Airtag + GPS.
A different breed.

Airtags use the proximity of iPhones to track objects. If your dog is not within 200ft from an iPhone, the Airtag system won’t be able to find them. Airtags do not have GPS or LTE to function independently. Without an iPhone around they can’t locate anything.

Up to 3 months on one charge

The Fi Series 3 is a record setting, power-efficient smart collar that you can put on your dog and forget about for weeks. Fi uses its proprietary algorithms to achieve this incredible battery life.
