Metal detecting rivers

[Waterdog]

I wanted to get some ideas of hunting rivers with some current with a metal detector. While hunting completely under water and trying to stay in one area while swinging a metal detector. Has anyone ever come across this with any success ?

Curious how well anybody has done in a small river and why you think you did? I've been toying with hunting a local river for years but keep finding something else to do. It's mostly shallow (less than knee deep) but with deeper holes for swimming or fishing. A large percentage of the river is hard rock bottom, and I would figure that would make it good for hunting old rings/coins. I'm thinking the heavier objects would sink down into the cracks in the bed rock just like gold nuggets would. In the slower areas where there is deeper water the bottom tends to be mud and I would guess wouldn't be productive since chances are the coins/rings could be buried several feet or more. One other area I'm wondering about is spots where rocks and shale gather. Those tend to be heavier items and if the current has stuck a bunch of shale in one area I don't see why it wouldn't also deposit coins or rings there? Would like some input on this. A friend keeps saying we should bring our sand scoops but I have a feeling there would be no use for them. More than likely you'd be prying coins out of cracks with something like a screw driver or digging them out of the shale deposits.

Years ago I hunted a few spots along this river and remember getting some clads in the cracks. Didn't hunt it enough to see any old coins or rings, though.
