N2  - Historically, seismic refraction instrumentation has usually been equivalent to that which existed ten to twenty years previously in the seismic reflection industry. Accordingly, it is encouraging but not unexpected to see data acquisition units with stackers and digital recorders becoming more common. Twelve channel units have superseded single channel units as the most commonly purchased units.
