Locate your child in a crowd with the touch of a button from your remote. If you lose sight of your child, press the keychain transmitter and the teddy bear will chirp, alerting you of your child's whereabouts while at the same time drawing attention to the situation your child may be in. The teddy bear receiver delivers a loud 90db intermittent chirp/beeping sound that functions from over 150 feet away from the keychain transmitter. Teddy Bear is 2 5/8"L x 1 1/2"W. Keychain transmitter is 2 1/4". Both units are water and shock resistant, with long life batteries already installed. The cute Teddy Bear Receiver is fun to wear. Works well at the mall, in stores, airports, sporting events, parks or any other public venue where a child can quickly become lost or missing.
