To use a prismatic compass, first ensure it is set up correctly by adjusting the azimuth ring to align with magnetic north. Then, hold the compass level and sight your target through the prism while reading the azimuth on the compass dial. Ensure you compensate for any declination angle if needed.

what the function of surveyor compass
Local attractions such as buildings or metal objects can affect the accuracy of a prismatic compass survey by causing magnetic interference. This interference can lead to errors in compass readings and, consequently, inaccurate survey measurements. To minimize these effects, surveyors should identify and account for local attractions during their surveys, employing techniques such as taking multiple readings and using a declination correction.
The prismatic compass is a type of compass use for survering a land.
If you mean the difference between a compass and a compass rose: The compass is the complete instrument. The compass rose is the degree wheel printed under the needle.
A surveyor's compass, or a circumferentor is a device used in surveying to measure horizontal angles. It is used by directing the line of sight.
A navigational compass shows the way to North. A mathematical compass (actually used in the plural: compasses) allows you to draw circles accurately.
