This locator is compatible with Android and Apple iOS devices. Is there a distance limit? There are no distance restrictions, and the device is usable globally as long as there are Apple devices within 10-50 meters nearby to assist with positioning.Is it real-time? When Apple devices are in proximity, near real-time positioning can be achieved. The more Apple devices nearby, the more accurate the location becomes. If no Apple devices are present, positioning will not occur until one comes within range, which may result in location updates every 5 to 15 minutes.How does it work? The device emits a secure Bluetooth signal every two seconds. Nearby Apple devices (such as iPhones, iPads, or Mac computers) detect this signal and anonymously upload the data to iCloud, enabling location tracking. Only the owner of the locator can access the location information. More nearby Apple devices lead to faster updates and improved accuracy.Where is it most effective? This device works best in urban or high-traffic areas where many people use Apple devices. It may not perform well in remote or sparsely populated regions with few Apple users. Please consider your environment before purchasing.Why might positioning be inaccurate? Inaccuracies may occur if no Apple devices are nearby. Location data may take 5–15 minutes to update. Note that Bluetooth-based tracking is less precise than GPS but offers longer battery life without the need for constant charging or data plans.Key advantages: This Bluetooth tracker uses a replaceable button battery, providing up to one year of operation depending on usage. No subscription fees or additional costs are required. A CR1225 battery typically lasts 2–3 months under normal conditions.Color: Black Material: Plastic Package Contents: 1 x Locator Note: The package includes only the items listed above.
