Abstract: Methods and apparatus for a Dual Emission Non-Ferrous Metal Prospecting System are disclosed. One embodiment comprises methods and apparatus for finding metal deposits in the Earth, and then determining whether these metal deposits are ferrous or non-ferrous. One embodiment includes an Electromagnetic Quartz Penetrator. The Electromagnetic Quartz Penetrator includes a transmitter, a receiver, antennas and a first signal processor. One embodiment also includes an Omni-Directional H Field Metal Exciter and Sensor. The Omni-Directional H field exciter produces an output which has a spatial dissipation rate proportional to a factor of 1/r3, and, therefore, has a relatively short range compared to the Electromagnetic Plane.

Abstract: A portable communications device (PCD) for communications over a plurality of communication channels and a cross router for controlling one or more of the communication channels to be active. Typically, the plurality of communications channels includes a cellular channel, a satellite channel and a WiFi channel.
