How far can Bluetooth tags track?

Bluetooth tags have a direct range of about 30 to 40 meters. Beyond that, the location updates automatically when a compatible Android or iOS device passes nearby.

Is the tracker built into the accessory?

No — our accessories (bracelets, collars, mounts) are sold separately. The Bluetooth tag fits easily inside for a seamless, discreet integration.

How long does the battery last?

Bluetooth tags are low energy and typically last 8 to 12 months on a single battery. You’ll receive a notification when it’s time to replace it.
