How many sights does a standard compass feature?

A standard compass typically features two main sights, which are used to line up the compass with a distant target to ensure accurate navigation. These sights are usually positioned along the sighting plane of the compass, enabling the user to align the compass straight towards the object they want to navigate towards. This dual-sight system is crucial for improving accuracy in navigation and helps in taking precise bearings while reading the compass against the background landscape.

While other options suggest a different quantity of sights, the standard design that includes two sights is widely recognized in various models of compasses used for land navigation, strengthening the validity of the answer.
