Sounds all correct to me and besides had we acknowldeged your presence it was likely that you would of all followed, rather than just the one member of your squad.
As it stands we found the lorry long before the ladies and the container and the back wall and even the pipes, just not in the order we intended.
Fun to dive, in what was 20 - 30 cm visibility in places. I did a test at one point and when I stretched my arm out my hand was no longer visible.
That said we could still hear the ladies when they were close by, easy to tell by the clacking sound their knitting needles make underwater. LOL
