A production logging tool for use in deviated wellbores is provided having an elongate tool body and an elongate sensor probe that is capable of lateral movement relative to the tool body. The sensor probe is connected to the tool body by a mechanism serving to deploy the sensor probe such that it is oriented across the wellbore. The tool body has a defined weight and the probe has a weight less than the defined weight, thus causing gravity induced orientation of the sensor probe so as to extend from top to bottom of the fluid passage for sensing all phases of the fluid present therein. The sensor probe is typically of elongate configuration and may support a single elongate sensor or a plurality of independent similar or dissimilar sensors arranged in spaced relation along the length of the probe. Orientation of the sensor probe across the borehole is accomplished mechanically by coil or leaf springs or by a hydraulically or pneumatically powered mechanism or by an electric motor driven mechanism.
