Metal Detectors in auction lockers

Has anyone ever gotten a metal detector in a storage locker?  This would be the good ones by Whites, etc, not the $30 Radio Shack variety. 

I haven't found one yet but I always hope to.  I used to be an avid treasure hunter.  I have had all kinds of MDs but my favorite was the Minelab Excalibur  I used in the lake at various swimming holes (found a lot of gold).  If I see even part of one sticking out in a unit I will recognize it.  Hopefully the average Joe won't know what it is or what it's worth.  They sell for about $1400 new and around 800 used.  Also using the deductive reasoning only a storage unit buyer can appreciate  maybe in some of the boxes there will be some of the gold the owner found with it.

I'd like to find one too! Around here, there are tons of Civil War artifacts in the ground. I just don't want to shell out the big bucks to really effectively look for them.
