An intuitive electronic bark correction device designed by Garmin using proven technology from Tri-Tronics, the leader in electronic dog training for more than 40 years. Using innovative bark identification technology powered by micro electro-mechanical acceleration sensors, the BarkLimiter series is able to distinguish between barking and other vocalizations. Also exclusive to the new BarkLimiter series is Advanced Bark Correction Technology, which delivers consistent and instantaneous correction, while virtually eliminating false corrections caused by external noises. And it all works right out of the box with a convenient Autorise setting that automatically programs the stimulation intensity level based on the barking behavior of each individual dog. Or, choose manual or vibration options for alternative modes of correction. This lightweight, compact device is the perfect training tool for any dog with nuisance barking. The BarkLimiter features a user-replaceable, long lasting (10-month) CR2 battery.
