bluetooth locator

Most trackers use Bluetooth (several list Bluetooth 5.4 LE) for local connections. Some devices combine Bluetooth with other locating systems — for example, ultra-wideband (UWB), GPS, Wi‑Fi and cellular — or use broader location networks to help find items beyond Bluetooth range.

Trackers use a few common battery options: built-in rechargeable lithium batteries (manufacturers quote runtimes of several months per charge), replaceable CR2032 coin cells (examples list around a year of life), and some devices that cite a non‑replaceable multi‑year battery.

Reported ranges vary by model and environment. Typical indoor ranges are around 10–20 meters, outdoor ranges commonly 20–50 meters, and some models report longer distances (for example up to about 250 ft / 76 m). Actual range depends on obstacles, interference and device antennas.

Both appear across products: some trackers offer wireless charging with a rechargeable lithium battery, while others use user‑replaceable coin cells (CR2032) or list a non‑replaceable multi‑year battery.

Package options include single units and multi‑packs; listings show single items and multi‑unit sets such as 4‑packs.

Descriptions highlight privacy and security measures such as anonymous, encrypted communications on the tracking network, secure sharing of location access with others, and some physical privacy features (for example a covered name card slot on luggage tags).
