What is the angle/spread of the sensor? eg if you point directly in front of you, then at 2 metres away how wide and tall does it detect things?

In the video you can see someone duck out of the way of an overhanging branch. I'm curious how much they had to move the sensor to figure that out.

Sure, range and sensitivity can be adjusted from the App, maximum ratings are 5 meters and 35° angle at the sound cone. So at two meters you would be able to detect head level obstacles with no problem. To improve the receptivity you can also slightly bend your elbow to give a little angle to your forearm and aim the band slightly up, that will catch even the ceiling of your room, fortunately the IMU permits us to understand the position you are aiming and trim the sound cone only to cover areas that represent a hazard, trying to drag attention of the user only with needed.
