copper ball markers
Copper ball markers represent a significant advancement in utility infrastructure marking technology, combining durability with precision locating capabilities. These spherical markers, constructed from high-grade copper, are engineered to provide lasting underground identification for various utility assets. The markers operate on the principle of passive electromagnetic technology, requiring no internal power source while maintaining consistent detectability throughout their operational life. Each marker is designed to withstand harsh underground conditions, including extreme temperatures, moisture, and chemical exposure, with an expected lifespan exceeding 50 years. The spherical shape ensures optimal signal reflection regardless of the marker's orientation, making them highly reliable for accurate utility location. These markers are specifically calibrated to respond to industry-standard locating frequencies, enabling precise detection at depths of up to 5 feet. The copper construction not only ensures excellent conductivity but also provides inherent resistance to corrosion and degradation. Installation is straightforward, typically performed during initial utility placement or subsequent maintenance operations, making them an ideal solution for both new infrastructure projects and existing utility mapping efforts.
