Hi, I'm new to metal detecting and have a budget of about $400. I'm looking for something useful for relic hunting around old farmsteads etc. I believe I've narrowed it down to the Coinmaster GT or the Gamma 6000 (which I found on Amazon for $429). I see a lot of information on the forums on the Delta 4000 and Coinmaster Pro but not much on the Gamma or GT. Thoughts?
