Echolocation is a tool used by bats and dolphins. They emit sounds and can navigate based on how the echoes return. But echolocation isn’t restricted to animals.

Ben Underwood is blind. He lost his eyes to cancer when he was 2-years-old. But you might not know it, watching his everyday life. Ben gets around fine without the use of a cane or guide dog. In fact, he rollerblades, has pillow fights and even plays video games. He uses echolocation. He is so good at it, you’ll be amazed.
