Hi there ophirboy, Thanks for your report. So how did you go on the gold finds after 2 months of operating you GM1000. Didn't see any pics.:biggrin: Cheers

Good luck out there

Hi Kiwijw

This is the largest Iv,e found ,in amongst scattered quartz it is slightly water worn and rounded on top, I also have some quartz pieces that have given a positive result but I have not crushed them I  also have about 4 smaller pieces similar to what I have seen on the forum. The areas I detect have been heavily hit with sdc2300,s so you have to be persistent and lucky.

Same thing i have posted as  a review on the GM 1000 dont trust much that discrimination bar to it be rock soliddd !!

And still digg it up more and swich angle to make suree is still rock solid thenn . Just move one. !.

 

Thank you for your review ..

Hi ophirboy,Interesting report .Let me just say that I have looked on 3 continents on forums about testing of the Nokta Impact on goldfields and have found nothing.I posted one about the Impact on goldfields in Australia a month ago on an Australian forum and on this forum only last week, so I have been the first.I daresay you are also the first to file a report about the GM 1000 on a goldfield.Congratulations.We Aussies obviously like to live dangerously.My Nokta Impact is a real monster and very sensitive.Found a 0.1 gram of steel which gave a normal signal in all metal mode 4 inches deep I reckon it might have been a chip from a digging tool such as a crowbar.I am detecting in the Golden Triangle here in Victoria in the very high mineralisation such like you.I reckon I had some false signals in the hotter areas in the discrimination modes early on when I first started to use it.I have not bothered to find the optimum settings to get rid of the falsing on any disc. mode but I have some ideas on how to do it.I mainly use the all metal mode called GEN with the minimum disc.setting of 01 to listen to iron and hot rocks.So I get 2 tones,a low and high tone.It makes life a lot easier and I just dig up all the high tone signals.

Hi Mike .

Good to hear from another Aussie on the forum . I don't know a lot about the Nokta detector although a lot of people have mentioned them as one of the brands that led minelab to develop the GM 1000. A lot of members from the states seem to work in much lower mineralization and therefore there reports can lead you to believe that the detector sensitivity can be ramped up and give good results. Be cautious as our conditions can cause what some call fogging to the receiver circuit ( like headlights in fog) that can hide small targets if an unsuitably high sensitivity setting is used . Quite often a more conservative setting can give much better performance. this would certainly apply to the Golden triangle. It also makes your discriminator marginally usefull . As I said in the report , learning the machines strengths and weaknesses is vitally important to success , Good luck and I hope you do well down there.

Great reporting ophirboy - many thanks. You hit the nail on the head. The Gold Monster is a very High Gain detector and taming it via appropriate sensitivity settings is critical. With the GM1000 more so than other detectors lower sensitivity is often better.

Nice nugget!

Hi ophirboy, Apart from testing my Impact and ascertaining it is stable on our very high mineralisation, I have not found a speck of gold even though we have camped out in a tent in freezing nights for 10 days at a time. Yesterday we detected at Kitty,s Lead just South of Ballarat near where we live ,one of the richest deposits of large nuggets found in Australia.Surprisingly the ground had only low mineralisation with completely white quartz and few hot rocks.I am finding small non ferrous targets up to 4 inches deep varying from 0.1 to 2 grams.I always now keep the gain at 70 which is the default setting in the general mode and have never had to lower it to compensate for hotter ground.I think the Impact needs a lager coil for gold prospecting in Australia; the Black Dog XXL which is 13x11 inches and very light would be my favorite choice but it is unavailable here.We were thinking of going over to the West next winter but do not know if it is worth the long drive to get there and if there is enough free Crown land to detect in without running into leases everywhere.Perhaps you can give me the benefit of your recent experience.

Hi Mike 

The main thing about detecting is that no one has struck it rich with there detector in the cupboard . I'll read you a quote from a newspaper  correspondent at bendigo in 1852 " The new chum arrives believing that nuggets can be dug up as easy as potatoes in a farm paddock but soon discover that they will blister there hands and knock there shins on many a boulder before they see even the specks" If this sounds familiar your in good company . Detecting is about persistence and luck . You sound like your going to areas that are likely prospects however I purchased my first detector in 1976, it was a whites coinmaster 5000 D and I thought it was the ants pants it took me 2 years to find my first nugget but I just loved being out in the bush meeting and talking to other diggers. The Aussie diggings have been hammered for over forty years with all manner of detectors . And the PI detectors go very deep compared to vlf, so try and concentrate your efforts where the diggings where shallow or where the distance to the washing area was far away . Lots of dirt fell off wheelbarrows on the way to puddling machines or creeks. Or search out bedrock areas exposed on terrace or bench deposits as the yanks call them . These areas are obvious by the stacks of rocks with pathways between where the diggers washed the soil down to bedrock and needed to stack washed stone from the sluice boxes. If your finding small lead pieces then  your in the lottery with a chance , but as I have said before , ferrous junk can be identified by its irregular or wide signal . Rusting iron slowly leaches  into surrounding soil giving a small item a much bigger signal " halo effect" and a nail will even give a double signal because of its dual polarity like a compass needle. On the other hand non ferrous items with little corrosion give clean clear signals . These include brass bullet shells , eyelets, lead shotgun pellets , bullets and gold . I find detecting more enjoyable when you enjoy your surroundings and accept the junk as education that is slowly giving you the experience to find a nugget when your lucky enough to walk over one . I wish you well with the Nokta Impact and remember to share your knowledge with others when you become an expert.

Happy times on the diggings

So true, nothing has changed in 160 +years, even though we get about in 4 wheels and have these new fangled electronic thingos that look into the ground.

