This locator is universal for Android and Apple ISO System. Is there a distance limit? No distance restrictions, globally available, as long as there are any Apple devices within 10-50 meters nearby, the equipment can be fixed in place. Is it real-time? When there are Apple devices nearby, it can achieve the effect of near real-time positioning. Moreover, the more Apple devices there are, the more accurate the positioning will be. If there are no Apple devices around, positioning will not be possible until Apple devices appear nearby (there will be an interval of 5 to 15 minutes for location updates). What is the working principle? The device will send out a secure Bluetooth signal every two seconds, allowing nearby Apple devices (mobile for phones, Computer, for ipad, etc.) to receive and upload to Apple iCloud as a Service to generate master location data. Only the owner of the locator can retrieve location data. So there are multiple nearby Apple devices, the faster the update, the more accurate it is. Which places are more suitable for use? It is generally more suitable in busy urban areas or places with more people using Apple devices.Remote areas or places with fewer people using Apple devices are not suitable.Please decide whether to purchase based on your own situation.
