Yeah, as I recall, the MYTH gun started out as able to detect a METH factory from a block away.
Finally, it dwindled down to having to plot out a small space on a wall, and then swabbing that space with alcohol, then transfer the swab to a
glass plate and scanning that, hoping that the SUDAFED vapors have not dissipated.
Just as well, because no Judge would give up a search warrant on the basis of that one block thing, or accept as evidence the swabbing.
Besides any Cop worth his meager pay would already KNOW where the METH houses are. Knowing and getting a Warrant is two different things.
