The five cent piece is the smallest coin in circulation in Australia now and most of my photos where I have used a coin for scale I have used a 5 cent and the creature on the coin is the echidna.  In the 7 years I have lived in Victoria I have only ever seen maybe a dozen echidnas, but what makes this guy so special is this morning he was in my back yard.???         The half grammer came from Cockatoo Bush a couple of years ago, but I have seen way more half grammers than echidnas. ? Dave

Mac, never having seen a bear, moose or wolf, and never likley to, I found that a very informative post. Thanks

Steve I have a reasonably quick internet connection but not lightining fast.   Because you asked, I`ve noticed no difference.  I`ve always thought the site ran fine.       Dave

A very nice piece Norm. Well done ?

Thats not a yes/no/rarely answer for me.   Spoked coils I always use a scoop. I never use a scoop with the 7000 and 14" coil, I just push the dirt around on top of the coil till I locate the target. With the 2300 if its a nice loud signal I push the dirt around on the coil, if it`s a small target with the 2300, I use the scoop.      Steve am I allowed to select all three answers?  ?

Hey JW.   Over the years I could have won a lot of money with this speci. Everybody that has ever seen it has informed me "of course I`m going to be able to hear that" and they are stunned when they can`t hear it.  One of them even asked me was I sure it was gold ?  I don`t think he even believed me when I showed him that the 2300 and the 7000 could hear it clearly ???       And mate I laughed when I read your suggestion there was one sure way to see how much gold there is in it. . While it`s mine, that aint ever going to happen. ? cheers Dave

I will most certainly bring it along next time you want to go for a prospect as I'm very interested to see if your GPZ will see it as I'm completely puzzled why my GPX can't see it, no matter how hard I try, what settings or coil I use, it's invisible even touching the coil.

I`ve got a speci I found maybe 30 yrs ago with a Whites GoldMaster that sg`s at 13 grams gold, I don`t believe there`s 13 grams in it but that`s what it sg`s at. Even though there is gold clearley visible, my GPX4000 cannot hear it, a gpx4500 cannot hear it and the GPX5000 can just barely hear it with a 8" Commander.  None of the new flat wound coils on the 5000 can hear it.   Both my 7000 and 2300 can hear it at 6 or 7 inches.     I expect JW will be able to hear your nugget no worries with his 7000.       cheers Dave

Doesn't make sense to me.  It would seem logical that iit can find small stuff  big stuff should be easy?

This is my understanding of why one detector will get bigger deeper gold over another.
   A detector transmits a signal into the ground and then switches  to receive the signal coming back to the detector. Think of a opening and closing gate.  The longer the gate is open the further into the ground the signal will travel before the detector switches over to receive the signal. With the likes of the sdc2300 the gate opens and closes very quickly, doesn`t travel into the ground very far, so with the high frequency switching, it will find way more small gold than most other PI`s.  The slower switching detectors, the signal goes way deeper into the ground where there might be a bigger deeper bit.
   I hope I`ve got that right. Please correct me if I am wrong. Dave

Thanks mate. I was very happy to get it, it`s always satisfying for me to get those super small ones.  I took the photo with a 150 power usb microscope. cheers

And I mean little.      The 2300 could just barely hear it and I had it the scoop 4 or 5 times before I could hear it in the scoop ?  I`d say it`s a 0.05 g max. Dave

For the first time in many months I fired up the 2300.   The first spot I went to was birdshot alley and I only lasted there about 30 mins.   I then went to a spot where I knew there wasn`t a heap of birdshot and I got these 15 from digging about 30 targets.     The smallest 5 here weigh 0.14g and the whole lot goes 0.85g. This lot took me 6 or 7 hours over two days.   It stll amazes me what the 2300 is capable of finding.  Dave  

I have noticed since I have been detecting in semi auto tracking, at the start of the day when I drop the ferrite ring on the ground, I can never hear the ferrite, but I do the thing with the quick track button anyway.  

My question is:    Once I have set up the detector to the ferrite ring in semi auto tracking, if I NEVER touch the quick track button ever again, and never take the detector out of semi auto, do I ever have to use the ferrite ring again?

