just how good is this 7000 - going HOT with gpx and 7000, by steve herschbach - update

Post  kevlorraine2 on Wed Jun 07, 2017 5:30 pm

hi all, i was out yesterday with the 7000 and got blown away with what happened -----

i went to a well know, flogged to death, spot where i had previously found small nugs up to 1.5grams at various depths down to 12 inches.
but the soil profile meant there was no obvious "bottom".

as i had read the may gold gem and treasure mag with the story at page 6, and got  intrigued with the operators useing volume at 18 while in difficult mode, i was interested in seeing what happened when i tried useing  high volume in normal mode.  i use normal all the time and put up with the unstable interference, which i keep under a degree of control with regular pumping of the coil.

well blow me away.  the hotspot where i have found nugs up to one and a half grammes and down up to 12 inches.  produced again.
in a area of only four square meters i got a .4grammer, straight up, down a measured 15 inches. useing these settings --- high yield, normal, sensitivity 19, volume 18, maximum volume 14,  smoothing off, tone for me is always 74, threshold at 23 (or with bogene at 1, it doesnt seem to make much difference).

so it had proved the story in GGAT magazine.  i had to sit and think about this for awhile. then with my broad grin under control i had another crack at it, and only 2 feet away, right next to a filled in hole of mine, i eventually pulled out the biggest nugget of the spot of 2.25grams, down a whopping 18inches.
the intereference noise could only be described as "unbearable", but what the heck, i knew there was gold under my feet, and with much pumping of the coil, i was able to identify a slight wavering of the threshold. i couldnt be sure they were  targets until i was down 4 to 6 inches.  confirming -  it was a simple matter of lowering the volume to 14, which gave me an identifible  target sound.

in a three hour session, that totally wore me out in that two by two meter area i pulled out 6 pieces of rough gold (reefie stuff, no quartz).  
the 2.25 was followed by a .2 down about 6 inches, and a .6 and .8, both down over a foot.  total of 4.25grammes in a totally worn out spot, i thought. two tree root responses, and a couple of ground noises and hot rocks, kept me quessing.

WOW, talk about abusing a beautiful machine and getting results, but as JP is on record as saying ---- DONT BE AFRAID TO EXPERIEMENT ... kev

P.S. thank you macol and missus for your story in GGAT at page 6, may issue.

Good story, and interesting. Have just the spot to try that out.

Cheers Peter.

My experience yesterday, Last day to detect for this trip. Found a patch in an area no bigger than my 14ft caravan, got 34 nuggies from it. When the nuggies dried up I thought, What about giving normal a go on the patch, Straight away I got a signal, switched back to HY/D and no response, Back to normal and a good clear dig me signal, About 6" down out pops a 0.4g nuggie, Got another 7 nuggies, checked HY/D with them all, 5 of them not hearable in HY/D until I scrapped of some ground. 1 was just questionable knowing a signal was there and 1 I just plain missed, Total of 42 nuggies from a small area weighing in at 26.7g, What a way to finish the trip. Biggest being 6g and smallest being 0.1g.  Moral of the story, Try normal more often.  P.S. Not finished with this particular patch, re-camouflaged it for next time
Must add : Using normal in this particular spot worked brilliantly, The ground liked normal, No extra noise just signals booming through. Made me think how lucky are those that can use normal all the time. Moved about 20 metres away from the patch and Normal was very hard work to use ( Squealing at every movement and in some spots like a relic detector in all metal mode in a trashy area ) Going to do a lot more experimenting with normal from now on !

Thanks kevlorriane2 for posting this up ( Will try the pumping to calm the "Normal" savage beast )

Must get the GG&T Mag And read the article.

Cheers
Ashley

was out again today and came across a half grammer about 6 inches down. Very Happy it was a new spot and my method of trying to turn it into a patch means circiling it with ever increasing radius. nothing turned up Crying or Very sad
BUT remembering my recent experience of abusing the 7000 by maxing out the volume, i changed my regular volume of 14 to 18, with the following settings --- high yield, normal, no smoothing, and lots of pumping of the coil, and running the coil just above the heavier grass tufts as they give a false signal. the other setting that i have adjusted is the maximum volume, i used to run it at 10 or 12, but got sick of the continueous noises so i wacked it down to 6 and left it there. Twisted Evil
unbelieveable change What a Face i found another five nuggets all down over a foot and the deepest being at 17 inches, a 3.25grammer. Very Happy
the others were a 2.25g, about 15 inches down a .9g, .8g, and a .6g affraid made me wonder about all those isolated nuggets i have jagged, and nothing else in sight?
during this episode i managed to contain myself enough to do some testing in difficult, it was an abject failure, couldnt hear a damn thing with it. i managed to pick up one of the signals when down about four inches, but only when i turned the volume up to 18, at 12 there was no suggestion of anything.
downside of my maxing everything out is the need to check out every suspicious signal, most turned out to be hot rocks, which were easy to kick aside, except for the occasional deep (up to 8 inches down) hot rock, bummer. and way to many hot earth signals that you have to sink your pick into before the signal disappears (takes me way back to the gp extreme with a mono coil on. .... come to think of it, thats exactly how my 7000 performs, but with much better capacity to pick up deep targets in high yield).
am a happy but buggered chappy for todays effort ... kev Very Happy Very Happy Very Happy

Good result there Kev, Congats, Cant wait to get back in the goldfield and do some more testing/trying different settings with the Normal mode.

