hi , everyone.i m a french guy , i came in australia one and a half year ago .I have begun to think about prospecting seriously 6 month ago and since i m taking some informations like reading books what material i should use and all stuffs i can find on the web. i plan to begin this adventure in october november. Quickly i thought that i should use a mine lab detector , the 4500 gpx .and then i have seen the 5000what i have understood is that for high mineralized soil the dd technology is the best but also that you need a bigger coil for deep target and smaller one for the surface ones . is that correct? anyway that topic is really good for me , i heard as well about the ATX and actually the price was very attractive but i was still focus on the mine lab product and then i saw those videos on you tube which compares both of it.To be honest i m not even a beginner but after watching it i was lost.So thanks for your point of view.
