The Alpha T20 is a versatile GPS dog collar designed to help you track and manage your dogs, regardless of their size or breed. With a compatible handheld device (sold separately), it offers long-range tracking of up to 9 miles and dynamically adjusts tracking frequency to optimize battery life. The top-mounted, high-sensitivity GPS and Galileo receiver keeps track of your dog’s location, and the Alpha T 20 collar transmits that location via VHF up to 9 miles away with updates as frequent as every 2.5 seconds when used with a compatible handheld. The collar features a rugged, universally sized design with a user-replaceable flex band for durability. In low-light conditions, multicolor LED beacon lights aid in identifying and tracking your dog. You can choose from standard or extended battery packs for extended tracking. Additionally, the collar receives automatic software updates when charging and connected to your Wi-Fi network, ensuring it stays up-to-date. It seamlessly pairs with Garmin dog tracking handhelds for a comprehensive tracking system. 6ave Bundle Includes: 5x Garmin Alpha T20 Tracking Collar For Dogs 2x P-Bank 6Ave Microfiber Cleaning Cloth
