The Schonstedt GA-72Cd magnetic field locator is used to find iron and steel objects that are underground. It provides audio detection signals that peak in frequency when the locator's tip is held directly over the target.
The GA-72Cd has an easy-to-read digital and bar graph display that shows signal strength and polarity. It is most popular for UXO and demining applications.
