    Q1: What is prism pole?
    A1: A prism pole is a tool used in surveying and construction to measure distance and elevation. It typically consists of a long, thin pole made of wood or metal, with markings or measurements along its length.

    Q2: How does a prism pole work?
    A2: The working principle of a prism pole is based on the principle of triangulation. The prism pole consists of a long, slender pole, usually made of aluminum or fiberglass, with a prism at the top. The prism reflects the light from a surveying instrument, such as a total station, back to the instrument. 

    Q3: What is the function of prism pole?
    A3: In surveying, a prism pole or range rod is used for marking the positions of survey stations and sighting these stations as well as the survey points. It can also be used for ranging straight lines.

    Tips: How to maintain prism pole?

    • Keep the pole clean. Dirt and debris can build up on the pole over time, which can affect the accuracy of measurements. Use a soft cloth or brush to wipe down the pole regularly, and be sure to clean the prism and target as well.
    • Check for damage. Before and after each use, inspect the pole for any signs of damage, such as cracks or dents. If you notice any damage, don't use the pole until it's been repaired or replaced.
    • Lubricate the locking mechanisms. The locking mechanisms on the pole should move smoothly and securely. Apply a small amount of lubricant to the locking mechanisms if they start to feel stiff or sticky.
    • Store the pole properly. When not in use, store the pole in a dry, cool place where it won't be exposed to extreme temperatures or moisture. Keep it away from direct sunlight and any sources of heat, such as radiators or heaters.

    Compact and convenient design
    The compact design of the 3.1 meter prism bar with measuring bipod greatly improved my field experience. It was easy to transport and installation was simple and straightforward. The collapsible prism pole makes it easy to store when not in use, and the adjustable legs of the bipod keep it stable on uneven ground. This product has simplified my surveying workflow and I appreciate the attention to detail in its design.
