What is a unique characteristic of a Lenstatic Compass?

The unique characteristic of a Lenstatic Compass is that it is marked in a way that allows for easy reading of bearings, particularly in high-visibility conditions. The Marked in red for 360 degrees is designed to provide users with clear and distinct gradations that aid in navigation. This distinctive marking helps differentiate it from other compasses and enhances its usability in various environments, making it suitable for activities that require precise direction-finding, such as in navigation and military operations.

The other options do not accurately represent the characteristics of a Lenstatic Compass. While compasses may include specific features like color coding for different applications, the primary identifying factor of a Lenstatic Compass is its red gradation system that is utilized for efficient navigation.
