Magnetic Locator Introduction

For over half a century Schonstedt has been the worldwide leader in designing and manufacturing underground magnetic locators.

It began back in 1953 with the development of magnetometers for military & aerospace applications, giving us today the GA-52Cx, the “yellow stick” that remains the choice of surveyors around the world to find underground markers, septic tanks, and other ferrous objects. The GA-72Cd soon followed, complete with extra-rugged construction, a visual display, and a sensitivity indicator that make it the underground locator of choice, especially useful in unexploded ordnance (UXO) and demining applications. Next came the innovative GA-92XTd, the extendable, easy-to-use and portable magnetic locator. The GA-92XTd retracts to fit in its holster (included), and extends for one-handed operation and fingertip control. The GA-92XTd has been further enhanced with a membrane switch style keypad and precision magnetic signal strength indicator.

Now comes The MAGGIE, a “Next Generation” magnetic locator that combines the best features of two flagship Schonstedt products—the sensitivity and precision of the GA-52Cx, and the single-handed operation of the GA-92XTd.
