PAJ's PET Finder 4G Mini is a true GPS tracker with its own European 4G SIM, Bluetooth-assisted indoor power saving, a 33.1 g body, and a 3 kg minimum dog weight. Its purchase includes more than two years of service and the official page provides unusually complete technical and media evidence, but it is the heaviest tracker in this lightweight ranking, continuous tracking lasts only one to two days, and it is not designed for U.S. cellular use.
