Hi Augoldhunter, For a while you have promoting to newbies that VLF detectors are the go for gold. In Australia clearly VLF mds are not the go for our geology when hunting gold. . Only the GPX is winner in the gold horse race. To get the best out of a GPX using manual over ride and knowing the the right settings, takes a while to get use too. I have never used factory reset or auto tune. The most popular coil used is the 12 x 7 Nugget finder Elliptical Mono coil , light enough to use all day and easy to maneuver around scrubby ground. This coil clearly has far more advantages over the smaller 8x6 nugget finder. No problem at nailing a 10th of a gram at 55 mms. 14 inch coil doesnt give that much more and i would go for the next one up the 16 inch . I,m still running a 4500 gpx and at this stage have no want to up grade as the model is proven . Still with top range machine gold is thin and hard to find. Takes more than just a md to find gold.

I'm with you on that one Tinpan, I put in the hours, have a little success/fun with my VLF machines, but as you say, our geology makes them very hard to work with (in some areas) and you're right on the money, NOTHING! beats a GP-GPX hell even the older SD machines are still pulling gold... I really should start making videos of my hunts, so people understand the scale of what goes into finding the gold i find, so they understand (as I tried to explain above)
I go out seeking the likely "gold traps" clear overburden, detect the area, and occasionally get some nice color (colour for the Aussies reading this) 80-90% of my VLF work happens in, washes and dry creeks (if i can find them)
So many people overestimate these VLF machines, swear blind they go deep and find Oz's. Sadly in most cases ground conditions spoil your fun..
Now I'm not saying people won't have success with a good VLF in Australia.. I do very well with my Whites, and Fisher machines... However If I'm in WA or VIC gold fields the VLF isn't my first choice.
What am I saying?... Choose the detector for the job, KNOW THE JOB... Before you head out, be it Australia, US, Canada, etc... Learn about the area. (Large nuggets were found? How large? How deep? Hard rock mine? Alluvial/placer?
I haven't been into detecting for that long, I sure as hell don't know it all, but the few things I do know (that work for me) I'm more than happy to share..
Again: Tinpan, thanks for the coil suggestion. I've sourced myself a 12 x 7 nugget finder elliptical.. A friend with a 5000 has a 17 x 11" nuggetfinder dropped it by today, I'll take it out for a spin in a few weeks.. Sadly back to work for me
