Fi Series 3+ GPS Dog Collar & Tracker (Membership Required)
⭐ Best ValueFi's Series 3+ is the most capable GPS dog collar we track: live cellular tracking with no range limit, escape alerts and safe zones, and a manufacturer-stated battery life of up to three months, far beyond what the rest of the category claims. Fi sells the collar as hardware only and states a Fi membership is required, chosen at activation; budget for it before buying.
