The metal detectors are constantly changing. There are innovations, improvements, companies going out of business and new companies starting up. Anyone who wants to be active in the hobby probably should join the Metal Detector Club. There are a lot of them in larger cities. Minnesota has two clubs; one in the Twin cities area, and one in Rochester. At one time, there were four clubs in the state but the two smaller ones that folded up. By being in a club, you get ideas from people about where to hunt and most clubs have organized activities. Some clubs have a small hunt almost every month where they go to a park or beach somewhere and leaders of the club bury a couple of hundred coins and everybody pitches in 10 bucks and they all try to find those coins that were buried. There are larger hunts, I participated a couple of months ago in I hunt near Moline, Illinois, where over two days they buried something like 12,000 coins for 7-8 different hunts. To participate in that you have to pay about $140 for two days, but you are going to find old silver coins, may be one or two gold coins, or tokens for a brand new metal detector. There were 127 people participating in that. You find out about activities like that from two sources: from being in a treasure hunters' club or by buying one of the two treasure magazines. If you are a computer nut, you can search the Internet and find out a lot of information. There are a few people who only participate in those hunts. If they are to go out hunting, they want to find something good, so they pay their $50 or $100 fee and they know they are going to come home with some good old coins.
