I new to your great forum and I will be purchasing my first detector. I live in Northern California and I will be using the detector mainly for gold prospecting. However, it would be nice if the detector could be used for coins/relics on an occasional basis. Any suggestions? I was thinking of a White's GMT. However, I am now leaning towards a PI unit, such as a MInelab or the Infinium LS. I also understand that White's will be releasing a new PI unit shortly. All suggestions would be greatly appreciated!
