Which Detector For Australia?

Recommended Posts

Hi Guys n Gals.

I’ve never ran a detector but very much looking forward to it. I live in the Nth East of Victoria Australia with access to what was some of the richest gold fields. I have no idea as to what the ground is like but it would be a fair guess that it would be at least reasonably mineralised.

I know i will be a beginner but i dont want to spend my limited budget on a beginners detector. I’m willing to do the hard yards with the likes of an intermediate detector. The areas that i would be concentrating on is Beechworth and the Buckland Valley etc, so the ground will have plenty of iron and the likes and mineralised. I will be working mostly around the mines on hillsides etc. 

I noticed a used Nokta Fors Core for sale so did a little research. Nice detector. VLF struggling in the mineralised ground or does the Nokta fair not too badly? A good used GP3000 is going to be twice the price and above my budget but i could work on that. Lack of descrimination would probably be an issue at these workings? Whites SPP? I’m finding it hard to get too much info on these but from what i have read they seem like a good detector.

Because of the likes of the trash and mineralised ground, i’m finding it difficult to choose between the VLF and a PI. I could start with the likes of the Nokta and purchase the likes of the GP or SPP further down the road.

Does the SPP come under another name or as an updated model?

Thanks all.

Al.

Hey Al

I can only speak from my personal experience within the Victorian Goldfields. We have some of the most mineralised ground in the world. The honest truth (IMHO) is that most, if not all, VLF machines will struggle. The likes of the Minelab Goldmonster, Fisher Gold Bug etc will get gold but you have to pick your ground. White pipe clay, mullock heaps and quartz piles are the usual targets for those machines. They certainly don't punch as deep as a PI machine and are harder to work in our soil. But they are cheaper.

As for PI machines - not all are created equal. Although the basic technology is the same, the way they handle mineralised ground, emi etc is very different. Basically you get what you pay for. For my way of thinking, for a beginner who wants an intermediate machine thats easy to use and a proven gold getter - a Minelab SDC2300 is the way to go. The Whites is an ok machine but I have yet to see one perform as well as the Minelab (down here anyway). I have only seen one in use down here and it has found gold but not much. The user was struggling to get the depths of the Minelab due to having to dumb it down to handle the mineralised ground.

Now I do admit that I am a Minelab fan so I'm probably a little biased but if I am always open to other machines if they prove themselves as capable as the Minelabs. In other countries where soils aren't quite as hot, I'm sure I'd certainly have more of a choice.

Disclaimer:: I am only speaking about how the machines work over here in AUS (especially down in Vic). So please all you guys based in the US, dont jump down my throat because another machine may work better over there. 😎😎

Hi Pat, thanks heaps mate.

well the Nokta sold.

Pat, how would the SDC (or any PI for that matter) fair with so much trash about? There would be a huge amount of iron/nails etc.

Is there was a VLF that would handle the mineralised ground better than what a PI would handle trash?

Thanks mate.

PS... Ocean Grove was my haunt as a child/young bloke during the summer months. Fond memories.

Also Pat, the SDC is out of my price range ATM. 

How would the GP3000 fair?

The areas that i would be concentrating on is Beechworth and the Buckland Valley etc, " 

Most of this area is either Mountains or  Rivers (Dredge Rivers). Dredged Tailing  would most likely be the target area but my look at the spot, showed most areas either covered with blackberries or private farms.

I have two ML3000 great machines but some of the latest higher frequency VLF have some good feed back in East Victorian for creek sniping  for specks and specimens. By the way the Golden Triangle is still the best bet and the ML GP's or better is the way to go.

Thanks Geof.

Yep, mountains and rivers. Oh there are plenty of areas that can be scouted thats for sure.

Wouldnt the higher freq VLF’s struggle with the high mineralised ground over the lower freq? Sorry if i have this arse about. The more i read, the more confused i get.

Maybe for the interim i should get something like the Monster 1000?

Cheers guys.

The White's Sierra Pulse Pro (SPP) was a special limited version detector.  It was initially labeled the "GMT Super Pulse" and exclusively(?) distributed by Associated Group of the United Arab Emirates to the African market.  When they didn't sell well, Jimmy Sierra was offered and subsequently sold them through limited White's dealerships in the western US (and directly through his website?).

