Comparison between Prismatic Compass and Surveyor’s Compass

The terms "Prismatic Compass" and "Surveyor's Compass" are used interchangeably and refer to the same type of surveying instrument. There is no difference between the two, and both refer to a specialized tool used by surveyors, engineers, and construction professionals to measure angles and take accurate readings for various surveying and construction projects.

In summary, the Prismatic Compass and Surveyor's Compass are the same instrument and are used for the same purpose. They both consist of a circular dial, a sighting mechanism, and a removable prism, and are used to measure angles, determine the slope of the ground, and take readings in areas where visibility is limited. They are essential tools for precise surveying and construction work, and their ability to measure angles makes them an essential tool for many professionals in these fields.

What are the difference in Bearing, Graduations, Needle, Scale & Tripod in Prismatic Compass and Surveyor’s Compass 

The components of a Prismatic Compass and a Surveyor's Compass are essentially the same and include:

Bearing: The circular dial that rotates and is used to measure angles.

Graduations: The markings on the bearing that indicate the measurement of the angle.

Needle: The magnetic needle inside the compass that aligns with the earth's magnetic field.

Scale: The markings on the circumference of the bearing that are used to determine the measurement of an angle.

Tripod: The stand used to hold the compass steady while taking readings.

In terms of differences between Prismatic Compasses and Surveyor's Compasses, there may be variations in the design and features of different brands and models, but these components are generally the same. Some compasses may have more advanced features, such as a built-in bubble level or a higher level of accuracy, but the basic components and functions remain the same. Ultimately, the choice of a Prismatic Compass or a Surveyor's Compass will depend on the specific needs and preferences of the user, as well as the requirements of the task at hand.
