Why I Use Apple AirTags to Track Everything From My Luggage to My Car

I have come to rely on Apple’s handy trackers to keep tabs on my most important things, and right now you can stock up with a deal on four-packs.

Not long ago, as I waited at baggage claim after a trip to Paris, I became increasingly nervous as bag after bag dropped onto the carousel, none of them mine. I knew there was no need to panic, though. Back at Charles de Gaulle airport, I had dropped a sophisticated little tracking device into my trusty rolling suitcase before handing it over and heading to my gate. So, I pulled out my iPhone and, with just a few taps, I could see that my bag had never left the City of Light. (Merde!)

Over the years, I’ve come to depend on Apple’s AirTags to keep track of many types of easy-to-lose valuables. They’re not just good for luggage. I also use them to track wallets, bikes, keys and even my car. I tell everyone who will listen that you can never have too many of these handy devices. That’s why I think it’s worth taking advantage of the current deal at Amazon that slashes the price of a four-pack of AirTags down to $75.

Here’s how the Apple AirTag (like the one that was in my suitcase on that fateful trip) works. It uses an ingenious method of tracking itself, detecting its location from nearby iPhones and using them to anonymously piggyback the coordinates to a secure server where I could look it up on my iPhone. Until just a few years ago, this would have seemed like a scene straight out of a spy movie.

Instead of wondering if my belongings were stuck on an abandoned luggage cart or strewn across the tarmac, I could see in almost real time that my suitcase was still chilling at Charles de Gaulle airport in Paris. I was able to calmly tell the airline my bag didn’t make the flight, and it made arrangements to have it delivered to me a few days later.

Apple AirTags are all about peace of mind

By itself, an AirTag isn’t much. A smooth, round, 1.26-inch puck that looks like a glossy white breath mint, it sinks to the bottom of a bag or dangles from a key chain (with a compatible key ring, sold separately). It’s meant to disappear.

Activating the AirTag was a simple process of pairing with my iPhone. And then, because it obviously doesn’t really do anything out of the box, I forgot about it.

But the next time I couldn’t find my keys? Sorcery. My iPhone didn’t just tell me they were somewhere nearby — it walked me directly to them, thanks to the AirTag’s built-in Ultra Wideband chip. Suddenly, all that time I’d spent retracing my steps and overturning couch cushions in the past felt like ancient history.

Now I have AirTags in or attached to every significant item I’d want to keep track of: My everyday laptop bag, my camera backpack, the suitcase I use most when traveling, my key chain, my car and a smaller sling bag I take on walks. I can pull up the Find My app on any of my Apple devices (or sign in to iCloud on any web browser) and see where my items are and the last time the AirTags registered their locations.

AirTags aren’t just for my everyday items. People I know in the movie business tell me that AirTags are tossed into nearly every bag and Pelican crate, not solely to ensure that the valuable equipment inside doesn’t walk away but also to quickly differentiate equipment amid similar-looking containers. Some of my friends also attach AirTags to their pets’ collars (though experts say there are better ways to track your pets).

AirTags are also useful for things that you want to keep close by

Being able to detect my luggage a continent away provided a sense of relief, to be sure. But at the local level, my AirTags will also trigger an alert when I get too far away from them. For example, if I accidentally forget my camera bag in the car when I stop somewhere for lunch, a Find My notification appears telling me I’ve left it behind. It works the same for newer AirPods models as well.

Sharing is now a big part of AirTag tracking

My family has two cars, and I wanted to be able to track them both. But it used to be inconvenient to pair the AirTag in the car my wife drives to her iPhone (and the one in my car to my iPhone).

To guard against unwanted tracking, an AirTag will notify nearby iPhones of its existence, so whenever I drove my wife’s car without her in it, I got a notification that an AirTag was traveling with me. (If the owner is near the AirTag, the alert does not appear.)

However, ever since the release of iOS 17, AirTags are shareable, which solves this problem. I shared my AirTag with my wife, and she with me, so regardless of which car I’m driving, I can find it more easily in a crowded parking lot without getting constant, unnecessary alerts.

A more recent feature to AirTags that arrived with iOS 18.2 is the ability to temporarily share an AirTag’s location with someone I trust. In my luggage example above, if the suitcase was in the airport with me, but the airport’s staff hadn’t yet been able to locate it (not uncommon during peak travel times), I could share its location with an attendant who could quickly retrieve it from areas inaccessible to the public.

Apple AirTag specs

Diameter: 1.26 inches (31.9 mm)
Height: 0.31 inches (8 mm)
Weight: 0.39 ounces (11 g)
Splash, water and dust resistance: Rated IP67 (maximum depth of 1 meter up to 30 minutes)
Connectivity: Bluetooth 5.0
Battery: Replaceable CR2032 coin cell battery

The only minor annoyance about AirTags

An AirTag includes Bluetooth, the U1 Ultra Wideband chip and an NFC chip to share basic details when it’s in Lost Mode. That’s all powered by a CR2032 coin cell battery, which in my experience lasts roughly a year before I need to replace it.

I get notified when a battery is starting to get low, although there’s no gauge to see how much is left until it goes into the red. And it’s easy to change batteries. But my small fleet of AirTags means I need to swap multiple ones each year. I buy them in packs of 20 that I slowly work through.

AirTags also make great gifts

Apple AirTags consistently appear in our gift guides throughout the year because you can always find another use for one. They’re often reduced in price when sold in packs of four. And there’s an ever-growing ecosystem of ways to mount them, from sturdy vaults that adhere to a car to discrete fabric holders that will keep your favorite classic bomber jacket from flying away. Whenever I show someone how I use AirTags on a bag or keychain, I kind of wish I had a pocket full of AirTags to hand out because once someone sees how it works, they’re sold.

