The Fi Collar Series 2 offers several improvements over the Series 1, including enhanced GPS accuracy and a more robust build with improved waterproofing. The Series 2 also features a longer battery life and a stronger LTE signal for better connectivity. For our compatible collars however, they use the same end links (connection points). So if you have a Series 1, you can select series 2 at checkout.
