ABSTRACT OF THE DISCLOSURE A portable shear-vane penetrometer is described, having a tubular body, a shaft supported over a portion thereof in said body, and a coil spring and handle. The coil spring is adapted to enable measure- ment against the predetermined characteristics of that spring of both the force needed to cause the shaft to penetrate the soil and the torque needed to enable the shaft to be rotated in the soil. First and second measuring means are provided, respectively, on the tubular body, and the handle to provide a readout of the force for penetration; and the torque for rotation.
