a telescopic pole with a prism on top used in surveying for accurate measurements and positioning
A prism pole is a tool used in surveying to support a survey prism, which is a reflective device used to measure distances. The pole is typically made of lightweight materials like aluminum and is adjustable in length. It allows the surveyor to position the prism at the correct height for accurate measurements. The prism reflects signals from a total station or other measuring instruments, helping surveyors determine distances with high precision. Prism poles are essential for tasks like land surveying, construction, and road building, where accurate distance measurements are required.
