Where Tractive Leads
Tractive GPS Advantages
Global Coverage in 175+ Countries
Tractive operates on local LTE networks across 175+ countries with no roaming setup required. Travelers and owners near borders get consistent tracking coverage that Fi simply cannot match — Fi is restricted to the US.
Faster Live Tracking Updates
In LIVE mode, Tractive refreshes your dog’s location every 2–3 seconds. This makes a meaningful difference when a dog is actively escaping — you see movement in near real-time rather than waiting minutes between pings.
More Affordable Subscription
Tractive’s annual plan starts around $5/month per device, roughly half the cost of Fi’s annual subscription. For multi-dog households or cost-conscious owners, the savings add up quickly over time.
More Detailed Activity Data
Tractive tracks steps, active minutes, rest periods, and sleep quality — and compares your dog against similar breeds. The health insights go slightly deeper than Fi’s activity summary.
IP67 Waterproof — No Removal Needed
Rated IP67, the Tractive GPS DOG 4 handles submersion up to 1 meter for 30 minutes. It’s built for dogs that swim, splash, and play in the rain without any worry about water damage.
Where Fi Leads
Fi GPS Advantages
Exceptional Battery Life
The Fi Series 3 uses an ultra-efficient combination of GPS, LTE, and WiFi to deliver 3+ months of battery life in standard tracking mode. For owners who forget to charge devices, this is a significant practical advantage over Tractive’s 5–7 day cycle.
Built-In Smart Collar Design
Fi integrates the tracker directly into the collar band rather than attaching an external device. This creates a cleaner look, eliminates the risk of the tracker snagging or falling off, and works with any standard collar loop.
WiFi + LTE + GPS Trilateration
Fi uses all three positioning methods simultaneously: GPS satellites, LTE cell towers, and WiFi networks. In dense urban environments with strong WiFi signals, this can produce highly accurate indoor and near-home positioning.
IP68 Water Resistance
Fi’s IP68 rating exceeds Tractive’s IP67, allowing deeper submersion for longer durations. For dogs that spend significant time in water — retrievers, water dogs — this extra protection is worth noting.

Frequently Asked Questions
Is Tractive or Fi more accurate for GPS tracking?
Both use GPS and LTE for location. Tractive’s LIVE mode delivers updates every 2–3 seconds, making it more responsive during active tracking. Fi updates less frequently in standard mode but compensates with WiFi positioning near home. For escape situations where real-time movement matters, Tractive’s faster refresh is an advantage.
Which has better battery life — Tractive or Fi?
Fi wins on battery by a significant margin. The Fi Series 3 lasts 3+ months in standard mode. Tractive lasts 5–7 days in standard mode and around 2 days in LIVE mode. If charging frequently is inconvenient for your lifestyle, Fi is the stronger practical choice.
Can I use Fi GPS outside the United States?
No. Fi operates on US cellular networks only and does not support international tracking. If you travel abroad with your dog or live near an international border, Tractive’s 175+ country coverage makes it the only viable option between the two.
Which is cheaper — Tractive or Fi?
Tractive is significantly cheaper on subscription. Tractive’s annual plan starts around $5/month. Fi’s annual plan starts around $9.99/month — nearly double. Over two years, the difference amounts to roughly $120 in subscription savings with Tractive.
