Seismic prospecting is apt to increasing yearly and utilizing effectively for many geological surveys in civil engineering as one of the most popularized survey method. Recently, the measurement of S-wave velocities are taking in effect as a necessary to make a basic data of the dynamic properties of soil ground in predicting the behavior of the ground at the time of an earthquake. However, as though the seismic prospecting in the field of civil engineering become generalized, there are many problems unsolved on actual survey. Especially, the seismic prospectingare limited by the problems on the preservation of safety by using an explosive. On the other hand, it is impossible to carry on seismic prospecting in the urban area by high noise level and also unable to use any explosive compound. As one of the method to solve this problems, the data processing method called Enhancement and Stacking become the object of public attention in recent year. The existing several equipments were so large scale and expensive so far, but recently the inexpensive, easy handling, light weighted and small equipment is developed using a low-cost semiconductor memories and IC, which are produced by the most advanced electronics technology. In this paper, it is described a special features, utilization and prospecting samples of signal enhancement equipment called "McSeis", which is newly developed by OYO CORPORATION and Nimbus Instruments in U.S.A. Furthermore, refering an expansion of application in seismic prospecting by utilizing "McSeis" and present problems on "McSeis", it is introduced as an aid to contemplate development of geophysical prospecting in Civil Engineering in the future.
