Which is better a prism or a mini prism?

Mini prisms will give you the greatest amount of accuracy, but only at close to medium range. They’re smaller in size, which make them more convenient for storage and transport. And they can be attached to any type of survey pole.


Optical Surveying Reflector Prism Installation

Monitoring prisms should be installed using the following guidelines:

  • Attached to a rigid structure that is sufficiently stiff as to not move through a single monitoring cycle
  • Located to minimize the effects of temperature and radiant heat on a target
  • Installed with clear sight lines back to the total station
  • Avoid sight lines that require shooting through a fence or another mesh
  • Avoid sight lines shooting just past corners which can cause refraction
  • Avoid sight lines that include a source of heat that can cause a heat shimmer
