My question is how much does one need to spend to get a decent detector ? Please don't respond with buy the most expensive that you can afford.Also which do you reccomend to stay away from ? Would like to purchase a decent one that you don't need to take night classes to learn.Some have told me that some are hard to figure out and use.My purpose I guess would be just general detecting In Minnesota (Winona) Also if anyone knows of places to detect in my area would also be helpful.Thanks in advance for your help !
