Just thought I would throw this out. Saw it posted on craigslist.
There's a person in St. Louis that lost a wedding band in their back yard and wants to rent a metal detector for 1/2 hour for $40.00. Probably better to just look for the fellows wedding band on your own for the $40.00.
Anyway, here's the ad - http://stlouis.craigslist.org/ele/2302659788.html