  It seems to me if you dont touch the quick track button in semi auto the detector always has the correct ferrite balance regardless of ground conditions.  Dave

While the target was still in the ground undisturbed by my retrieval the signal was always there, did not fade or balance out. Still very faint due to the size, but on moving the target have lost the signal completely. Nothing, nada....having to use the either the GB2 or the GM 1000, depending which one I grab, to find the target & finally retrieve it. The signal has always been a tiny bit of gold that the Zed picked up on initially but once moved was lost. I put this down to the "halo" effect & not balancing the signal out by being in Auto GB. Like I said, while the target was undisturbed in the ground the signal was always there no matter how many times I swept over it. Not until it moved was it gone. Anybody have their own thoughts on this? Thanks.

Hey JW. I`ve always put this down to when you move the target you change what the detector sees.  Maybe when it was undisturbed the detector could see a bigger or smaller cross sectional area.  Most of the time when this happens, I find if I move the dirt around that came out of the hole I can re locate it.   I`ve also found when chasing those sub sub grammers that I can no longer hear, turning Target Volume up to max helps re locate them. I generally run a pretty low Target Volume.  Dave

What a amazing array. Well done mate

I haven`t been putting up any finds lately because I`ve been in a bit of a drought but I like posting pictures of gold so here is a couple of quartz specis I found about 200 yards and 4 years apart out at Moliagul.   The one on the right total weight 980 grams with about ½ gram of gold and the other 250 grams with about 1 gram gold.   Dave

Hey Hispana.   I`ve got one and used it with my 5000.   I found it to be a increadably stable coil with good sensitivity.   Back in those days it used to feel like I was swinging a barbeque plate because of the weight,  but I`m guessing if I were to use it today it would feel light compared to the 19" coil on the 7000. Dave

Congratulations oneguy. That`s a terrific first nugget

I bought another Michigan copper nugget the other day.      I love this kind of stuff.      This one goes 235 grams.  7½ ounces feels really nice in your hand

Which way the nugget is laying in the ground, the shape of the nugget, soil conditions, even the purity of the nugget will all effect how deep you will get a particular piece of gold. Dave

I was going through my computer looking at different stuff that I had forgotten I had and I came across this shortcut to the archives of Gold Net Australia.   Gold Net Australia Online went from 1999 to 2002 and remarkably, it`s still there.  Probably not of great interest to people in the States, but if you enjoy reading about coil developement from 20 yrs ago, or accommodation, or a review of the GP Extreme,  or divining rods, or storys of big finds or just pictures of beaut nuggets, there might be something here of interest.

I could just see me kicking the horn all night long with that thing 

Mate that`s easy fixed.          Turn around the other way, then you`ll only kick out the back window

A very clever idea for if you want to get away for a quick couple of days detecting without towing a van.

I`ve been going back and re reading all the stuff I can find that JP has written about the 7000.  One of his articles about going for bigger stuff  he recommends General/ Difficult over High Yield/Difficult, and for the last few weeks that`s the setting I`ve been using.  Still not setting the world on fire but got a funny one yesterday.  This piece came through as that lovely electronic warbly signal I like and before I disturbed the ground I tried High Yield and could just barely hear it. Switched back to General and could hear it no probs.    It only goes 0.35 g and it amazed me that General would get such a small piece better than High Yield. It was down about 8 or 9" range.  This is one of the articles where JP mentions General over High Yield https://www.minelab.com/anz/go-minelabbing/treasure-talk/gpz-19-compared-to-gpz-14-nugget-dig

My bad.  No detecting today because there is a huge wind blowing, but I just went out and turned on my detector,  turned on the first WM12, got sound, turned it off , turned on 2nd WM12, no sound, turned on first again and got sound out of the second.    Sorry about that, I assumed they worked independently because I`ve never noticed otherwise.   I`m not real bright. Dave

Hey Goldscreamer
I run twin WM12`s and they run independently of each other. I don`t know for sure but I`m guessing you would go into settings and select "Connect Additional WM 12" and then set up one of the WM12`s from there.   Dave
