This report describes an instrument developed by the Bureau of Mines as an improved device for examining roof rock in bolt holes. The unit consists of a commercially available fiberoptic unit adapted for use as a flexible stratascope. Field testing in both metal and coal mines has shown the instrument can be easily transported and used by a single operator. The size and flexibility of the instrument eliminate the need for specially drilled holes.
