The video above is a 47 minute documentary on Ben Underwood and his amazing capabilities with echolocation. This is one of the first videos I saw on echolocation that inspired me to create this blog.
Take some time and watch this video for a good look at this unique individual. Ben Underwood passed away in 2009 and his mother has created a website where you can learn more about him and show your support if you'd like to leave a comment.
Enjoy the documentary!
