I recently purchased this $15 hand held metal detector (i think intended for detecting wall studs and the sort) manufactured by Centech...I learned about it by simply doing a google search with: "cheap pin-pointer"...this yielded some metal detecting blog entries which spoke of this $15 unit sold by the Harbor Freight company...I was wondering if anyone had heard any feedback about it?..I have a $5 off promotion code if anyone is interested as well...Happy hunting!..
