Abstract: A blind device for use in concealing a user from view during the course of hunting or observing wild geese includes a shell goose decoy mounted on a support structure that supports the shell in an elevated, generally horizontal position above the ground to provide a substantially unobstructed space below the shell to accommodate and conceal at least a portion of the user's body, and enables the user to swing the shell with generally horizontal movement about a generally vertical offset pivot axis of the support between a covering position in which the shell overlies and conceals the user and a revealing position in which the shell is swung out of the way to one side of the user, providing the user with substantially unobstructed overhead viewing and freedom of movement.
