GA-72Cd Schonstedt Magnetic Locator

Schonstedt’s underground magnetic locators have been setting the standards for reliability and dependability for over 30 years. They are designed to withstand the rigors of daily on-site usage and a wide range of environmental conditions.


    • Unmatched sensitivity allows you to find what you’re looking for quickly, without the risk of passing over your target.
    • Our locators last 100% to 250% longer than others, making your investment a solid one.
    • Audio signal and 3-digit LCD readout 85% of the Surveyor market can’t be wrong.


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.

No. 1 Around the World in Performance and Reliability

Only two Controls! Designed for one-hand operations, the On/Off-Sensitivity and Volume controls are located on the underside of the cover on both locators. This provides easy access, protects the knobs and contributes to their overall ruggedness and dependability.
