I look at it as mostly a blind/archery decoy when you are trying to get a bird at 4yds to put on a show. It sits really low because it lays on the ground I would think most fields I hunt it would be worthless by May with the grass completely covering it rendering it unseeable.
Sure it would work in areas with a high population of competitive birds but it wouldn't have a place in my vest for the style hunting I do. honestly while I have some decoys we rarely need or use them.