When will this deal expire?

We don’t know how long this deal will last. We see four-packs available at this discounted price pretty frequently throughout the year, but it could expire at any time without notice. I recommend placing your order while you can be sure to get this price, because I’m confident you’ll find new uses for them once you have a few.

TMR vs. Hall Effect Controllers: Battle of the Magnetic Sensing Tech

The magic of magnets tucked into your joysticks can put an end to drift. But which technology is superior?

Competitive gamers look for every advantage they can get, and that drive has spawned some of the zaniest gaming peripherals under the sun. There are plenty of hardware components that actually offer meaningful edges when implemented properly. Hall effect and TMR (tunnel magnetoresistance or tunneling magnetoresistance) sensors are two such technologies. Hall effect sensors have found their way into a wide variety of devices, including keyboards and gaming controllers, including some of our favorites like the GameSir Super Nova.

More recently, TMR sensors have started to appear in these devices as well. Is it a better technology for gaming? With multiple options vying for your lunch money, it’s worth understanding the differences to decide which is more worthy of living inside your next game controller or keyboard.

How Hall effect joysticks work

We’ve previously broken down the difference between Hall effect tech and traditional potentiometers in controller joysticks, but here’s a quick rundown on how Hall effect sensors work. A Hall effect joystick moves a magnet over a sensor circuit, and the magnetic field affects the circuit’s voltage. The sensor in the circuit measures these voltage shifts and maps them to controller inputs. Element14 has a lovely visual explanation of this effect here.

The advantage this tech has over potentiometer-based joysticks used in controllers for decades is that the magnet and sensor don’t need to make physical contact. There’s no rubbing action to slowly wear away and degrade the sensor. So, in theory, Hall effect joysticks should remain accurate for the long haul.

How TMR joysticks work

While TMR works differently, it’s a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet in the vicinity of the sensor. So far, it’s the same, right? Except with TMR, this shifting magnetic field changes the resistance in the sensor instead of the voltage.

There’s a useful demonstration of a sensor in action here. Just like Hall effect joysticks, TMR joysticks don’t rely on physical contact to register inputs and therefore won’t suffer the wear and drift that affects potentiometer-based joysticks.

Which is better, Hall effect or TMR?

There’s no hard and fast answer to which technology is better. After all, the actual implementation of the technology and the hardware it’s built into can be just as important, if not more so. Both technologies can provide accurate sensing, and neither requires physical contact with the sensing chip, so both can be used for precise controls that won’t encounter stick drift. That said, there are some potential advantages to TMR.

According to Coto Technology, who, in fairness, make TMR sensors, they can be more sensitive, allowing for either greater precision or the use of smaller magnets. Since the Hall effect is subtler, it relies on amplification and ultimately requires extra power. While power requirements vary from sensor to sensor, GameSir claims its TMR joysticks use about one-tenth the power of mainstream Hall effect joysticks. Cherry is another brand highlighting the lower power consumption of TMR sensors, albeit in the brand’s keyboard switches.

The greater precision is an opportunity for TMR joysticks to come out ahead, but that will depend more on the controller itself than the technology. Strange response curves, a big dead zone (which shouldn’t be needed), or low polling rates could prevent a perfectly good TMR sensor from beating a comparable Hall effect sensor in a better optimized controller.

The power savings will likely be the advantage most of us really feel. While it won’t matter for wired controllers, power savings can go a long way for wireless ones. Take the Razer Wolverine V3 Pro, for instance, a Hall effect controller offering 20 hours of battery life from a 4.5-watt-hour battery with support for a 1,000Hz polling rate on a wireless connection. Razer also offers the Wolverine V3 Pro 8K PC, a near-identical controller with the same battery offering TMR sensors. They claim the TMR version can go for 36 hours on a charge, though that’s presumably before cranking it up to an 8,000Hz polling rate — something Razer possibly left off the Hall effect model because of power usage.

The disadvantage of the TMR sensor would be its cost, but it appears that it’s negligible when factored into the entire price of a controller. Both versions of the aforementioned Razer controller are $199. Both 8BitDo and GameSir have managed to stick them into reasonably priced controllers like the 8BitDo Ultimate 2, GameSir G7 Pro and GameSir Cyclone 2.

So which wins?

It seems TMR joysticks have all the advantages of Hall effect joysticks and then some, bringing better power efficiency that can help in wireless applications. The one big downside might be price, but from what we’ve seen right now, that doesn’t seem to be much of an issue. You can even find both technologies in controllers that cost less than some potentiometer models, like the Xbox Elite Series 2 controller.

Caveats to consider

For all the hype, neither Hall effect nor TMR joysticks are perfect. One of their key selling points is that they won’t experience stick drift, but there are still elements of the joystick that can wear down. The ring around the joystick can lose its smoothness. The stick material can wear down (ever tried to use a controller with the rubber worn off its joystick? It’s not pleasant). The linkages that hold the joystick upright and the springs that keep it stiff can loosen, degrade and fill with dust. All of these can impact the continued use of the joystick, even if the Hall effect or TMR sensor itself is in perfect operating order.

So you might not get stick drift from a bad sensor, but you could get stick drift from a stick that simply doesn’t return to its original resting position. That’s when having a controller that’s serviceable or has swappable parts, like the PDP Victrix Pro BFG, could matter just as much as having one with Hall effect or TMR joysticks.
