GA-72Cd Features

Schonstedt’s underground magnetic locators have been setting the standards for reliability and dependability for over 50 years. They are designed to withstand the rigors of daily on-site usage and a wide range of environmental conditions.

GA-72Cd_digitalreadout The Schonstedt level of sensitivity allows you to find what you’re looking for quickly, without the risk of passing over your target.


The GA-72Cd Locator detects the magnetic field of iron and steel objects. It provides audio detection signals that peak in frequency when the locator’s tip is held directly over the target. The GA-72Cd has the option of nulling or peaking.
