Well, I watched the video. (Beats workin'.) I wasn't able to watch in very high quality, being limited to my phone, so I may have missed something important. The video did make me want to visit him, to pet his dog. Nice looking dog. A basset or basset mix, I think. It didn't even bite SaskMick when he told it to bugger off.
I'll summarize for those who don't want to, or can't, watch it:
First, SaskMick finds a pipe (I think he says a plastic pipe covering a wire) in his yard with the dowsing rods (I assume he knew where it was; we never see the pipe), and marks it with a jar. He then asks Leslie (his wife?) to try to find it (remember, it's obviously marked), and she apparently fails.
He then turns his back and has Leslie walk until he tells her to stop, which he does when the rods move. (The camera remains with his POV; we don't see Leslie walking now, but we see the rods.) Both times, when he turns back she has stopped at the jar.
It should be noted that there is a quite strong wind, which SaskMick comments on during the video.
Each time the rods move, they do so dramatically, almost as if there were some invisible force moving the air swiftly.

(Actually it appears that the left rod does most of the moving.)
So, in sum, nothing new here. You can skip the video, unless you like dogs.
Edit: Daggone it, Loss Leader beat me to it while I was watching/posting.
