joke: I know a forum member who is very proficient with photoshop and doctoring animated gifs…
let’s wait and see what he comes up with 
but seriously…
the picture above is a screenshot from the video you posted earlier:
the contours of whatever is in his trouser pocket does not look even close to the rounded shapes of a typical rangefinder, which is very compact!
btw: why would this contour not be similar to that of his wallet?
in other words: where is/was his wallet?
that thing in his trousers can very well have been his wallet and his access ticket to the rally area!
