Ahead of the first Mag Objects Finding Olympiad (MOFO), our Michael Glutting had planted 19 mag nails, close together, from 16d common nails to 2-3/4 inch Mag Spikes from ChrisNik, in an 18 x 12 feet land in front of our San Jose headquarters. The site had a great deal of ambient noise from a nearby freeway and construction work. Later we found that the land was also infested with several old junk nails.

Contestants were challenged to find the nails and identify their type from the signal strength.
