Schonstedt’s underground magnetic locators have been setting the standards for reliability and dependability for over 40 years. They are designed to withstand the rigors of daily on-site usage and a wide range of environmental conditions. The GA-52Cx Locator detects the magnetic field of iron and steel objects, with unmatched sensitivity. Only two Controls! Designed for one-hand operations, the On/Off-Sensitivity and Volume controls are located on the underside of the cover. This provides easy access, protects the knobs and contributes to their overall ruggedness and dependability. Approximately 40 Hz idle tone in speaker. Tone frequency increases (or decreases) with gradient-field intensity. Comes with a carrying Case and 2 – 9V Alkaline Batteries (in unit). Has a 7 year warranty. Product Brochure. Product Manual.
