The best portable Bluetooth trackers

Below we will show you how these small locators work, so we can choose the suitable model according to our needs.

How Bluetooth trackers work

The Bluetooth locators have the size and weight of a small key ring and have a button battery inside, useful for powering the small internal circuit equipped with Bluetooth, mini speaker box and (on the more expensive models) also a GPS detector.

Various operating modes are available, often selectable from the app or via the appropriate remote control:

  • Alarm: the simplest mode, allows you to detect the tracker simply by pressing a button on the remote control or on the app, so as to make it sound (revealing its position). To be able to play, the locator must be within the Bluetooth range (about 10-15 meters).
  • Fence: in this mode our locator will ring as soon as it loses the Bluetooth signal with our phone or remote control. Very useful to remind us immediately where we put the keys as soon as we leave or to check a suitcase when we are at the airport.
  • GPS position: the more advanced models integrate a GPS module, so they can be traced simply by opening the app and requesting the coordinates from the locator, who will show them on the map. Very useful for monitoring your wallet, valuables or as an emergency anti-theft device for cars (given its small size, it will go unnoticed even by the most careful thief).

They use a button battery as an energy source, easily replaceable when exhausted: with standard use, the button battery will last about 5 months on these devices. The work is completed with hooks, hooks and small laces with which we can fix the locator to the most disparate objects, so that we can monitor the objects we lose more easily.

Best locators with alarm

The simplest and cheapest are the locators with alarm, which work by means of a special remote control: each locator has a color or a number, which we can press on the remote control to start the acoustic warning. To turn off the acoustic warning we will have to press the button on the tracker: until we press it, it will continue to sound.
