A method and device for streamlining navigation from a point to a visual point of interest by combining the necessary items into a single device incorporating an optical finder such as binoculars which incorporates an optical display into the viewfinder, a rangefinder, GPS, compass, altimeter, inclinometer, microprocessor and memory. The carbon dioxide sensor can include a gate-less field effect transistor including a synthetic, quasi-intrinsic, hydrogen-passivated, single-crystal diamond layer exhibiting a 2-dimension hole gas effect, and a sensing layer comprising both a polymer and a hygroscopic material deposited onto a surface of the gate-less field effect transistor. The method further including storing the logical address and the hardware address in a memory unit after the allocating information has been performed. The wax emulsion can be made by any process for preparing emulsions used by those skilled in the art such as typical homogenization methods.
