The Rhino Mag marker is designed to be buried directly above underground utilities such as plastic pipes and fiber optic cables. These colorful and high-strength permanent magnetic markers are easy to install can be detected at depths up to 10 feet (3 m). The color-coded Rhino Mag is permanent and never needs to be recharged. The Rhino Mag can be installed during new construction. To install, simply place it vertically in the soil with the “black” end down and backfill carefully to ensure vertical orientation for maximum detection. The Rhino Mag can be located by magnetic locators (not metal detectors). Available colors are: Yellow/Black, Red/Black, Blue/Black, Green/Black, and Orange/Black.
