Treasure hunting shows cause a rash influx of newbies to rush out and buy detectors thinking they are going to strike it rich. The vast majority of these newbies will have no regard for the code of ethics that true hobbyists follow religously. This in turn causes parks to close and private land owners to turn away would be hobbyists because of all the media attention. I see no positive outcome from these type shows for the hobby of metal detecting. Just MHO.
