Is the Garrett ATX any good on WA gold fields ?

[QUOTE="christian1664, post: 255762, member: 7733"] Thanks everyone for your opinions and advice, looks like Garrett have shot themselves in the foot marketing the ATX as a "gold" machine for WA when all the evidence points to the fact its not. Would I use it on a beach ? without doubt for 90% of the beaches I work its outstanding the other 10% are so contaminated with iron you need a detector with good discrimination. Would I use it for relic hunting, no way, you will spend all day digging nails, horse shoes and the other 3000 years of Iron dross that has been lost over the years in the UK, my go to machine is the XP deus 3.2. How would it work on Australian relic sites, my thoughts (and these are only thoughts), are not well due to the extensive use of wriggly tin and canned goods, let me know if I'm wrong. One last point you may wish to look into, many times I've read the comment it finds lead shot so it should find gold!! sounds reasonable until you dig deeper lol Gold has a electrical conductivity of 44.2 and a resistance of 2.3 so its a good conductor and poor resistor lead has a conductivity of 4.7 (almost ten time worse than gold) and a resistance of 21.3 again ten times greater than gold, so lead is a poor conductor and good resistor. So gold and lead are almost direct opposite's when exposed to electrical current, gold should give a stronger signal than lead !! so what is going on with the ATX ? if it can find tiny lead shot why is it struggling with gold, me thinks it may be a programing issue rather than being a duff machine, might write to garrett with my thoughts [/QUOTE]
