I've been gold prospecting and diving on gold dredges for quite a few years. However, I am I'm brand new (Cherry) to gold detecting with a machine. I have started out with a Gold Monster 1000 which is pretty straight forward. I also have a Minelab CTX 3030. When I'm looking for Gold nuggets with the CTX 3030, do you use Coin, Beach, Relic or Silver? Thanks .... ~ Joe
