laser rangefinders
I got my Alpha Geophysics email update yesterday, didn't dig deep enough into cyberspace to find that one but did see hand-held units, the cheapest one about $500.
They're laser rangefinders, sort of an optical radar. The fancier models include surveying features built-in. I suppose this fancy unit linked by Nicolas includes semiautomated mapping support.
These are professional instruments that actually work. Therefore of no interest to LRL fans.
