New! Multi-Frequency Monopole-Dipole Configuration


The new Multi-Frequency, Monopole-Dipole Full Waveform Sonic tool is compatible with MGX II Portable Digital Logging Systems and will operate on single or multiconductor wirelines. The standard probe includes transmitter - receiver spacings of 3 & 4 feet. Customers can order probes with different spacings (metric or english) and can combine it with natural gamma (2SSB-1000)
