Geotech's proprietary VTEM is the leading time-domain electromagnetic system in the world. The coincident, vertical dipole transmitter-receiver configuration provides a symmetric system response. Any asymmetry in the measured EM profile is due to the conductor dip, not the system or direction of flying. This allows for easy identification of the conductor location and for interpretation of the EM data. The low noise receiver, plus the high power transmitter yields a low noise system that has the best signal-to-noise ratio of any airborne survey system available commercially.
