Fi New Series 3+ Smart Dog Collar - GPS Tracker & Fitness Monitor

In this review the Fi New Series 3+ Smart Dog Collar is evaluated for dog owners who want reliable real-time location and meaningful health insights in one rugged device. The biggest reason to buy is its improved GPS performance that delivers nationwide tracking and instant escape alerts, making it easier to find a loose dog quickly. The collar also doubles as an activity and fitness monitor with AI-powered health insights, so owners who care about both safety and daily wellbeing will find this model particularly useful.

Key Features

• Improved GPS: 2x improved GPS performance gives faster, more reliable real-time location updates across the country so owners can track a roaming dog without range limits.
• Instant escape alerts: Lost Dog Mode and escape alerts notify owners immediately if the dog leaves a safe zone, helping shorten search time during an escape.
• Health and activity tracking: The collar monitors activity, rest, barking, scratching and eating to deliver AI powered health insights and a clearer view of daily wellbeing.
• Durable and waterproof: IP68 waterproofing and a 400 lb tug resistance make the collar adventure ready for wet conditions and active dogs.
• Long battery life: Up to 3 months of battery life reduces the need for frequent charging during regular use and longer outings.
• Integrated care tools: Stores vet records, integrates with Apple Watch, and includes an AI Companion for personalized care tips and reminders.

Who It's For

The Series 3+ is best for active dog owners, hikers, and families with escape-prone dogs who need nationwide GPS tracking and quick alerts. It is also suited to owners who want more than location data; the health monitoring features provide useful context for vets and everyday care.

Owners who prefer a simple passive collar without subscriptions or those who need specialized training stimulation devices should look elsewhere. This product is focused on tracking, health insights, and durability rather than remote training corrections.
