I'm stuck at the chasm in Scanner Sombre
Solution 1:
After many, many falls trying to jump at every angle between the outcrops, I have found the way to get across.
Don't try and jump. Simply hug the wall to the left - there is a narrow ledge. Follow it round to the leftmost end and there is a small jump to the other side, where another ledge brings you back up to the Burst Scanner. In fact the location I stood to take the screenshot in the post above is exactly on the path to go round the ledge. D'oh!
