Not sure if you got the help you were looking for it's not an easy or straight forward interpretation based on the video clip photos. I tend to agree with your interpretation however, with the absence of any clear or distinct pictures you could also be looking at a couple of very different interpretations.

You will need a good metal detector if you proceed with your current interpretation. Best of luck stay safe!
