Report On Noisy, Salty Northern Nevada Ground, The GPZ And The SDC


Recommended Posts


Great report, Chris. Certainly shows why having more than one "arrow" in the quiver can be advantageous. Owning both of those machines I think would cover most prospecting situations. The addition of a good VLF for trashy areas would round out them out.

Did you notice much depth loss hunting in the salt mode on the SDC? Not that it would make much of a difference in that if the machine isn't stable you won't be effective at any depth. Thanks again!

Reading this post and other posts in the 4Ms archives, it seems you folks have ground just the same as we have here in OZ. Most of the ground I prospect in NQ OZ is only slightly noisy. If wet even less noisy and more depth penetration. Certainly not like your salt areas, nor like some areas of WA or in particular some patches around Wedderburn in Victoria OZ.

Got me thinking and must ask you fellows that have experienced both US and OZ fields, is there really any difference, is it just a myth downunder that our ground is the worst to detect in?

No Myth. Topographically places in northern Nevada look somewhat like WA, but geologically, its night and day different. We have some places in the Western US that are bad, some as bad as Australia, but overall, you are way worse. There are a few mild places in WA, and there are a few bad places in the US. We just have a lot less iron in the ground where most of our gold deposits are. Salt however, is totally different to ground balance as compared iron rich, magnetically reactive soils.

Yeah I did some detecting in the salt lakes of WA back a bit, certainly difficult. We are probably fortunate in QLD OZ, we do have some "hot" areas, but overall tis quiet, well where I`ve been. But I get you the iron richness is what makes WA  gold deposits different to most of yours.

Hi Chris, Thank you very much for the report and all the help and information you so freely give all of us. I'm really appreciative for the info and it will be a big help for me next month. thanks

 

with the GPZ, when encountering difficult salty ground, i imagine it is difficult to say exactly where you will encounter this problem other than by how the metal detector reacts. Or, do you tend to find the difficult salt ground to be in more low lying areas or pockets? Is there any relationship to heavy salt concentrations in higher areas that might indicate ancient low ground that may also have collected other heavy metals and by this could the GPZ's extreme sensitivity to salt be anyway advantageous?

Thanks  Chris for taking the time to do an excellent write up.

 

 That would have taken me all a day to write and I would have a blister on my finger.

Hey, I found some of that window screen wire with my 2300 in N Nevada too.   Must have been after Steve cleaned out the patch.  :ph34r:   Thanks for nice write up Chris.

I've found that window screen in a bunch of places. For some reason the desert old timers liked it - it was cheaper than a real window. One window screen, once rusted can break up and the wind will contaminate dozens of acres with little wires a quarter to a half inch long.

      The weather may have turned for the better in Northern Nevada.  It was time to get out and check how my GPZ 7000, would handle the moisture/salt from the Winter Storms.  I pulled into the Burn Barrel to camp, but it was like pulling into a KOA.  I unloaded my trusty RZR and hit the trail to find a nugget.  I ran into several folks out trying their luck, all had smiles on their faces and enjoying our outdoor hobby.  I was told that Gerry was having his training at the Burn Barrel which explained the crowd of RV’s.  I did get time for a short visit with Gerry and Lunk, before heading out.  The soil, is a little noisy with High Yield/Normal.  Using Difficult settled it down perfectly, but not my preferred setting for dink nuggets.  Anyways, I hunted in Normal and ground balanced often to give my ears a rest from the noisy ground.  I didn’t find any dink nuggets which are the Bread & Butter to any poke, but did find a couple of Steak & Lobster nuggets before loading up and heading home from the short Dirt Recon Trip.  There’s gold out there, you just need to get your coil over it, I need some Bread & Butter Nuggets to complete my meal.  Talking about meals, my Dog Marley refused to eat his normal dog grub on this trip, and only wanted what I brought “Fried Chicken”.  Until the next Hunt!

      I am not affiliated with this company nor am I an investor.  I do like a map they have put together.  It shows gold 'finds' all over norther Nevada with the center in Winnemucca.  They want investors and I liked reading some of the discovery info.  What do you think?
      I took a 'day trip' one Sunday north of Winnemucca leaving from Rye Patch.  It is a long distance up there.  Getting back I drove on the longest dirt road I've ever been on.  I know they are much longer in Australia but this road was a 'short cut' with 80 miles of nothing.  I should not have done it alone.  It wasn't in the summer but I still wouldn't do it again.

      Just the other day, I reached my goal of digging 100 Arizona gold nuggets with the GPZ 7000 this winter. Nothing of much size - the largest weighing in at only 5 grams - but even the tiniest bits are a thrill to find. As usual, I was targeting well known and flogged placer areas, working in and around the old dry-blow diggings. All up, 1.78 ounces troy. It will be interesting to see how much the GPX 6000 increases the number of nuggets found in this size range next season...only time will tell.
      Good luck out there!

      As far as a carry case, Beatup came up with a great idea for the 7000.  It's a double snowboard bag, 158cm fits the collapsed 7000 perfect.    Not a hard case mind you, but it's padded with waterproof luggage type exterior and heavy duty zippers.  It offers some protection bouncing around in my RZR, I bungee it to my overhead rack so there is still room for all the other gear in the rear compartment.  I'll try and find the website if anyone is interested.

