Miniguide Mobility Aid

The verdict

The Miniguide sends out ultrasonic pulses and listens for the echo, vibrating faster the closer an object is, with a headphone jack if you prefer tone feedback to vibration. Gap-finding modes lower the sensitivity at distance so doorways show up more clearly.

Miniguide Mobility Aid — about $499 at LS&S · star rating unverified in our research · Blind pick (no sight needed) — the pocket-size ultrasonic echo-location aid that vibrates faster as obstacles get closer, a second set of senses for the space your cane cannot reach, for blind travelers who want warning about head- and chest-height obstacles.

It is a small unit — 3 inches long, 1.5 inches wide, 0.9 inches thick, 2.32 ounces — running on a single CR123A battery the maker says lasts for months, and it is made in Adelaide, Australia by GDP Research.

Blind details

For a blind traveler, the Miniguide covers what the cane sweeps under: branches, signs, open car doors, and anything at waist height and above. Learn its vibration language at home first — faster buzz means closer object — and use it alongside your cane or guide dog, never instead of them. It is splash-proof rather than waterproof, so keep it out of deep puddles and dry it out if it gets wet inside.

Honest caveats: At $499 this is a major purchase, and LS&S lists it as available for pre-order rather than in-hand stock, so confirm the lead time before ordering. It does not detect drop-offs, stairs, or slippery surfaces, and it is explicitly a supplement to a primary aid, not a replacement. The CR123A battery is a camera-style cell, so keep a spare on hand.
