Our Customers Say…

“I just wanted to let you know how impressed I am with the Pinpointer. I’ve located approximately 40 faulted conductors in 3 days, and have not wasted an ounce of fuel excavating these locations to find nothing. Most of my locates have been right on top of the fault. Once again Thank You!”