Good one Kev, I could have a spot just like that to try your settings out on. May I ask what sensitivity are you running with these settings?
The spot I want to go back to also has lots of small slivers of steel, were it must have been pushed with a machine I think. But I have managed a small bit and a 15g bit, so I think it's worth spending
more time on and trying different settings.  Cheers Peter.

peter, sorry mate, forgot to quote the sensitivity at 19, i most always keep it there full time. i cannot understand why people who run their machine extremely quiet, mostely in difficult with smoothing on, dont increase the sens. a simple test will show the much increased depth achieved? ... kev

In regards to this story in the GGAT that you refer too then what macol and missus neglected to say in their article for the results with the 7000 was the ground was heavily raked.

yes crowbar, i have heard that when they are on a patch they heavily rake the whole area. i call this "gardening", i come across this quite regularly in the bush. i dont do that, i rely on increasing the sensitivity, and volume, in conjunction with slowing my sweep, never touching the ground, pumping the coil to elimate all but the current spot being checked out. gardeners are a smaller version of commercial detectors with a big yella machine to take off the topsoil.

i see there is another upgrade to the 7000, my reading the info tells me it is all about keeping the machine quiet, which has been the approach for several years, but as they say, at the expense of sensitivity. so for me it might be benefitial for patch hunting, will see how it works ... kev

just how good is this 7000 update

Post  xmas tree on Wed Jul 12, 2017 6:06 pm

Hi KL2. you mentioned your settings of regular volume of 14 and max volume of 10/12, now 6. can you tell me which volume is which? Is the top volume regular and the bottom max volume? I'm trying your settings but am stuck on which volume is which, so i started with both of them on 18,which was really noisy,but i got 6 real deep sub grammers. that was 6 days ago and my ears are still ringing! xmas tree.

One is called "Target Volume" and the other is called "Volume Limit"

I think kevlorraine2 has the target volume at 18 and the volume limit at 14

thanks davegold , yes xmas tree, target volume is high for the very reason you want to hear those just hearable signals, but max volume is kept low to prevent your hearing from being damaged when you hit that unexpected hunk of tin or metal and has your hearing ringing till christmas Very Happy.

glad to hear you unearthed some deep small nuggies, well done ... kev

been out again over last two days and scored again useing 18 target volume with max volume set at 6. ---

yesterday in high yield, normal, target volume 12 and max volume 6 and useing the new ground smoothing mode turned on, i got a .6gram down six inches and followed with a .4 soon after, but then followed a hour or so of frustration dealing with all the rotten tin on the surface and some buried pieces of rubbish so gave it away.

went back today to same spot because i wanted to try, and see if by turning the volume up to 18 from 12, and only checking out any low, in the ground, noise, and disregarding all the loud surface tin rubbish, i might be able to pick up a nugget down deeper.
i got a .22 bullet down about 15 inches, then scored a .1gram piece of gold down two inches. that was followed by a inch square piece of tin down over a foot (thought i was onto a good one there) then i got a low-in the ground- response that ended up being a .6gram gold piece down a foot. Very Happy .... turned around and got a screamer in my ear, was gunna walk away from it, but my brain analised the noise as - different - so i turned the target volume down to 12 and sure enough it sounded sweet like shallow gold, it was a .4gram sunbaker, Shocked what i thought, foot down on one side and a sunbaker on the other side. bugger, how many of those other loud noises are shallow gold?????.

back on target volume at 18, i found another .1gram down two inches.

that will do, for a couple of hours workout, getting too complicated so i gave it away.

all the above in a area less than 7 by 7 meters, with hundreds of loud rubbish noises, couple of shot pellets and several root false signals, but thankfully no hot rocks or ground noises.

summary .... hard work for 1.2grams, a carton of grog Q11 , in very difficult soil, but proved again the worth of tackling it head on to prove that this 7000 has got to be the best machine i have ever used. thanks minelab ... kev

g'day all, a mate pointed me to a link by steve herchbach of navada us detector prospecting forum, who did a really good job of explaining what happens when you - ground balance - both GPX and 7000 minelab machines.

he clearly explains, much better than i could have done, the advantages of "going hot" to clean up a known gold hotspot.
a really good read to better understand your detector.

heres the link (thanks peter) ... kev
