FitBark GPS 2nd Gen matches Fi Mini at 16 g and supports on-board GPS, multi-network LTE-M, Wi-Fi, cell-tower assistance, and Bluetooth. It works for pets from 5 lb in four officially supported countries and has flexible long-term subscription pricing, but the battery claims vary dramatically by mode: the six-month figure is Bluetooth-only, while continuous live GPS is rated up to six hours.
