I don't have much sense of the reasonably expected or maximium performance of this ability. They give a few sensational demonstrations, but how accurate is it (as in complete, correct, and consistent)? How fast? In what environments? How granular? Is it practical for everyday use?
For some interesting context, here is a description of dolphin echolocation:
https://www.britannica.com/animal/cetacean/
"The amount of information obtained by an echolocating dolphin is similar to that obtained with the eyes of a sighted human. ...
Toothed whales use extremely high frequencies, on the order of 150 kilohertz, for refining spatial resolution from their echoes. They are capable of “seeing” into and through most soft objects such as other dolphins, though the effectiveness of toothed whale echolocation drops off at distances greater than about 100 metres."
Maybe with enough practice ...
