Garmin Alpha TT25 GPS Tracking & Training Collar Base with Extended Battery
SKU:
Description
⚠️ REPLACEMENT / UPGRADE BASE ONLY - WILL NOT WORK OUT OF THE BOX.
This is the collar base unit only. It has NO GPS antenna and will not track at all until you add a Garmin GPS flex band, which is sold separately. The GPS antenna is built into the flex band - without one, this collar cannot locate your dog.
You must also purchase a GPS flex band:
➡️ Garmin TT25 Regular Flex Band (standard size, most dogs)
➡️ Garmin TT25 Short Flex Band (zero-length, smaller breeds)
🐕 The Garmin Alpha TT25 Collar Base with Extended Battery is a replacement or pack-expansion base that delivers up to 136 hours of runtime with dynamic tracking - same TT25 hardware, GPS and Galileo, 18 stim levels, 7-color LED, and 9-mile range as the standard TT25, with the expanded battery pack from the factory.
