Apple AirTag (2nd generation) – Single Pack A2937

Product Name

Apple AirTag (2nd generation) – Single Pack

Product Overview

Apple AirTag (2nd generation) is a compact wireless item tracker designed for locating personal belongings through the Find My network. Introduced in 2026, the second-generation model retains the circular dimensions of the original AirTag while updating its wireless hardware, speaker system, and Precision Finding capabilities. The B0GJTFXNRX configuration contains one AirTag.

The tracker communicates through Bluetooth for proximity detection and includes Apple’s second-generation Ultra Wideband chip for compatible Precision Finding functions. When a tagged item is outside direct Bluetooth range, nearby devices participating in the Find My network can anonymously and securely relay its approximate location. NFC is also built in so a person who finds an AirTag can access Lost Mode information with a compatible NFC-capable device.

The second-generation version has a louder built-in speaker and an expanded Precision Finding range compared with the original generation. It uses a user-replaceable CR2032 coin-cell battery rather than a rechargeable internal battery. The enclosure is rated IP67 for splash, water, and dust resistance under specified laboratory conditions. AirTag is designed for tracking personal objects rather than people or pets and includes features intended to discourage unwanted tracking.

Technical Specifications

Find My Operation

AirTag uses Apple’s Find My system rather than an independent cellular or GPS connection. Nearby Find My network devices can detect the Bluetooth signal transmitted by a separated AirTag and relay an encrypted approximate location for the owner to view.

AirTag does not require its own cellular subscription. Location reporting outside direct range depends on nearby compatible devices participating in the Find My network, so update frequency can vary with location, device density, physical obstructions, and other environmental conditions.

Precision Finding

Precision Finding combines Ultra Wideband technology with compatible Apple devices to provide more detailed nearby-location guidance. Supported devices can display direction and distance information and provide visual, audio, and haptic guidance while searching for the AirTag.

The second-generation AirTag provides an expanded Precision Finding range compared with the original model. Apple documents a range improvement of up to approximately 50 percent under supported conditions. Walls, furniture, building materials, interference, and device orientation can affect practical range.

Expanded Precision Finding requires compatible Ultra Wideband hardware. General Find My tracking remains a separate function from the more precise short-range directional experience.

Built-In Speaker

AirTag contains an internal speaker that can play an audible alert when requested through Find My. The second-generation design produces a louder alert than the original generation.

Apple documents the speaker as approximately 50 percent louder than the previous AirTag and states that it can be heard from up to twice as far away under its test conditions. Real-world audibility varies with walls, bags, upholstery, ambient noise, and the way the tracker is enclosed.

Lost Mode and NFC

AirTag can be marked as lost through Find My. When another device in the Find My network detects the tracker, its owner can receive updated location information.

A compatible NFC-equipped smartphone can also read an AirTag in Lost Mode. This allows a finder to access information that the owner has chosen to make available for recovery of the lost item.

Privacy and Unwanted Tracking Protections

AirTag does not store a continuous location history on the physical tracker. Find My network communications use encryption intended to prevent participating devices from learning the identity of the AirTag owner.

The product also incorporates unwanted-tracking safeguards. Supported devices can alert people when an unfamiliar compatible tracker appears to be moving with them, and AirTag includes audible behavior intended to help identify a separated tracker.

These protections do not make covert tracking acceptable. AirTag is designed to locate personal possessions rather than monitor people without their knowledge or consent.

Product History

The original AirTag was introduced in 2021 as Apple’s first dedicated Find My item tracker. It established the circular form factor, CR2032 battery system, Bluetooth connectivity, Ultra Wideband-based Precision Finding, NFC interaction, and Find My network integration used by the product family.

Apple introduced the second-generation AirTag on January 26, 2026. The revision maintained the original dimensions so existing holders and accessories could continue to fit while updating internal wireless and acoustic hardware.

Major documented changes include Apple’s second-generation Ultra Wideband chip, an upgraded Bluetooth system, extended Precision Finding range, a redesigned louder speaker system, and Precision Finding support through compatible Apple Watch models. The second-generation model is identified by hardware model number A2937.

Buying Considerations

Apple Ecosystem

AirTag is closely integrated with Find My and compatible Apple devices. Users whose primary mobile devices are outside the Apple ecosystem do not receive the same setup and tracking capabilities.

Precision Finding Hardware

Not every compatible Apple device provides the same Ultra Wideband functions. Users specifically interested in the expanded Precision Finding capability should distinguish general AirTag compatibility from Precision Finding hardware support.

No Integrated Attachment Hole

The circular AirTag enclosure does not contain a built-in key-ring opening. Attaching it externally to keys, luggage, or equipment generally requires a separate holder or loop.

Thickness

The round 8 mm-thick form factor may create a noticeable bulge in a thin wallet. Card-shaped Find My accessories use a different physical design for that use case.

Replaceable Battery

AirTag uses a disposable CR2032 coin-cell battery rather than an integrated rechargeable battery. The design allows battery replacement without replacing the tracker itself.

Find My Network Dependency

Long-distance location reporting depends on nearby participating Find My network devices. An AirTag in an isolated area may therefore provide less frequent location updates than one in a populated environment.

Water Resistance

The IP67 rating provides limited environmental protection but does not make the tracker permanently waterproof. Physical damage and normal aging can reduce resistance.

Generation Identification

The original and second-generation AirTags have nearly identical dimensions. Model number A2937 is a useful identifier when confirming that a tracker is the second-generation version.
