A bias unit having a support body in use to be integrated with a drilling assembly and rotatable therewith for drilling a borehole penetrating a geological formation. A pad is pivotally connected to the support body proximate to the leading edge of the pad. A spring-driven push rod is positioned and preloaded to engage the pad, proximate to the trailing edge of the pad, and to urge the pad outward from the support body to contact the borehole wall during drilling.
