Schonstedt GA-72CV Magnetic Locator

This locator detects the magnetic field of any ferrous object covered by ground, pavement, water or snow. Designed for one-hand operation, simply point the locator toward the ground and move it from side-to-side in a sweeping motion. When the locator comes within range of an iron object, an audio signal is given. The GA-72CV is unique because it provides both audio and visual indicators of the signal strength and polarity which will help you pinpoint an object, determine its orientation, and identify magnetically detectable non-metallic duct, cable and pipe. By simple analysis, the signal peaks will help you determine if objects are upright or on their side. Tone frequency increases or decreases with gradient-field intensity. Both units can locate well casings up to 15 feet deep, 55-gallon drums and cast-iron pipes up to 8 feet deep and much more; however it does not respond to aluminum, brass, copper, etc.
