Detection of magnetic and non-magnetic metals Superior detection depth Accurate Localisation Total immunity to terrestrial magnetic anomalies Static and dynamic detection, independent of the speed of transit of the detector head Lightweight, ergonomic search probe for maximum comfort Completely digital electronics, with in-the-field program memory upgrade capability Extremely high level of electrical and mechanical reliability Ease of use with minimum training time required Operation monitored by a microcomputer-controlled autodiagnostic system with audible warnings signals The CEIA MIL-D1/DS Metal Detector is an active EMI detector based on transmission of an alternating, low-frequency magnetic field and on the variations introduced into this field by buried metal masses. The detector consists of a telescopic pole with a central section in aluminium and fibreglass extensions. The two probe-antennae which act as transmitter and receiver of the magnetic field are mounted at the ends of the extensions. Detection signals are provided by an audible tone and an LCD located on the front panel of the control unit. The most significant features of the MIL D1/DS are the following: its high sensitivity, useful for detecting metal masses at depth; its capacity for discrimination between surface metal masses and those of interest; its compensation for mineralized soils and total immunity to the effects of the terrestrial magnetic field; the high stability of its detection system, which shows no drift over time or with variations in environmental conditions; its intrinsic reliability and extremely high resistance to shock and mechanical stress, essential requirements for a long operating life.
