Primarily found in oil, gas and mining applications, borehole cameras are meant to cover long distances. Borehole cameras usually come on a spool or a reel, as insertion tube or insertion probe lengths can exceed hundreds of meters. Depending on the specific inspection application, borehole cameras can be used on mines, oil wells, water wells, pipelines, and even sewer lines.
