Darn it Dave!!  I’m going to have to read that bloody manual again!  ?

NE,

  I youtube it, to learn the different settings, to me visually watching is much better than a manual, kind of like having your own personal tutor, I just wish it was with some DD's..... ??

Both Gold 1 and Gold 2 are single tone VCO audio only. You can set that single tone's base pitch anywhere on the Tone 1 pitch scale. I run my kind of in the middle of the scale. I use the threshold tone which can also be set at any pitch. I set it an octave lower so I don't get the target tone and threshold tone confused. So you can have two different pitches at the same time but one is the target tone which modulates with the size and depth of the target and the other continuous tone is the threshold tone that drops out if anything discriminated is detected. You can also set volume levels independently for the target tone and threshold tone which is really nice. Like Phrunt, I have to use a little iron disc like -9, -8 and -7 where I hunt due to an abundance of hot rocks. Its either discriminate or go nuts in my case. I don't want to go nuts in the middle of nowhere......

Awesome finds, Phrunt!!!!!

Jeff,

  Yes your right, sorry for the error NE, your right,  gold mode only has the 1 tone VCO ...

Is there a setting on the 4500 where these don't get a response?  

I also wonder what a smooth threshold on a GPX sounds like.  Yours is sounding a little wavery like what I get often on the QED.  I am wanting it much smoother.  It's interesting to hear if this is considered a 'stable' GPX threshold. 

Congrats on the PB - always nice to get one over a gram  ?

I doubt my GPX would be considered smooth there but it's how I like to run it when I can get away with it, that's maximum sensitivity with audio in it's boost mode and sensitive extra, it's basically running the GPX flat out is my understanding.  I can get away with those settings in any places without power lines and when using them opens me up to finding 0.X gram size bits of gold and sometimes smaller..  The downside is the shotgun pellets you start to dig.  In powerline areas I have to drop my gain to between 9 and 12 and then I start to lose sensitivity to tiny gold.  A majority of the GPX gold I've found is in those settings.

I also have one of the first generation Australian made GPX's which I believe are a bit more ratty than the modern ones.

I would like GPX users past and present to comment on that threshold to see if I'm hindering myself running it so hot like that.

I had the audio very loud in the video as I turned my SP01 enhancer up to full volume to make sure it could be heard in the video properly.

I've tried every setting, I can't get rid of the hot rocks.  Changing coil is my next step in trying to tame them, maybe the NF Evo is just too sensitive so I'll try my Coiltek Joey or the stock 11".

Nice Nuggets you got there Simon...It looks like you are hunting tailing piles? If so do you have any idea how the old timers might have missed nuggets of that size? Do you know what methods they might have been using at that area ?

strick

JW would be the best to answer this question strick but the biggest nugget wasn't in a tailings pile, it was in a very unlikely spot which is why I found it, the tailings piles have already be cleaned out by JW and others, they wouldn't miss a big one like that ?

Hi there strick. I will take Simon's lead here & answer on his behalf. Naturally these gully workings go back to the initial gold rush days & for this location was 1862-63. So the first method was just all by hand. Turning the floor of the gully over by pick, shovel & wheelbarrow from one side to the other. Diverting the creek in the process. Then came ground sluicing to work higher up the banks & spurs. You will notice in Simon's 3rd pic a couple of horizontal lines cut into the hillside. These where water races & they are on both sides of this valley picking up what ever water they could from little side creeks. The material we are finding the gold in is from virgin ground that they didn't sluice away. You can tell by the look of the material itself that it hasn't been sorted by water & has all the natural fine gravels & silts undisturbed & mixed in still. The slope of the ground gives the impression that they are piles but that is just where the old timers stopped. Probably because they couldn't get their water up to that height or they thought it not worth their while to do so. Their method of sluicing was ground sluicing & not the high pressure monitors. Other gold I am finding is what is still jammed up down in the schist bed rock cracks & crevices that the old timers water didn't wash out & they didn't see but their sluicing took away the over burden down to the bed rock. God bless them.

This little coil is blowing me away with the gold it is finding me as I know how many times I have been over these grounds with my GP 3000 & 4500 with many different coils & the Zed with the ML 14. To be fair to the ML 14 coil there are some places that I just couldn't easily get that coil into, but they weren't many. I was still in for a few surprises with this little coil verses the ML 14. But that is my post yet to come. Cheers

Good luck out there

      Pretty much done for this year.  We've had snow twice already and it's hitting the teens at night.  Last season I got 106 bits for just under an ounce and this year I only detected 40 bits for just over an ounce so an improvement over my 1st season!  18 bits from Montana and 22 bits from Idaho.  FULL DISCLOSURE:  1 gram of the tiniest bits came from crack scratching/panning in the creek.  I had fun and met some locals from Helena area (BIG help) and that helped me stumble onto the two bigger pieces (25g/4.5g) that saved my season. As long as I can improve weight at the end of season over the last I've reached the main goal.
      good luck guys......

      This summer i had a chance to camp and hunt for a day, and i had some luck when i turned up this little slab just hanging out in a small depression in the bedrock.  .6gram

      Currently camped on the job in central Vic where comms are difficult, but here's a progress report.
      Been at it for a couple of weeks (I think ) but there are some results to report. I've been working solo a lot of the time but also with Reg when he's not too busy.
      We started off testing the new Detech 32" coplanar concentric which Stinky Pete kindly loaned us for a few days. What a coil!
      Although we didn't manage to put it over any deep gold, it's easily the deepest seeking coil we have ever used, yet sensitive to small targets as well. I'm ordering an 18" to 20" model as soon as they become available. Howard is busy planning mods to the QED so it can run them as well.
      I'm pretty excited about these coils. My friend Tony has been winding and using them for years with great prospecting success. Needless to say, he isn't interested in owning a "Z"
      Hang onto your GPX's folks, they're about to penetrate previously unreached depths!
      Some of the properties we've been prospecting are familiar and some are new. Always a buzz to finally get onto new ground after meeting with the "Cocky" and negotiating a deal. In some cases the ground has been detected before by others, but with careful gridding we always manage more. On one property we worked yesterday a previously detected patch yielded an additional ounce and a half in chunky colours (young blokes we were told) Perhaps they were ignoring screamers, but we're not complaining
      First up, my solo tally so far. largest piece (front) over half an oz. All found with QED PL2:

      - and our shared tally to be eventually split 50/50 . Again, largest piece (front) over half an oz detected by Reg:

      All gold located in patches on eroded Tertiary leads. Some pieces still have traces of the cement matrix they eroded out from.
      A general view of one of the Tertiary patches with Reg's young foxy "Boo"  photobombing. Reg in the distance:

      Posted elsewhere on this forum, my two largest pieces, found under 500kv powerlines:

      A 400mm dig for a 5 grammer. I love that 18" Elite, it even centered shallow flyshite that doesn't register on my scales:

      That's all for now. To be continued - - -

      Had an outing with a good friend to a Local creek yesterday. We dug a huge hole and moved some big boulders and found the 1.3g right at the start of the process. Diligent detecting elsewhere in the creek produced the other two. The 1.7g was right at the start of a crevice that seems to run under a virgin bank... Might dig that out some time but there are some fridge size boulders in the way. Cheers for the fun day out buddy.
