[QUOTE="Michael1986, post: 377725, member: 6299"] I recently purchased a second hand GPX 4500 and I'm hoping to get a bit of advice on the below questions. I've only been detecting about 5-6 times so apologies if the questions are a bit silly. What is the smallest size nugget that I should use as a test nugget before detecting? I have 4 very small pieces that are about .03 grams each that don't register with the machine when doing an air test. I'm using a 12" Evo Nugget Finder Mono Coil. Do I need a bigger test nugget or is it likely the problem is with my settings? I have tried factory default settings and some settings set by Coiltek in Maryborough and both haven't worked. If it's the settings can you recommend a company in VIC that offers great one on one training so I can learn to use the machine a bit better? I can run the machine quietly, even in high mineralisation and pickup tiny pieces of scrap over a foot deep but not picking up the 0.03 gram pieces of gold has me worried. Thanks guys and Merry Xmas!! [/QUOTE]
