Miniguide US is a vibrating and audible electronic mobility aid designed for use by individuals who are blind or deaf blind or have low vision. This hand-held electronic travel device uses ultrasound to detect objects, and gives tactual or auditory feedback by vibrating or chirping more rapidly as the user approaches an object. The device can help a blind person avoid obstacles and overhangs, locate landmarks or items such as mailboxes or trash cans, and find open paths through crowds at a range of 20 inches to 26 feet depending on the size of the object. This customized version of the Miniguide (see separate entry) has an extra push button for access to the gap finding modes. The device comes with a print guide book (model 1-07006-00) or a braille guidebook (model 1-07007-00). An optional instructor's remote unit allows instructors to receive the same tactual feedback as their students. The remote unit attaches to the main unit with a 12-foot-long cable (included), and comes with a Remote Unit User's Guide on cassette and in print. POWER: Uses triple-A battery (included). OPTIONS: Reference sheet pack (5 print, 5 braille); instructor's remote unit.
