What is the primary use of a bore scope during a visual examination?

The primary use of a bore scope during a visual examination is to examine internal parts of pipes and components. A bore scope is a specialized optical device designed to provide a clear view of areas that are difficult to access, such as the inside of pipes, engines, and other enclosed spaces.

This capability allows inspectors to identify potential issues like corrosion, blockages, or wear without the need for invasive procedures. Depending on the application, bore scopes often have adjustable lighting and high-resolution cameras to provide detailed imagery, thereby aiding in the assessment of the internal condition of various components. This is particularly crucial in industries such as aerospace, automotive, and construction, where internal inspections are essential for safety and maintenance.

In contrast, while other options involve measurements or examinations of external features, they do not represent the primary function of a bore scope, which is to focus on internal inspection.
