Which component of a lensatic compass contains two circular scales?

The component of a lensatic compass that contains two circular scales is the compass dial. The compass dial is where you read the direction indicated by the needle, and it typically includes markings that allow the user to determine bearing angles. These scales often represent degrees from 0 to 360, essential for navigation and orienting oneself correctly.

The presence of two circular scales on the compass dial enables users to cross-reference and understand their positional data better, improving overall navigational accuracy. The inner scale is often used for measuring magnetic bearings, while the outer scale may represent true bearings or other item-specific indications depending on the design of the compass. This design feature enhances versatility and precision, making the compass dial a critical component for effective navigation.
