I have finally given in to a long-standing urge/desire and want to buy a detector. Can't afford a "top-of-the-line" machine, but would like to be able to effectively work the beaches and woods of Cape Cod, where I have recently moved (I have done my research and I am familiar with the prohibitions of the National Seashore). Can anyone recommend a good machine in the $100 - $400 range. Thanks in advance for your help.
