The part of the lensatic compass that contains the sighting wire or front sight, along with two luminous sighting slots or dots for night navigation, is called the "lens" or "sighting lens." This component allows the user to align the compass with a distant object to take accurate bearings. The luminous features aid visibility in low-light conditions, enhancing navigation during nighttime.
The compass cover
A lensatic compass has a sighting lens and a floating dial for precise navigation, while a mirror compass has a mirror for sighting and a fixed dial for general direction. Lensatic compasses are more accurate but require more skill to use, while mirror compasses are easier to read but less precise.
In a lensatic compass, the siding wire or front sight is typically located on the top of the compass housing, while the luminous citing slots or dots used for night navigation are usually found on the compass dial or within the sighting mechanism. The siding wire helps align the compass with a specific direction, while the luminous features facilitate visibility in low-light conditions. This design allows users to effectively navigate both during the day and at night.
There are three main types of compasses used for navigation and outdoor activities: magnetic compasses, digital compasses, and lensatic compasses. Magnetic compasses use a magnetized needle to point towards the Earth's magnetic north. Digital compasses use sensors to determine direction and often have additional features like GPS. Lensatic compasses are more advanced and have a sighting lens for more accurate readings.

The technique used almost exclusively for sighting is the "line of sight" method. This involves visually aligning two points or objects to determine direction or location, often utilized in navigation and surveying. Additionally, tools like theodolites or sighting compasses enhance accuracy in this method. Overall, line of sight is fundamental for tasks requiring precise visual orientation.
