The Basics Part 1-1: Locating Methods
Most of the filming done for this training project took place at Staking University in Manteno, Illinois. The skilled trainers at Staking U are familiar with almost every utility installed on the campus as far back as the 1930s to 1940s, and this created the perfect setup to demonstrate different locating scenarios and techniques.