The SPP is simply a standard White's TDI/SL (still on the market) with a couple controls removed:  the variable adjustment for pulse delay (nominally 10 microseconds to 25 microseconds on the SL, locked at 10 microseconds on the SPP) and without the conductivity switch found on the SL model.  All the TDI's have a simple type of discrimination -- low conductor vs high conductor -- and the switch on the SL allows you to choose either one or to hear both.  With the SPP you just hear both tones and let your brain discern between high and low.  (There is some noise reduction advantage choosing high/low as oppose to both.)  Oh, one other difference is the coils which came with each detector.  Coil choice of the TDI has never been a problem since besides White's selection, aftermarket coils (Miner John, Razorback, MInelab, Nugget Finder, Coiltek) abound.

PI machines dont discriminate. Therefore you dig every target. High trash areas can be a nightmare but also very rewarding if you have the patience.

VLF machines can discriminate the iron out but its a tradeoff for depth in mineralised ground. 

Basically ALL VLF machines will struggle with mineralised ground. The higher frequency machines are great for smaller gold but only if you pick your ground as I mentioned before and as geof_junk mentioned for sniping creeks etc. The guys using the Monster and Gold Bugs are doing well going over quartz piles, quartz reefs, tailings and old mullock heaps. They are finding the small gold the old timers missed.

Maybe this can help you decide?  If nothing else a vlf is much cheaper than a PI and to be really complete you should eventually have one of each????

      Hiyas...I recently dug a part of a pewter flatware.  I have never seen a makers mark or other identifying mark on flatware that I have dug before.  Putting it under my scope, and fooling around a lot with lighting directions, this is about the best it is going to get.  Any one have access to pewter manufacturer information?  I am stumped so far.
      The bottom is METAL, the top left looks like a B or S to me, and the right side I believe is NTA

      So I have a Tesoro Mojave that I love, it made me put the "all mighty" AT Pro down and never pick it up again. But ever since I got it I couldn't use it on the "Low" ground condition setting because it would false like crazy. I finally decided to have a serious look around and see if anyone had this problem and had fixed it and I couldn't find anything. I posted on treasurenet to see if anyone could help with at least some knowledge of the trim pots on the circuit board but i didn't get much help. Then I remembered about a website I saw a while ago, TreasureLinx, that had some diagrams of Tesoro mods on it. So I emailed Sven, the owner and asked if he could help out. He told me which trim pot controlled the ground balance and I fixed the problem, at least so far I think it's fixed. I'm going to copy and paste the posts I made to treasurenet and the email to Sven here...
       
      (POST 1)
      Hey all. I've searched around google but I can't really find any information about this. I bought a Mojave on eBay a year or two ago and I love it. I found my first and best gold ring with it and i even ditched my AT Pro in favor of it. The problem is it's always been pretty hot and falsed a lot in the low setting of the GB. In southern CT I had to run it on the high ground balance even though I'm pretty sure the ground there isn't that mineralized. I love in Costa Rica now and the few times I've taken it out it likes to false on the high GB setting and the low is basically unusable.
      I've tuned the ground balance on my compadre that ran hot when I got it too but from what I can see there's no GB potentiometer screw on the Mojave. Does anyone know of anything I can do tune it a bit so it doesn't run so hot?
      (EMAIL TO SVEN)
      Hi, my name is Josh. I have a Tesoro Mojave that runs hot in high ground phase mode and I was wondering if you knew if either of the trim pots on the board are for adjusting the ground balance? I'm trying to ask on treasurenet and on the Facebook Tesoro group but I'm pretty sure it was you who put a manual ground balance on your Mojave.
      I've adjusted my compadre because when I got it it would false on some basalt rocks and now it runs perfectly quiet. But the Mojave has been chattery since I got it. Here's a picture of the board, I don't think you need it but I marked the two trim pots and the two wires coming from the ground phase toggle. Thanks!
       
      (EMAIL BACK FROM SVEN)
      Hi, one towards the PCB center should be GB pot, the other will be disc bias- don't touch it.
      Tom has reworked his Mojave with full mods, contact him thru Findmall https://www.findmall.com/profile.php?56,1260
      Sven
       
