Quote Red ~ "Hi Snowy, I've found on damp sand where the scoop cut holds form, taking slightly less in each scoop allows more room to shake sand free. You do need to work more quickly on the wet sand as the walls collapse with water seeping up...take a full scoop then dump it to one side...check if the target is out of the hole, if not, go in for the next scoop.
Cheers"
Thanks Red, yeah I have had the damp sand really ball up and thump & flop around the scoop...
Then the more ya shake it; the denser it gets !!!
No problems at all with wire mesh though, and it gets sifted quick smart too.
There was a post once from a guy, who used a plastic bucket with no bottom in it, he shoved this bucket down into the sand over his pinpointed target.
And when he scooped out the wet sand from within the bucket, the walls of the bucket prevented the sand and water from caving in!
I do remember leaving a good sounding target at a Melbourne beach years ago,I just couldn't burrow down quick enough, and the target seemed to be
going deeper and deeper! Water just kept roaring in !!!
Didn't upset me really...
NOT MUCH !!! 
I just convinced myself it was just a rotten aluminium can base, and calmly went on with my life !!!
