US Patent:

Filed:
Feb 8, 2001
Appl. No.:
09/780116
Inventors:

International Classification:

US Classification:
033/35500R, 033/348000
Abstract:
An direction determining instrument provides an image reversing device positioned for siting a fixed indicator indicia and a mirror image reversed compass rose supported for rotation about its center. The compass rose is enabled by a magnetic device such as a magnet, for seeking magnetic north. The image reversing device, compass rose, and fixed indicator indicia are arranged and positioned so that the fixed indicator indicia and the rotatable mirror imaged compass rose are visible in the image reversing device as a non-reversed compass rose superimposed on the indicator indicia such that rotation of the compass rose appears to move in the direction of rotation of the instrument.
