Understanding the Function of a Sighting Mirror on a Compass
When it comes to navigating through the wilderness or open seas, a compass is an essential tool to have in your gear. But have you ever wondered what the sighting mirror on a compass is for?
The Basics of Compass Sighting Mirrors
A sighting mirror on a compass is located on the lid or base of the compass, and it is typically a small mirror that is hinged or adjustable. The mirror allows you to take a sighting of a distant object by lining up the reflected image in the mirror with the sighting notch on the compass base. This allows you to determine the direction you need to travel in order to reach your destination.
How to Use a Sighting Mirror on a Compass
Using the sighting mirror on a compass is a simple process, but it requires some practice to become proficient. Start by opening the compass lid and positioning the mirror at approximately a 45-degree angle to catch light from the sun or another bright object. Next, position yourself so that you can see the object you want to take a sighting of through the sighting notch on the compass base. Finally, adjust the angle of the mirror until the image of the object you want to sight lines up with the sighting notch on the compass base. The bearing displayed by the compass is the direction you need to travel to reach your destination.
The Benefits of Using a Sighting Mirror on a Compass
The main benefit of using a sighting mirror on a compass is that it allows you to take more accurate sightings of distant objects. In addition, a sighting mirror makes it easier to take readings in low light conditions or when the sun is low on the horizon. Some compasses are even designed with a built-in light source to make it easier to take readings in low light conditions.
A compass sighting mirror is a useful tool for anyone who needs to navigate through unfamiliar territory or open water. By taking accurate sightings of distant objects, you can stay on course and reach your destination with ease. Whether you are a hiker, camper, boater, or pilot, a high-quality compass with a sighting mirror should be an essential part of your gear.
