An omnidirectional torpedo level composed of non-ferrous material has a central web and parallel side flanges defining a torpedo level geometry. The central web and side flanges define windows within which are mounted vertical and horizontal tubular spirit level elements that permit selective orientation of the side flanges to determine when surfaces being engaged by the side flanges are either vertically or horizontally oriented. A rotary protractor is mounted to the central web and contains a spirit level tube for accurate positioning of the side flanges with respect to the selected angle of the protractor. Magnet members are mounted to one or both of the side flanges and serve to support the level device in hands-off relation when in contact with ferrous metal objects. A circular omnidirectional level enlargement is provided at the upper end portion of the level body and provides for support of a circular omnidirectional level device having a circular lens marked with circular positioning indicia. Liquid and air within the circular omnidirectional level device form an orientation bubble which is aligned with the circular indicia to confirm vertical alignment of the reference surfaces with respect to "x" and "y" axes.