      (EXPLANATION OF MY SOLUTION ON TNET)
      Ok I fixed this one too (I'm referring to the almost same problem I had with the Compadre that is documented on this forum also). I emailed Sven from treasurelinx, hoping he'd see the email and get back to me at some point in the next couple weeks...it was less than 12 hours before I had a reply. I asked him if he knew which trim pot, if any, controlled the ground balance. He informed me it was the one on the left, the innermost one that did. The one on the outside controls the discrimination and should not be touched. Here's what I did.
      I opened up the control box and exposed the board. I made sure the disc was set to the lowest position in iron (basically no disc), the sensitivity was on 4 and the ground condition was on low. I took the coil and pumped it at the ground and it falsed. I then turned the trimmer all the way CLOCKWISE until it wouldn't turn any more. I did this very very easily and lightly. If you attempt this remember, easily and lightly. I then pumped the coil to the ground to make sure it wasn't falseing still and it wasn't. Then I started turning it back COUNTER CLOCKWISE a tiny bit at a time until it started to false and then turned it slightly back CLOCKWISE to where it didn't false any more. Remember, the movements are slight when turning the trimmer. 
      I also noticed that when I touched the yellow wire coming from the ground condition toggle, it made the machine false also. Knowing why and being able to fix it is probably beyond my knowledge and comfort zone so I made sure that when I put it back together it was snug and didn't move. I'm guessing some of the falseing was for that wire and other falseing was from the ground balance being off.
      Again, this was the solution to my problem. It might not be the same for everyone but it worked for me. I hope this helps at least one person with the same problem since I couldn't find a solution for it myself, or even a good picture of the board
       
      Here are some pictures of the Mojave board for reference

      Who here has dug one, if so, what mode were you in and do you remember what the VDI was? Also, does anyone have one you could do an air test in park 1.  My buddy and I are hunting an area that is old enough to possibly have one lurking about. I understand my soil, the orientation, etc will affect VDI's, I just need a baseline to start with, thanks.

      Australian man finds 624g gold nugget worth $37,000 while walking dog
      13 May, 2019 7:56pm The father said he had been informed the nugget would likely be worth more than the A$35,000 estimate if it was sold whole. Photo / News Corp  
      An Australian family have literally struck gold after finding a valuable gold nugget during a Mother's Day outing.
      The family from Bendigo in Victoria, who asked to remain anonymous, were walking their dog — fittingly named Lucky — on the outskirts of town on Sunday morning when the daughter kicked something hard lying on the ground.
      At first, the father and his two daughters were unsure of what they had found — but it has since been confirmed by experts as a 624 gram gold nugget with an estimated value of at least $35,000 ($37,000).
      "I actually walked right past it but my daughter pretty much kicked it as she was walking. She then goes — dad, is this gold? I said, I think it might be," the father told the Bendigo Advertiser.
      The stunned family first took their find to an IGA supermarket to weigh it, with the rock coming in at 624 grams, or 20 ounces.  The father said he had been informed the nugget would likely be worth more than the A$35,000 estimate if it was sold whole, and that he did plan to sell it eventually.  He said the unexpected windfall had come at a crucial time.
      "We've come on some tough times so it's really good because we've been struggling financially. It couldn't be better timing really," he told the Bendigo Advertiser.  "Just having it at home, I've been like where do we store it? I haven't been sleeping very well and we think it's best just to sell it."  He said the "really random find" had inspired the family to return to the site and look for more gold lying beneath the surface.  "Usually when you find a nugget that big, there will be more gold around so hopefully that's the case," he told the publication.
      However, it's not the first time an Aussie has struck it rich.  Last September, a huge gold nugget worth at least A$110,000 was uncovered by a retired prospector in remote Western Australia.  That find weighed in at a hefty 3.23 kilograms and was dubbed "Duck's Foot" because of its unique shape.    And in 2017, Surfers Paradise gold digger Greg Cooke made headlines after finding several gold nuggets on a northern Gold Coast beach over several visits.
      In fact, Australia is famous for its treasure trove of gold nuggets, with eight of the world's 10 largest found in the country over the years.  The "Welcome Stranger" nugget, pictured below, weighing between 2380 and 2284 ounces, is the biggest ever found on the planet and was discovered at Moliagul, near Dunolly in Victoria, in 1869.

      Hello everyone, this is my first post. I've been collecting coins for almost 15 years, and years ago I started rock collecting thanks to my daughter who got me interested. If you put this two ingredients together... I would like to start with metal detecting focus in current and old coins. Going to parks, lakes, old houses, beaches, rivers, you name it... but like I said before, focus mainly in current and old coins to add to my collection!!!)

      I've been doing research for which machine to get and I know for newbies like myself this can be overwhelming and tentative (NOX 600/800) because there always going to exist a better machine for a little more money than what you are planning to spend an sometimes discussions in forums can confuse you even more. I'm a very dedicated person I do not mind spend time to get to know a MD 


      Which MT would you recommend me to get to find coins anywhere (not necessarily waterproof but I will need it for shallow water)
      under 500$?

      ... I live in Maryland just as a reference.
