What’s in the Box?
The Fi Series 3+ arrives in a sleek, eco-friendly box that’s easy to open—no scissors required! Inside, you’ll find the collar itself (in vibrant colors like Yellow or Blue), a USB charger, and a quick-start guide. At just 77 grams, it’s lightweight enough for daily wear without bugging your dog. My first thought? “This feels premium, not plasticky.”
Fit and Comfort Check
Available in sizes from X-Small to X-Large, it adjusts snugly with a durable buckle. Max’s Medium fit perfectly, and the soft material didn’t irritate his neck during long walks. Waterproof to boot, so no worries about puddle jumps or rainy romps.
| Size | Neck Girth (inches) | Best For |
|---|---|---|
| X-Small | 8-12 | Small breeds like Chihuahuas |
| Small | 11-15 | Pugs or Terriers |
| Medium | 14-20 | Beagles or Cocker Spaniels |
| Large | 18-26 | Retrievers |
| X-Large | 24-30 | Labs or Great Danes |
2. GPS Tracking: No More Hide-and-Seek Nightmares
Lightning-Fast Location Updates
The star feature? Its next-gen GPS with 2x better performance. Nationwide coverage means no dead zones in my suburban hikes. I tested it by “losing” Max in the park—location pinged in seconds, accurate to within 3 feet. Phew!
Virtual Fences and Escape Alerts
Set up custom safe zones via the app, and get instant alerts if your dog bolts. Lost Dog Mode kicks in with rapid updates, turning panic into quick reunions. It’s like an invisible leash for worrywarts like me.
3. Health and Behavior: Beyond Just Steps
AI-Powered Insights
This isn’t your basic pedometer. The Fi tracks activity, rest, barking, licking, scratching, eating, and drinking. Max’s data showed he was scratching more at night—turns out, allergies! Early catch that saved a vet trip.
Daily Wellness Snapshot
Daily reports are digestible, not overwhelming. See trends over weeks, like if playtime dips. It’s empowering, helping you tweak routines for a happier pup.
| Tracked Metric | What It Monitors | Why It Matters |
|---|---|---|
| Activity | Steps, distance, calories | Ensures exercise balance |
| Barking/Scratching | Frequency and patterns | Spots stress or health issues |
| Eating/Drinking | Habits and hydration | Prevents dehydration or overeating |
4. App and Integrations: Seamless Tech Magic
Apple Watch and iPhone Sync
Glance at Max’s location or activity right on your Apple Watch—super handy during runs. The app’s AI Companion answers queries like “Why is my dog restless?” with tailored tips. Plus, smart reminders for vaccines? Genius.
Vet Records at Your Fingertips
Upload docs digitally; the collar organizes and summarizes them. No more digging through papers—everything’s searchable and secure.
5. Battery Life and Practical Perks
All-Day Power
With a 285mAh battery, it lasts up to 3 months on a charge. Quick USB top-ups keep it hassle-free. In hot weather, it held up without overheating.
Durability in Action
Waterproof and chew-resistant (Max tried!), it’s built for rowdy dogs. Colors like Yellow pop on leashes, making it stylish too.
| Color Option | Availability | Vibe |
|---|---|---|
| Yellow | New Version | Fun and energetic |
| Blue | New & Old | Cool and calm |
| Gray | New & Old | Sleek and neutral |
| Pink | New | Playful for gals |

The Wins
Pros: Reliable GPS, insightful health data, easy app, long battery. It’s peace of mind in a collar, especially with the included 12-month membership.
