That's not true. All the dowser needs to do to claim the prize is to have a
success rate that is significantly higher than expected by chance alone.

The true skeptics should at least try it before being so adamant that
it doesnt' work.

I think you have that backwards: the proponents should show evidence that it
works, before claiming that it does.
