Surveying Rods & Poles

A surveying pole, also known as a prism pole or a range pole, is a tool used in land surveying to measure distances and angles accurately. It typically consists of a long, straight pole marked with measurement increments and may include a prism for use with total stations. The primary use of a surveying pole is to provide a stable and precise reference point for measurements, ensuring accurate data collection for mapping and construction projects.

A prism pole is used to hold a prism at a known height so that a total station or robotic total station can measure distances and angles accurately. It provides a stable and consistent target for line-of-sight measurements. Prism poles are essential for layout work, boundary surveys, and construction staking, where precision alignment is required between instrument and target.

Choosing the right surveying pole depends on several factors, including the type of survey, the equipment you are using, and the terrain. Key considerations include:

• Material: Poles can be made of aluminum, fiberglass, or carbon fiber. Aluminum poles are durable and cost-effective, fiberglass poles are lightweight and non-conductive, and carbon fiber poles are the lightest and strongest but also the most expensive.
• Length: Standard lengths vary from 2 to 4 meters. Consider the height requirements of your survey.
• Sections: Some poles are telescopic, allowing for adjustable lengths, which can be useful for different surveying conditions.
• Compatibility: Ensure the pole is compatible with your prism or GPS equipment. All of the poles sold here at Bench-Mark use the standard 5/8″ survey thread. 

Telescopic surveying poles offer several benefits, including:

• Adjustability: They can be extended or retracted to suit various measurement heights, making them versatile for different surveying tasks.
• Portability: When retracted, they are compact and easier to transport and store.
• Stability: Quality telescopic poles have secure locking mechanisms to maintain stability and accuracy during measurements.

To maintain your surveying pole, follow these tips:

• Regular Cleaning: Clean the pole after each use, especially if used in muddy or dusty conditions. Use a soft cloth and mild detergent.
• Inspection: Frequently inspect the pole for any damage or wear, especially at the joints and locking mechanisms.
• Proper Storage: Store the pole in a dry, secure location to prevent damage from moisture or accidental impacts.
• Calibration: Periodically check the pole’s calibration and alignment, particularly if it has adjustable sections, to ensure accurate measurements.

Yes, surveying poles are commonly used with GPS equipment for precise positioning. When using a pole with GPS, it is crucial to ensure that:

• Pole Height: The height of the pole is accurately known and properly accounted for in your GPS measurements to avoid errors.
• Stability: Use a bipod or tripod to stabilize the pole, especially in windy conditions or on uneven terrain.
• Compatibility: The pole and GPS equipment are compatible, with appropriate mounting brackets and connectors. All of our poles are compatible with any of our Hemisphere and Nano receivers.
