Just purchased a second hand X-TERRA 70, [hasn't arrived yet ] to compliment my EXPLORER SE. I have never been gold detecting before, and was wondering what sort of sound you get in relation to Australian $1 - $2 coins. I spoke to BT quite a long time ago, and he thought the Explorer was not good for gold, so it has taken a lot of walking to find enough money to buy the X-Terra, I hope this thing is as good as he reckons it is
