The small, discreet BuzzClip mobility device provides hands free detection of waist or head level height obstacles. Used as a complement to a white cane or guide dog, it clips to the user's clothing and vibrates with increasing intensity as an object comes within detection range . With 2 sensitivity ranges of 3 feet or 6 feet, it can be used either indoors or outdoors. Within the 6 foot horizontal range, it can detect objects within 3 feet vertically from the Buzzclip, generally covering from the waist to the head, when the Buzzclip is clipped to a shirt lapel. It will stop vibrating after 5-7 seconds of no movement, allowing the user to stand and talk to friends without vibrations. Rechargeable battery lasts approximately 10 hours on a charge.
