Description: Fi's smart collar has become one of the most recognized GPS trackers in the pet tech space, built around cellular-grade live tracking rather than short-range Bluetooth. <cite index="6-1">It uses an LTE-M cellular network to display real-time location across the US, Canada, and Mexico</cite>, so it keeps working well outside Bluetooth range in a way AirTag-style trackers cannot. The collar also runs AI-powered behavior detection, distinguishing between walking, running, and vehicle travel, and logging that alongside sleep and activity data for longer-term health insight. Build quality skews rugged: <cite index="6-1">the housing carries an IP68/66K rating for saltwater exposure and is designed to resist over 500 pounds of pulling and chewing force</cite>. Battery life is a standout feature, with <cite index="6-1">a single charge on the included wireless base lasting up to three months</cite> under typical use. As with all LTE trackers, live tracking requires an active membership on top of the hardware cost, and reviewers note that geofence alerts, while fast, are not instantaneous — typically arriving within about a minute of a boundary crossing.
