Garmin TT(tm) 15X Dog Collar
Track and train: Garmin's TT 15X is a multi-purpose collar device for dogs. Use it with a Garmin Alpha handheld device to track and train your dog from up to nine miles away. The top-mounted, high-sensitivity GPS/GLONASS receiver updates your dog's location as often as every 2.5 seconds, so you always know where she is. The collar device also lets you train your dog with audible tone and vibration settings. Or, choose to administer momentary or continuous stimulation using the training key on your handheld Alpha device.
