GEO2X geophysicists  are using refraction method since more than 20 years.

Landslides, groundwater prospecting and geotechnical problems are the most usual purpose of their investigations.

They are using powerful software:
WinSism;
SeisOpt2D;
Rayfract.

and the most accurate methods:
Intercept time;
ABC / Delay method;
GRM method;
Tomography;
Refraction Inversion.
