Overview
The TEM-4 is a single-channel magnetic field antenna developed for transient EM, CSAMT, and other EM survey configurations where crews need vertical or horizontal field measurements in a compact package. It can be used inside or outside the transmitting loop for transient work, and multiple units can be combined when more than one axis is required.
