Frequently Asked Questions
Want to learn more about prisms and surveying rods? Check out some of the most popular questions we receive below.
What is a Prism Pole?
Prism poles, also known as grade rods, are an instrument used by surveyors and other professionals who need to take measurements of grade elevation. They can be made from a variety of materials, but the most common are fiberglass, wood, and plastic.
How do I Use a Prism Pole for Surveying?
Extend the grade rod to its full length along with a transit or auto level. Start with the measurement points you need, and then hold the rod in a vertical position. Focus the instrument on the grade rod and record the measurement.
How Do I Calibrate and Maintain Prism Poles?
Regularly check the bubble vial calibration, clean the locking mechanisms, inspect for damage, and verify height measurements. Store poles vertically when possible to prevent warping. Our service department can perform professional calibration as needed. Stop by one of our offices for a free calibration on the pole's level vial.
What Surveying Accessories Complement a Prism Pole?
Essential surveying accessories include a bipod for stability on uneven terrain, a pole bag for transport protection, extra bubble vials, and adapters for different prism heights. The Seco Thumb-Release Bipod is particularly popular for rapid setup on challenging terrain.
Which Prism Pole Works Best With Robotic Total Stations?
For robotic applications, we recommend carbon fiber poles with TLV (Twist-Lock with Vial) mechanisms like the Seco Robotic Carbon Fiber Pole.
How Do Different Prism Heights Affect Accuracy?
Prism height directly impacts elevation measurements, with common heights being 135mm or 115mm from pole tip to prism center. Using the wrong height offset can introduce systematic errors. Most poles have graduated markings for direct reading, and adapters are available to achieve specific heights. Always verify that the correct prism constant is set in your instrument.
