This Outdoor Ultrasonic Anti Bark System is designed to deter barking outdoors by blasting an ultrasonic sound, which is safe and effective. Its microphones are capable of verifying sound from up to 50 feet, and you can manually adjust the sensitivity. Made from durable plastic, the emitter is waterproof and weatherproof. It's designed to look like a birdhouse so that you can place it on a tree branch, a pole or a fence stylishly.

Tips:

• Place the unit no higher than 5 ft from the ground.
• Face the front of the device towards the dog.
• Make sure there aren't any large objects between the device and the dog. The sound doesn't travel well through fences, trees, or walls.
• Don't use this bark control device on dogs who are deaf or hard of hearing. They won't respond to the ultrasonic tone.
• Turn off the device when not in use. This helps prevent dogs from becoming desensitized to the sound.
• Add additional units to cover areas larger than 1/4 acre.
• Don't use this product inside your home. The ultrasonic sound will bounce differently indoors.
• To improve battery life, turn unit off when not in use.
• While the unit is weatherproof, it shouldn't be submerged in water. If water enters the microphone, the device might not work until the microphone dries
