I place mine downwind of the spread facing into the wind. One High and a couple low with one angled back and very close to the water. but basically from the years of using them you cam pretty much place them anywhere to get the ducks attention and it is up to them liking your spread as to if they come in or not. THe MoJo is just an attention getter and is only good for about the first week or 2 then they start to have the opposite effect.
