Schonstedt MAGGIE Magnetic Locator – High Sensitivity Digital Ferromagnetic Detector with Visual Display (Part No. 518836)Highest Sensitivity in a Schonstedt Locator | Ergonomic Design | Audio & Visual Targeting | Made in the USA | 7-Year Warranty

The Schonstedt MAGGIE Magnetic Locator is engineered for professionals who demand maximum detection sensitivity and real-time feedback when locating deeply buried ferrous objects such as survey markers, valve boxes, septic tank lids, rebar, steel pipe joints, and manhole covers. Combining the pinpoint accuracy of the GA-52Cx with the single-handed, ergonomic design of the GA-92XT, the MAGGIE is the most sensitive and user-friendly magnetic locator in Schonstedt’s lineup.

This locator features an integrated digital display that visually represents signal strength and magnetic polarity, providing real-time data to support fast, confident target acquisition. It’s housed in a lightweight, high-impact ABS body, rated IP54 for protection from dust and water exposure. A 4-level gain adjustment, volume control, and one-hand operation make it ideal for surveyors, contractors, utility crews, and public works professionals looking to minimize search time in demanding conditions. The MAGGIE ships with a padded soft case and is backed by Schonstedt’s industry-leading 7-year warranty.

Ultimate Sensitivity Meets Field-Friendly Design. The Schonstedt MAGGIE is built for professionals locating ferrous objects in urban, residential, or remote environments. Its extended sensor spacing and advanced HeliFlux® technology allow for detection of ferromagnetic objects up to 20 feet deep, depending on size and soil conditions. The expanding bar graph shows both signal polarity and strength, giving users accurate visual confirmation of the target and helping to determine its orientation underground.

Operators can quickly change gain or volume settings with the easy-access membrane buttons, and the 4-segment battery indicator ensures you never lose power unexpectedly. The 32.5-inch frame and balanced pistol grip reduce fatigue during extended use, and the soft case with shoulder strap makes transportation easy across job sites or rugged terrain.
