The Mommy I'm Here CL-305 Advanced alert child locator is a fun easy to use, affordable and effective way to locate and be notified when a child decides to wander. It works much like our original CL-103 wireless locator, but with a new, special distance alert feature that will actually alert you when your child decides to wander approximately 30 feet from you. When your child gets approximately 30 feet away from you, the keychain transmitter in your purse or pocket will chirp, alerting you that your child may have wandered. Then, just like our original Cl-103 product, you can simply press the button on your handy keychain remote to set off the adorable alarm on your child's teddy bear receiver. Fun, affordable, stylish and effective; Mommy I'm Here!
