%X The Suspension P-S Logging System is a velocity logging system based on the principles of unlocking type receivers and indirect excitation type sources. In Japan, this system is mainly applied to site investigations where the ground is of low velocity, for large scale building projects on land or undersea. The development of the Suspension P-S Logging System and its effectiveness in low velocity ground have been previously reported (Ogura et al. 1980; Yoshimura et al. 1982: Tanaka et al. 1984). This paper concerns our attempt to deal with the problems involved in improving the system's probe for application to high velocity ground.
