A solar compass device having a first disc member provided spaced apart time markings indicative of the time of day and disposed in a counterclockwise direction in a circular ring pattern thereon. A second disc member is rotatably displaceable with respect to the first disc member to permit rotational displacement between the first and second disc members with the members disposed in substantially parallel planes. A single fixed indicating marking is provided on the second disc member and aligned with a south end of a north-south radius passing through a center point relative to the ring, and the ring. In operation, the first disc member is oriented with one of the 12 o'clock marking, aligned substantially in the direction of the sun, with the fixed indicating means having been aligned with a marking indicative of approximately the time of day. With the discs so oriented, the north end of the radius is automatically aligned in the direction of the north pole.
A solar compass device comprising a first member having spaced apart markings indicative of time and disposed in a counterclockwise direction in a circular ring pattern thereon, a second member rotatably displaceable with respect to said first member to permit rotational displacement between said first and second members with said members disposed in substantially parallel planes, and a single fixed indicating means on said second member aligned on a radius between a center point relative to said ring, said radius representing a north-south axis with said indicating means being disposed at a south end of said axis, said indicating means when aligned with a marking indicative of approximately the time of day, and said first member when oriented with one of said markings which is representative of 12 o'clock aligned substantially in the direction of the sun, the north end of said axis is automatically aligned in the direction of the north pole.
