
Each AirTag has a Bluetooth radio in it, which means that it can talk to other Bluetooth devices that are within the vicinity. The AirTag sends out a number that changes from time to time, and if another iPhone passes within Bluetooth range of that device, it will notice the AirTag’s number and notify Apple that a certain AirTag number was seen at a certain place and time. Because there are so many iPhones in the world, when you use the Find My app to search for an item, there is a good chance that you will learn of the location simply because an iPhone has passed by it. All of this happens without alerting the owner of the iPhone that happened to sense your lost device, so there are no privacy concerns.
The original AirTag could often be sensed by an iPhone that was 30 to 50 feet away. Apple says that the new AirTag uses “an upgraded Bluetooth chip expands the range at which items can be located.” Apple didn’t provide any specific quantification on how much better the new AirTag works. I haven’t yet been able to tell how much of a difference this makes, and I haven’t yet seen any published reports in which anyone else has been able to quantify the difference. Nevertheless, I presume that there will sometimes be circumstances in which the original AirTag could not be found but the new AirTag can be found because of the Bluetooth improvement.
Same size
When Brett Burney and I discussed the new AirTag during the latest episode of the In the News podcast, Brett said that it was unfortunate that Apple didn’t use this opportunity to change the shape or size of the AirTag. I see that Juli Clover of MacRumros said something similar in her review.
I disagree. By keeping the new AirTag the same size and shape, Apple ensured compatibility with all of the existing AirTag accessories. For example, I have been using a Belkin AirTag holder for my keys for almost five years, and it was simple to pop up my old AirTag and replace it with the new one. Suddenly, my keys became even easier to find.
I understand that sometimes it is nice to have something that works like an AirTag but is smaller. However, we already have that. Apple lets third parties make devices that work with Find My. For example, I use a thin device from Eufy that is about the size of a credit card in my wallet: the Eufy SmartTrack Card (my review), which is only $16.88 on Amazon.
Accordingly, I consider it an advantage that a new AirTag looks essentially the same as an original AirTag. In fact, the only way to tell them apart is to look at the back of the AirTag. If you see text in UPPER CASE, it is a second-generation AirTag.

Apple Watch Precision Finding
With an original AirTag and the new AirTag, you can use the Find Items app on an Apple Watch to get directions to the general location of the AirTag. However, that app does not support Precision Finding—the feature where you get an arrow pointing in the direction you should walk and the distance in feet.
With the new AirTag and an Apple Watch Series 9 or later or Apple Watch Ultra 2 or later, you can now use Precision Finding on an Apple Watch, making it easier to find an item when your iPhone is not around. However, Apple did not add this support to the Find Items app on the Apple Watch, which seems bizarre to me. Instead, you need to follow the steps on this page of the Apple website to add a specific item to the Control Center of the Apple Watch, one for each second-generation AirTag. Then, to use Precision Finding, you swipe up from the bottom of an Apple Watch screen and select the Control Center item for that specific AirTag.
This new feature works. Instead of an arrow, you see a circle with an arc indicating which direction to walk to get closer to the second-generation AirTag. And when you get to within a few feet, the display changes, similar to the way it works on an iPhone.

I’m glad that Apple added this feature, but I cannot figure out why they put it in the Control Center instead of the Find Items app on the Apple Watch, which is where it belongs. I’m sure that many owners of a new AirTag will have no idea that this new feature even exists. My hope is that a future update to the Find Items app on the Apple Watch will add support for this feature.
Conclusion
I don’t think that you need to rush out and replace all of your original AirTags. The first-generation AirTags will continue to work just fine. But if there is an item that is especially important to you, something for which it would be helpful if the item could be even easier to find, it is nice to have the option to use the improved second-generation AirTag. I’ve already made that change for my keys and my Tom Bihn bag that I take to work every day. However, I’m going to continue using my first-generation AirTags in situations in which I don’t need the latest and greatest. After purchasing these new AirTags, I now have four additional AirTags in my possession, so I can use AirTags for even more items.
