Claim:
A multiplexer comprising: a body to be carried by a surveyor; more than one survey sensor connected to the body, and each of the survey sensor comprising: at least one location sensor for sensing the relative location of the body, the exact location, or both; a pipeline sensor for sensing the depth of a buried pipeline; a receiver incorporated into the body for receiving an incoming data stream from each survey sensor and converting the data streams into a single output stream; a filter for filtering the incoming data streams, prior to converting the data streams into a single output stream, to reduce a volume of the incoming data streams, the filter selecting data strings based on pre-selected threshold ranges from each survey sensor data stream, and filtering out a remainder; a power source and power regulator incorporated into the body, and the power source powering each survey sensor via the power regulator; an integral time clock incorporated into the body, the integral time clock incrementally time stamping each incoming data string; and a data output connected to a portable electronic device.
