Interesting topic. The use of echolocation is really amazing, certainly when I read how this Ben Underwood is able to use it. I use something similar sometimes too, for very simple things like finding an open door in a dark room, but I think you have to be born blind to develop this ability like he did. (I have never used klicking sounds but klap in my hands or bounce with my feet on the floor)
I'm wondering if he would be able to use it in an area with lots of background noise, like in a big city.
I have got rather bad night vision myself, so when I walk on a path I use the sense of my feet to feel If I'm still walking in the middle of the path(you feel you are waling on hardened sand or other material), and when I feel the "tracks" on the ground I know what direction the road is going. And when I want to look at a dark object in the dark, I don't look at it directly, but focus beside it. I can't remember where I learned this trick, but it works really well for me.
True, but IMO you should never put complete trust in how it was before. When I come home late sometimes, I don't put the lights on to wake nobody else up, but when for example somebody has put a bag where it shouldn't belong, or something, that can be really inconvenient(and painfull).
(I don't use a flashlight at home because some years ago neighbours called the police because they thought there was a burglar in our house when they saw my flashlight shining through our windows, so I learned my lesson)
I almost always put my hands in front of me to make sure I feel some object with my fingers before my head makes an unpleasant collision with it. But I suppose everybody does this, or am I wrong?

When your light goes out you can't see your hand infront of your face ! sometimes I turn my light out for the fun of it just to try my night vision out
