The McSEIS-PS is designed mainly for the measurement of downhole PS well logging in combination with a Borehole Pick (Model-3315). When used with our special programs, it is possible to carry out its data analysis easily on a commercial laptop PC.
The Borehole Pick is used to measure the P wave and S wave velocities of the ground. It contains a 3-component geophone in which one component is for vertical and two components are for horizontal direction, and can be used even in a relatively small borehole (e.g. φ 56 mm) because of its compact design.
