Description: Special Report
Abstract: This report describes, in basic language, how to operate buried-utility locators and what the locators' uses and limitations are. Its scope is limited to locators using the principles of magnetometry, induction balance, magnetic induction and radio-frequency tracking. Magnetometry and induction balance work best for near-surface isolated targets such as valve boxes and manhole covers. Magnetic induction will locate all types of metallic utilities, including cast iron and steel pipe, power cables and communication lines. Radiofrequency tracking traces unpressurized non-metallic lines that have available access for introducing a floating transmitter into the line (e.g., sewer or storm drains made of plastic or vitreous tile pipe).
