Fi Series 3 Smart Pet Locator Collar: GPS tracking with multiple satellite systems
For the pet parent who worries when their dog dashes out the door or their cat hides in the yard, this smart GPS collar offers more than just location tracking—it’s your constant companion for peace of mind. With nationwide LTE-M coverage and multiple satellite systems, you get reliable updates every few minutes, so you’re never left guessing where your furry friend is. In Lost Dog Mode, the collar switches to live tracking, giving you minute-by-minute updates that let you act fast if they wander off.
Beyond security, the AI health monitoring tracks activity, rest, and habits like scratching or drinking, alerting you to changes that might need a vet’s attention. The geofencing feature lets you set safe zones around your home, sending an escape alert to your phone if your pet strays. Lightweight and waterproof, it fits snugly on small pets, and the long battery life means fewer charges. Use it with the app to join community challenges or share locations with friends, turning safety into a shared effort.
