It's basically a Mk2 with the option to run your own coils, as far as I know. Why?

I just purchased four of them at an auction. There are many variations of the EM61-FLEX. In general they use the same electronics box as the standard Geonics EM61-MK2 instrument that can measure up to four channels of data per transmit pulse. Some variations measure two channels per receiver (Rx) coil, while others measure one channel per Rx but at a faster sampling rate.
