ABSTRACT:
Preferred forms of viewing apparatus according to the teachings of the present invention are shown as including an enclosed and elongated see-through passage having a hooded front opening. The rear end of the enclosed and elongated see-through passage includes a visually opaque annular perimeter portion extending around a rear opening of a size smaller than the front opening. The effect of the passage, the size relationships of the front and rear openings, and the annular perimeter portion is to separate the targeted object from its immediate surroundings and to create a visual window effect rather than a tunnel effect. In its most preferred form, the passage has a constant size throughout its length and the annular perimeter portion extends radially into the passage. The viewing apparatus includes a camouflage cover which can be removably secured thereto and a range finder on the annular perimeter portion for judging distances to the targeted object. In preferred forms of the viewing apparatus including sighting members within the passage according to the teachings of the present invention, apparatus for providing windage and elevation adjustment is incorporated with the enclosed and elongated see-through passage.
