Abstract
A borehole mapping tool may include a probe casing having first and second ends that is sized to receive at least one location probe. An outer casing sized to be closely received by a borehole surrounds the probe casing so that an interior space is defined therebetween. A first end cap is mounted to a first end of the outer casing so that the first end of the probe casing extends beyond the first end cap. A second end cap is mounted to a second end of the outer casing so that the second end of the probe casing extends beyond the second end cap.
