What to put a Bluetooth tracker on: a UK checklist

Deciding what to put a Bluetooth tracker on is mostly a question of which things you have already lost, not which things cost the most. This is a ranked checklist for a typical UK household, what each tag realistically saves you, and the five categories that are not worth a tag at all.

Which single item should get the first tag?

Your keys, unless you genuinely never lose them.

Keys are small, dark, carried daily and set down absent-mindedly. They also have the highest cost of failure of any everyday item: a lockout call-out, replacement fobs, and in a rented flat a conversation with a letting agent. A key ring comes in the box, so this is a ten-second fit.

The exception is the household where keys live on a hook and never move. In that case, skip to the bag.

Which items give the best return, in order?

Rank by how often you lose something, then by what replacing it costs.

Which household items surprise people?

The ones that vanish indoors rather than the ones that get stolen.

A remote control, a hearing aid case, a pair of reading glasses in their case, a child's water bottle, a cool bag, an umbrella, a set of allotment shed keys, a pet's lead. None of these are valuable. All of them cost twenty minutes and a raised voice when they go missing, and the tag's 80–100 dB speaker is what solves them — you are not looking at a map, you are following a noise.

The unglamorous truth about tags is that ringing them indoors is the feature people use weekly, and the map is the feature they use twice a year.

Which items should you not tag?

Anything that gets washed, anything that is not yours, and anything worth less than the tag.

1. Clothing that goes through a hot wash. The case is IP67, which covers rain and a puddle, not a 60-degree cycle.
2. Another adult's belongings, without asking. Covered in our guide to using a tracker lawfully.
3. A person or a pet that roams. No GPS, no SIM. A different product entirely.
4. Anything sealed inside metal. A steel toolbox or a metal flight case blocks the signal that the whole system depends on.
5. Items you lend out routinely. A tag that travels legitimately produces alerts and confusion instead of information.

How many tags does a household actually need?

Two to four for most homes, and the count is driven by people rather than by objects.

One adult who loses keys: two tags, keys and bag. A couple: three or four, since the second set of keys is as likely to go missing as the first. A family with teenagers: four or more, because coats and PE bags are where the losses concentrate, and items can be shared in Find My from iOS 17 onwards so everybody can ring everybody else's.

Buy them together. The commonest mistake is buying one, solving the keys, and then paying single-unit prices later for the bag.

Which specification numbers matter when choosing?

Range, loudness, battery type and platform — in that order.

Ring range up to 60 m covers a house and a front garden. A speaker at 80–100 dB carries through a cushion and a closed drawer. A replaceable CR2032 avoids throwing the tag away every couple of years. And the platform is the one that disqualifies people: these tags need Apple hardware carrying iOS 14.5 upwards, with nothing at all for Android owners.

How Beacon Tag covers a household checklist

A Beacon Tag ships two to a box with two key rings, which maps onto the first two rows of the table above without a second order. The body runs to 36.3 mm on each side, 9 mm from front to back and roughly 10 g, so it hangs on keys without weighing them and hides behind a bag lining without showing.

Ringing it from Apple Find My gives 80–100 dB, which is the function that pays for itself in the first fortnight. Past Bluetooth's 60 m, positions come from passing Apple devices, each report encrypted so that nobody else can read it. The IP67 case handles rain, a spilled bottle and a bag left on wet grass. The CR2032 cell lasts up to two years and any supermarket sells a replacement.

Stock is held in the UK with free delivery at any order size and 30 days to send it back, and the whole box is under £15.

Order a two-pack and start with the keys.
