The TW-6 is an industry leading "two box" underground utility locator, designed to find pipes, cables, and other metallic objects. This unit is ideal for conducting blind searches and tracing out utility lines. Besides being a cable and pipe finder, the Fisher TW-6 can locate utility lines and function as a water line locator.

The TW-6, like earlier models, will be primarily used by water departments, telephone companies, electric power companies, gas companies and petroleum pipeline companies to know where to dig, and sometimes more importantly where NOT to dig in making repairs or rearranging buried lines.
