Help curb and correct nuisance barking from your pet, by using the Garmin BarkLimiter 2VT. It uses accelerometer-based bark identification to distinguish between repetitive barking and other sounds. Then it corrects bad barking behavior with on-collar vibration and/or tone prompts. BarkLimiter 2VT comes ready to go right out of the box and works with the free Garmin Canine app on your compatible smartphone or tablet. You'll use the app to set up your BarkLimiter 2VT device and enable your phone or tablet to serve as a wireless component for your system. The app lets you remotely turn the collar device's vibration and tone prompts on or off. Plus, you can also review bark history data to see what times of day your dog tends to trigger corrections. The BarkLimiter 2VT is used with the included 3/4" black strap, or easily snap onto your dog's existing collar (up to 1 wide and up to 0.12 thick). It also includes a charging/data cable.
