Okay I'm new to everything, this forum and metal detecting. My new MXT Pro should be here today and I feel a long learning curve coming. I live in Colorado and am assuming Colorado has high mineral soil. Is there anyone on here with experience on this in Colorado? Next - I've been doing some reading on coils, about all I think I've figured out is that the stock coil is probably not the one I need to use here. Any opinions on the coil I should start out with? I'll be looking for coins/relics and occasionally trying my hand at some prospecting. I would welcome any other words of wisdom.
