Manually operated apparatus for driving a member such as a tool or fastening element along a drive axis into a receiving material including a manually operated device for driving the member along the drive axis into the receiving material and means attached to said device for providing a visual indication of the angular disposition of the drive axis of the member relative to the surface of the receiving material into which it is being driven for positioning the member perpendicularly to the surface of the receiving material, wherein the improvement comprises a base arranged to be supported on the surface of the receiving material adjacent the location at which the member is to be driven into the receiving material, means attached to said device and connected to said base for affording an indication of the angular disposition of the drive axis of the member being driven by said device relative to the surface of the receiving material into which it is to be driven, said means being pivotally supported on said base for affording the visual indication of the angular disposition of the drive axis and for positioning the drive axis perpendicularly to the surface of the receiving material, said means comprises an axially elongated holder spaced laterally from and extending parallel with the drive axis of said device, said holder being pivotally mounted relative to said supporting base and being slidably displaceable in the axial direction relative to said device, each of said supporting base and said holder being coextensive and extending in the axial direction of the drive axis of said device, each of said supporting base and said holder having a forward end facing in the direction in which a member is driven into the receiving material and a rearward end facing in the opposite direction, said supporting base and holder each having swivel bearing surfaces in contact with one another and located adjacent the forward end of each, and the rearward end of said supporting base and of said holder each terminate in approximately the same plane extending transversely of the drive axis of said device.
