It is different - not metaphysically or entirely, but... echolocation for humans is rather long-wave (although it's experienced as vision.) You can't - I couldn't - see a door edge wise so I could walk into doors pointed right at me. But bats want it for insect location, I'm betting. Much more precise, much higher frequency.

Sure, bats echolocation is more precise, basically due to the shorter wavelength, which is quite obvious if you think about it. However, what I was trying to hint at is that the function is likely equivalent, while the implementation is definitely more sophisticated when it comes to bats. The function is to build an internal representation of the external world.
