1. A reduced length modular drill hole logging tool for use in the geological identification of requirements of a drill hole comprising:
a tool head;
a diameter and profile measurement system connected to the tool head, with a plurality of radially extendible and retractable caliper arms positioned about the system;
a gamma radiation detection system at least partially nested under the caliper arms, when retracted, of the diameter and profile measurement system;
one or more additional removable modules of geological data collecting sensors supported in a case configured to be received in the drill hole; and
a control module that communicates with the one or more modules and collects the geological data from the sensors, wherein said control module is housed within said tool head.
