The main differences between the Alpha TT15 and Alpha TT25 collars are battery life, design, and overall versatility. The TT25 is Garmin's latest track and train GPS collar, featuring updated software, improved bug fixes, and a more compact, lightweight body ideal for smaller dogs. While the TT15 offers a slightly longer battery life thanks to its larger battery pack, it lacks some flexibility in repairs—only the strap and antenna are replaceable. In contrast, the TT25 allows you to easily swap out the flex band, strap, and antennas, enhancing durability and customization. Additionally, the TT25 can be converted into a mini TT25, a feature not available on the TT15.
