Utility marker balls identify the above-ground location of buried utility lines and pipes. They help contractors and excavation crews find and avoid contact with underground power, cable, gas, and water lines.

These transmitters connect to above-ground equipment, stakes, or rods and send a signal that travels underground. This signal is picked up by compatible underground utility locators and used to mark the precise location of underground utility lines and pipes.

Signal clamps pair with compatible underground utility locators as part of an active tracing system. They fasten or clamp around above-ground conductors and transmit electrical signals to find the exact location of underground utilities and pipes.

These carrying cases hold two utility locators and accessories. They have a zipper closure to secure and protect instruments and have a shoulder strap that makes transporting equipment to the field more convenient.
