The 9074, 8074, 7074 and 6074 Three Arm Caliper logging tools,
are a three-arm caliper configuration used to measure the diameter
of the borehole. They can be used in both open and cased holes.
Natural Gamma and the casing collar locator are optionally available.
However, when configured with both the natural gamma and casing
collar locator the tool is slightly longer.
