A surveillance shield comprising a rigid, substantially inflexible mirrored plastic panel, and at least one aperture defined by the panel, the aperture positioned in the panel such that a user may peer through the aperture while carrying the shield. The shield may also include a second mirrored plastic panel, each of the plastic panels having a frame member connected at an edge portion of the panels, the panels detachably connected to each other in a vertical attitude, each of the panels having a substantially optically correct outward facing surface to reflect accurately the surrounding environment and thereby substantially conceal the appearance of the shield. Preferably the aperture is positioned such that a user is substantially concealed by the shield while the user carries the shield and simultaneously peers through the shield to observe game, people or a target.
