Used when the natural gamma log is required. This tools
slim design permits logging in small diameter boreholes and
through steel or PVC drill pipe of 2 inch inside diameter or
larger. The sensor is located near the bottom of the tool to
permit data acquisition near the total depth of the borehole.
This tool can also be used with a spacer and gamma source to
record 4 p density.
