FIELD: methods and devices for air drift detection in ground. SUBSTANCE: method includes excitation of electromagnetic oscillations by means of wave radiation oscillator, and periodic determination of azimuth of air drift by maximum value of wave radiation at least in two points. Used as wave radiation oscillator is spark discharge sent by separate pulses with frequency of less than 50 Hz or more than 65 Hz. Device for detection of air drifter in ground has electromagnetic oscillator with drive and two directional aerials. Oscillator is made in form of spark discharger and electromagnetic appliance. Oscillator drive is made in form of air motor. EFFECT: higher efficiency. 6 cl, 3 dwg
