Ordinarily, there is only animosity. True, sometimes there's a marriage of the two, but truth be told, it can be quite boring! I once "assisted" an archaeologist in a Chinese fishing village, who followed me around as I showed him beeps, explained the TID of each, etc... But after a few swings over the first target, he planted a flag, and would not allow it to be dug (they would come back later with paint brushes, screens, photo it, gps it, blah blah blah. Know you know us md'rs, would just plop down and dig the sucker, right? I ended up flagging a few dozen signals, while he made copious notes of the TID, size (based on beep smear), etc... I suppose it took him a week to dig those.
I have heard of others who assisted in archie digs, and had the same deal go on. Nothing wrong with that, if that's your thing, but don't believe that you'll go out there and just practice beeping and digging as we're all accustomed too. A rare exception *might* be when an archie knows that they can't cover all the ground, and a place is about to be cemented over, etc... blah blah. In that case, I have had an archie agree to dig some random targets, on site, right then. But this is rare. Even in those "lost cause - might-as-well" cases, most archies will let the targets sit and rot, because, afterall, 3 centuries from now, a future archeologist, and future generations, can "enjoy" the items when future digs are done.
Although this is bleak, I still enjoy kissing up to archies though, sharing data, getting in the "in" circles, etc.... because it can reveal site tips

Yup, sheep in wolves clothing 8) Oh well.