      OK, I would never have considered the Gold Monster as a coin detector. Micro jewelry maybe, but coin detecting? Well, in the U.K. most detecting is "dig all non-ferrous" and there is a need for sensitivity to small items because Celtic gold and cut silver coins are small targets. Still, I was quite surprised to see this posted on the Minelab Facebook page. Food for thought for owners of the GM1000.

      Hi All,
      This is my first post  :)
      I wanted to share my experience as a novice.
      My daughter and I were watching a you tube Video on gold detecting and we decided that it would be a fun thing to do together. So I went and spoke to a dealer and he suggested the GM1000.
      There was only the one review at the time that was very positive. 
       
      Four/ five months later and I have been out six times with my new GM1000 to Various locations within the golden triangle , All I had to show from it was a crap load of junk and a heap lead shots.
      I started seeing more reviews pop up so naturally I was  reading/watching the reviews on the GM. ( a lot weren’t good)
      I started to doubt myself and my machine.
      So I decided I need to go out with someone to tell me what I am doing wrong and to see if I had wasted my money.
      Via Facebook I discovered someone and went out with him for the day.
      He restored my faith in it and I learnt to trust the detector.
      The other thing I learnt was how to run it in manual successfully.
      After the training I went out again and it finally happened . I found the yellow stuff , Not just one bit either.
      Now I can’t retire on the two little bits (0ne .4g and the other .2g)
      However God it feels bloody good !
      Now I do plan on getting a PI detector at a later stage when funding permits however in the mean time I can now know that the GM can do what it was sold to me as.
      Good luck everyone!
      Rob

      How the GOLD MONSTER 1000 complements your go-to Premium Gold Detector By John Wilson
      “It dawned on me very early on in my gold detecting days that relying on one detector was not going to give me the best chance to recover the majority of gold on offer from all the goldfields that I frequent.  Using one detector was just not going to get the job done.  I would say that most of us who are more serious in our quest to find gold will know this and will very likely have multiple detectors for multiple uses.
      The more serious of us gold prospectors will rely on at least one of the premium Minelab Pulse Induction detectors, such as the SDC 2300, GPX-4500 or the GPX 5000, while a number of us will have the Minelab flagship GPZ 7000.  However, I strongly suggest you also consider a single high frequency VLF to maximise your gold recovery as relying on just one of the ‘big boys’ alone may mean you are missing out on plenty of gold.  Let me explain…..”

      Isn't there supposed to be an owners manual that comes with this detector besides that little "Getting Started Guide"?------How long does that rechargeable battery pack run on the GM1000 with a full charge & under "normal" hunting conditions?------How long does it take the battery pack to charge (AC plug in charger) when the battery is flat?-------Didn't see any info in that starting guide in regard to this.------I wish they would have made the shafts longer! LOL (I'm kiddin)-------I'm about 5'9" and I got plenty hanging off the back when adjusted for me.------So far, what little I have tested it, I'm really liking the detector although I haven't even had it on a hunt yet.-----If you've got any advice for me on this detector--I'm all ears!-------I've been reading up on what I can find on it.--------Thanks----------Del

      My last outing everything seemed to be fighting me - weather, equipment, and deep grass. Only managed a few dinks, 14.7 grains or 0.96 gram.
      All found with the Gold Monster 1000 and 10" coil except the smallest, flattest one. I decided to give the 5" coil another go. I rarely use it and with the reports on coil sensitivity issues I wanted to revisit it again to see if I am imagining things.
      Scrubbing the ground the coil was quiet at manual sensitivity 5 and the rocks started bleeding through at 6. This was not touch sensitivity - just that having the coil on the rocks would start giving a little mineral response from them at 6. My 5" coil does not exhibit any signs of actual knock sensitivity until I run it up to manual sensitivity 9 or 10. Even then it is no worse than I experience with my Gold Racer, for instance, when cranked all the way up. I have no way to know but I suspect at least some of what is being reported as touch sensitivity is the detector popping on mineralized rocks, which can happen at fairly low sensitivity levels with the 5" coil. If a coil is fine in low mineral ground and then exhibits "touch sensitivity" in more mineralized ground this is probably the case, as true knock sensitivity should exhibit no matter what the ground mineralization is. Genuine touch sensitivity is triggered even by grass or sticks which are not detectable.
      Anyway, the little flat nugget, third from right, was detected with 5" coil at sensitivity setting of 5. One nice thing is that the little coil is easier to run in deep grass than the 10" coil and that's where this little guy was found.

      I am NOT saying that nobody is having issues with the Gold Monster touch sensitivity. My unit is like a just prior to actual production model however and I am just not seeing it. That being the case my final comment on the issue is if it is happening to you, it sure is not happening to everybody and so there should be a fix simply by replacing the coils or detector or both. However, if it is a case of running hot and eliciting responses from the ground or rocks by doing so, it will never get sorted out.
      I do sympathize with those having problems and hope it gets fixed via your dealer or Minelab or both.
      One last note. I was trying both my Gold Bug 2 with 6" coil and Gold Monster with 5" coil on some quartz specimens I have from Alaska last night. They were originally found with a Gold Bug 2 and 6" coil. My method at the time was to visually find quartz specimens and then manually rotate them over the coil. This is because some of the gold in them is so tiny that the thickness of the rock blocks the signal  and so the rocks often need to be rotated just right to get a faint little gold hit. This is complicated by the need to keep my hand away from the coil since these hot detectors will pick up a person's hand because we are faintly conductive (blood saline and sweat salts). Anyway, the GB2 with 6" coil and GM1000 with 5" coil are really a match for detecting tiny gold in samples like this. The main difference is the Gold Bug 2 signal tends to fade away in a more linear fashion, whereas the Gold Monster 1000 tends to remain louder and then drop off very quickly.
