发明名称 Compass
摘要 The improvement of the present invention provides a camper's compass having a plate or member, such as an arcuate bow, having a direction pointer, which is pivotably mounted over the compass housing in such as way that it can swing between a normal forward position in which the compass is oriented in the desired direction of travel, and a diametrically opposed or reverse position. By pivoting the arcuate bow or member from its forward position to its reverse position, the user can set the return direction to the point of departure on the compass. The direction of a reverse path back to his point of departure is readily determined without making any mathematical calculations or trying to use the orienting means of the compass in reverse positions. This simplified manner of setting a return path on the compass eliminates confusion which otherwise may occur and result in disorientation of a user in his attempt to return to his point of origin.
