Hello!! Does anyone on here also have an explorer 2? I was just wondering what the difference is between the 2? The coils are interchangeable if I am correct in what I am reading. I was also curious about the difficulty of this detector for a new user. My son wants a minelab but does not put the time in to learn an explorer so I said maybe the quatro would be good, we mostly hunt the dirt but want a machine that can perform on the beach also. Any help is greatly appreciated. Good Luck!!
