My wife & I bought our 1st detector (GP3500) in 2005 and have been hooked ever since. We are a couple of grey nomads and detect in WA each year with varying degrees of success. We also find time to detect in Vic for 3 weeks each year but struggle to find very much. We are looking forward to trying our luck in the Northern Territory for the first time this year and would welcome any advice. Hope we meet up with some members on our travels. Happy swinging ..........
