Hello All, I read these notes with great interest, and would like to go down to BT's neck of the woods, and buy an XT70 with a 18.75 hz 10x5 elliptical coil and look for gold. But living on the Central Coast NSW its a bit far. I see the cost of these machines in the USA are quoted at $699. WHY do these machines cost $1200 here in Australia, when our $ is now worth 90% of the US $. It makes you wonder, and I feel we are being ripped off. When they bring out a 15" coil to do the beaches for these machines ,I will sell my Explorer SE and change to an XT70,and then I will have an excuse to go gold detecting. HH
