Oh - now I see there is a first post concerning the cache (btw. the main post from me also is above) - 20m is really fantastic!
Is the pistol you used the same system Geo found the mine a few weeks ago?
Hi Astrodetect,
infrared already uses a very short wavelenght between light and microwaves so I don't know what you exactly mean.
Could it be some of these LRLs are just simple EM-Field Meters? Using FETs and gold as electrode just because it has near same electrostatic attributes like air?

However at least the magnetic flux between the earth-caps is directional and the gravitation also.
btw. I wanna try out that: "ic burns near treasure"-circuit or schematic. Where can I find it?
