These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.
Fi Series 3+ GPS Dog Collar and Tracker (FCB3), Size L
Medium and large dogs whose owner will keep a Fi membership running
The Series 3+ is an all-in-one cellular GPS collar with a stainless steel frame, IP68 rating, LED light and wireless charging. Fi states up to three months of battery life, which is unusually long for a cellular tracker. One month of membership is included and it renews after that to keep GPS service active, and part of the warranty Fi advertises is a membership benefit.
Published specifications

- Fi: up to 3 months battery life; wireless charging; charger and USB cable in box
- Fi: industrial stainless steel frame, stated to handle 500 lb of resistance
- Fi: IP68 and IP66K certified, claimed fresh and salt water to 50 m deep
- Fi: modular sizing XS to XL; this ASIN is size L in blue; built-in LED light
- Listing: model and part number FCB3; battery capacity 285 mAh; 2.72 oz
Strengths
- Fi states up to three months of battery, far longer than most cellular trackers
- Stainless frame, IP68 and IP66K rating and wireless charging suit heavy wear
- Escape Alerts, Lost Dog Mode and shared household access come with the app
Caveats
- GPS service stops unless the membership is renewed after the first month

Tractive DOG 6 XL GPS Pet Tracker (TG6XLC)
Dogs over 44 lb whose owner wants the longest interval between charges
The DOG 6 XL is Tractive's large-dog tracker: 3.3 by 1.9 by 0.8 inches, 2.5 ounces, rated for dogs above 44.1 pounds and collars up to 1.6 inches wide. Tractive states up to six weeks of battery when Power Saving Zones are in use, three times the standard DOG 6. It is a cellular device, so a paid plan is required, and the listing's own size field quotes the smaller model's dimensions.
Published specifications
- Tractive: recommended for dogs above 44.1 lb; fits collar widths up to 1.6 in
- Tractive: 3.3 x 1.9 x 0.8 in, 2.5 oz; the listing table quotes the smaller model
- Tractive: up to 6 weeks battery, stated with Power Saving Zones in use
- Tractive: 100% waterproof IP68; the listing field says only water resistant
- Tractive: LTE/4G Cat1bis, Bluetooth 5.0, WiFi; GPS, GLONASS, Galileo
- Tractive: requires Android 10.0+ or iOS 17.0+; built-in SIM needs a paid plan
Strengths
- Up to six weeks between charges, three times Tractive's standard dog tracker
- IP68 rating and a published 1.6 inch collar width limit you can measure against
- Cellular and GPS, so it reports position without relying on nearby phones
Caveats
- Tractive rates it only for dogs above 44.1 lb, so it rules out most breeds
- Amazon's size row quotes the smaller DOG 6 dimensions, not the XL's
- Listing says two-year warranty; Tractive's own terms supply products as is
