Precision Finding vs Bluetooth: what you actually lose

What Precision Finding actually is

Ultra Wideband is a short-range radio that measures the time a pulse takes to travel between two chips, which lets an iPhone work out both distance and direction to a tag rather than just signal strength. Apple has shipped UWB in iPhones since the iPhone 11 and in AirTag since 2021. The second-generation AirTag, launched on 26 January 2026, carries a newer UWB chip that begins guiding you from up to 50 per cent farther away than before.

Two constraints matter and are rarely mentioned in the same breath as the feature:

• Both ends need the chip. An iPhone SE, or any handset older than the iPhone 11, gets no arrow at all regardless of which tag you buy.
• It is a close-quarters tool. Even with the improved range, Precision Finding takes over somewhere in the region of a room, not a postcode. Getting to the room is still the map's job.

What you use instead without it

Every Find My tag, Apple's included, falls back on the same two mechanisms when UWB is not available, and for a tag without UWB those two mechanisms are simply the whole toolkit.

The map. The Find My network reports the tag's last confirmed position from whatever Apple devices passed it. That is what tells you the bag is in the office and not on the train.

The alarm. Play Sound triggers the tag's speaker over Bluetooth. This is the tool that finds the item once you are in the right room, and it is genuinely good at it, because your ears do the direction-finding an arrow would otherwise do.

The lost capability, precisely stated, is this: a visual bearing during the final ten to thirty metres. Not location. Not range. Not alerts. A bearing, at the end.

Five realistic scenarios

Keys under a coat in the hall. Alarm wins outright. You will hear it through the fabric before an arrow has finished orienting itself.

Rucksack somewhere in a four-bedroom house. Alarm again, comfortably. Ring it from the landing and follow the noise.

Suitcase on an airport carousel. Map first, is it even in this country? Then the arrow is genuinely nice, though a loud chirp in a hall full of identical black cases is nearly as effective.

Wallet dropped in long grass at a festival. This is the arrow's best case. Sound is swallowed by crowds and grass, the map places you within a few metres, and a bearing saves you a slow spiral search. If your losses look like this, buy the UWB tag.

Camera bag left in a taxi. Neither helps in the moment. What helps is Lost Mode contact details and the last sighting on the map. UWB is irrelevant.

The pattern

The arrow earns its keep where the item is outdoors, in a large or noisy space, and cannot be heard. It is close to worthless where the item is indoors, within earshot, and hidden by clutter, which describes the overwhelming majority of everyday losses.

The trade nobody puts on the box

There is a second-order effect worth being blunt about. Precision Finding is per tag, so its cost scales with the number of things you tag. Most people who buy one premium tag put it on their keys and stop. They then lose the suitcase, the camera bag or the laptop sleeve, none of which had a tag on it at all, and no arrow can find a tag that was never bought.

Coverage beats precision more often than it loses to it. A house where six things carry a plain Bluetooth tag is better protected than a house where one item carries the very best one.

How Orbit Tag helps

Orbit Tag carries no Ultra Wideband chip and offers no Precision Finding. We would rather put that in a heading than let anyone discover it after delivery. There is no arrow and no distance readout; what there is, is the map and the noise, the pair of tools described further up this page.

Both are specified properly rather than hinted at. The alarm sits between 80 and 100 dB, which is genuinely loud, enough to carry through a cushion, a coat pocket or a stuffed rucksack, and Play Sound reaches it over Bluetooth to a range of 60 m. Beyond that, the network keeps the most recent confirmed position current worldwide, using Apple's relays and Apple's end-to-end encryption, because this is a certified accessory rather than an own-app gadget.

Around that sit the details that decide whether a tracker is even attached when something goes missing: a ring hole through the case with two rings supplied, IP67 sealing, 9 mm of thickness, a CR2032 rated at roughly two years that you replace yourself, plus separation warnings, Lost Mode, lending to relatives from iOS 17 upward, and Apple's unwanted-tracking alerts. iOS 14.5 upward is the requirement; Android owners cannot use it at all.

Two trackers per box, under £15 a box, which is the coverage argument in a single line. see the tracker and what it includes.
