Dolang Geophysical - Model W2Z 1CH -Wireless Sesmograph Logger

This logger allows - as the BISON did in the 80`s - to make seismic acquisitions in refraction and reflection using only a geophone and obtain a 24-channel SEG2 SEGY file. For MASW you must add a geophone and follow the dynamic pattern to have the 12 or 24 channels needed for post processing. Very low cost and so is the weight, all in one backpack.
