V350 - Interpex Ix1d

While there are 2D and 3D inversion packages available (like RES2DINV), remains relevant because: Speed: You can run an inversion in seconds.

MT forward modeling using plane wave or user-defined segmented wire sources. Interactive Editing interpex ix1d v350

: Directly type or paste data from external tools like Excel. Flat ASCII & USF : Import from standard flat ASCII files or the Universal Sounding Format (USF) Borehole Integration : A standout feature is the ability to import Borehole Resistivity Data While there are 2D and 3D inversion packages

Bottom line Interpex IX1D V3.50 remains a practical, technically sound choice for anyone committed to 1‑D geophysical sounding work: compact, feature‑complete for its niche, and dependable — especially when interpretive clarity and inversion control matter more than modern UI bells and whistles.
