Should study maps on the internet, like Google earth, and learn where there is water, ponds, and swamps, where huntable ducks may congregate. And I'd get my walking feet in shape for some serious treking.

Of a newbie I would require that they know what eye will aim down the barrel of a shotgun and what eye is their POWER eye. And if they are different, I'd do some changing or some serious practice.
And anyone who doesn't know POWER eye, may want to retire from duck hunting, before they even start, if thus affected.
