Pick the Fi Series 3+ if you want a collar you charge every few weeks to months and you have AT&T LTE-M coverage where your dog roams. Pick the Tractive DOG 6 if you want the lower device price, coverage across AT&T, Verizon and T-Mobile, and health tracking, and don't mind charging every week or two.
The central trade-off
Battery. Fi states up to 3 months per charge; Tractive states up to 2 weeks. Both figures are best cases, and live tracking drains either one faster.
Coverage. Fi uses AT&T LTE-M. Tractive uses AT&T, Verizon and T-Mobile LTE in the US, which helps in areas where one carrier is weak.
What you're buying. Fi is a whole collar; Tractive clips to your own collar and adds activity, sleep and scratching data. Both require a plan, so compare plan prices over two or three years.
