Which one is right for you
- Choose Fi Series 3+ when
- You want months rather than days between charges — Fi states up to 3 months — and are happy to add a Fi membership, which is sold separately.
- Choose Tractive GPS Tracker when
- You want the lowest entry price and worldwide LTE coverage, and a $5–$8 monthly subscription is not a problem.
Watch out for: Tractive rates the tracker at up to 14 days per charge with Power Saving Zones and up to 6 days without. The Fi only fits Fi-affiliated collar bands, so you cannot keep your own collar, and both units are bulky on a small dog.