      Hey All.  I have been researching this last month or so throughout Detector Prospector, Minelab's Knowledge Base and TreasureTalks so that I can take my skills with the GPZ to the next level and I think in order to do that it involves these 4 settings:  Threshold, Sensitivity, Volume and Volume Limit.  A lot of forum members talk about these comparing and contrasting, but none really give you a "How to."  How do you go about adjusting these to reach perfection, to reach that perfect ZVT zen.
      Conclusions that I have read are that: it just depends on what you want to hear, or how you hear what is coming out of the detector.  OK, but I think it is more to it than that, and if you don't understand what these controls do how can you really achieve the best results.  
      Keeping these setting the same.  Noise Canceled.  Gold Mode: High Yield.  Ground Type: Normal.  Ground Balanced with Semi Auto.  No filters - Audio nor Ground Smoothing.  Lets talk about how we start.
      Here is what I have researched and summed up describing these controls.  These are my "interpretations" based on everything I have read and I think I really have a grasp on it now.  This information and dissemination of it came from everyone here, and I mean everyone!  Huge Thank You!
      Sensitivity:  aka Gain.  Control of the INPUT "strength" of a "sound wave."  You don't actually control how "sensitive" the coil is.  ZVT is ZVT, that is the tech we are using  In order to understand these controls I think of it like a "sound wave".  What you control is the "sound wave" coming into the machine.  Too much gain and you over modulate the sound wave, cause distortion, and increase the "noise" level.  Too little gain and your "sound wave" is decreased (like making it a flatter line) maybe allowing large "sounds" to come through but in return lowering the "noise" level and small "sounds."  In Sensitivity is where you want to produce the "perfect sound wave" coming into the machine.  You want that sound wave to just barely reach below a distortion level to get the best "sound or tone"  
      Threshold:  This is how much of the "noise" level you want to hear.  It kind of acts like a bottom or "noise" filter.  Increase threshold (lower number on GPZ) and you filter out more of the "noise" level as well as small "sounds."  The opposite is to lower threshold (increase number on the GPZ) to filter out less of the "noise" level and hear smaller "sounds."
       
      These two setting should play off of each other so that you can achieve the "biggest window" for the ZVT "sound wave" to operate in with the least amount of "noise".  Some people use a 20 sensitivity and a 7 threshold.  Is that the biggest window they could achieve?  Some do a 15 sensitivity and a 27 threshold.  Is that the biggest window they could achieve?  How come you could not do a 1 sensitivity and a 53 threshold?  Nobody has ever commented on that.  Boost it?  Probably not a good idea.  I don't know, never tried.  Food for thought, but I hope you get what I am saying about that.
      In my eyes these two controls are where you should start.  Achieve the biggest "window" that ZVT can work with.  If you minimize the window you are not taking advantage of the full technology.  In turn you are probably not finding the smallest pieces you could achieve or  the greatest depth on targets.  Don't limit ZVT, maximize it to its full potential.  Open the window as far as you can for the ground/mineralization you are in.
       
      Now on to Volume and Volume Limit
      This is where I do not have the best grasp on these controls, even after all the research I am not sure if I am describing these correct.  So many people play off of these and have different explanations.  This is what I "think" they mean.
      Volume: aka Audio Boost.  Control of the OUTPUT "loudness" of the Threshold and Sensitivity window that you just created.  We are told that this acts like an audio boost and that increasing this by one is like increasing Sensitivity by 2, etc.  I don't think that is a good way to describe it, at least for me.  What I think Volume is doing is increasing the loudness of the "window."  Than includes the "sound wave" as well as the "noise" associated with it.  If you can not hear the targets you want after adjusting your "window" above, then you need to boost the audio.  Doing this though will increase what you hear in "noise" and  I "think" this is why some describe this as equivalent to increasing Sensitivity but it is not.  The "window" has already been set with your Threshold and Sensitivity, what volume does is change the OUTPUT "loudness" and there by multiplies how big the window is ("sound wave" and "noise").  This allows you to hear hear more, but more of EVERYTHING, in affect increasing overall loudness.  This is why it should be used "conservatively."  Start at 1 and work up until it is where you "like" hearing it.  This is the part that should be subjective to each individual and their hearing.
      Volume Limit:  The Big Mystery.  What does this do?  How does it help me?  Some say that this is actually volume.  Some say this is what you should adjust to hear targets better.  Some say it is just there to not blow your ear drums off if your volume is set to high.  My questions are:  Does this affect the "OUPUT" signal or the "INPUT" signal or both?  Why would I want a Volume Limit?  My thoughts on this......  I think that Volume Limit sets the MAXIMUM Volume (Audio Boost) "level" that can be used.  I don't THINK it limits the Sensitivity.  So this is an OUTPUT control.  Therefore if you set the Volume Limit high you would get a higher (louder) incremental step with each number in Volume (Audio Boost).  If you use a lower Volume Limit, you would have lower (less louder) incremental steps in Volume (Audio Boost).  So if you want more precise control of your Volume (Audio Boost) you would set a lower Volume Limit.  The trade off is maximum loudness.  If you need to hear things louder you are going to have to raise your Volume Limit and then adjust your Volume (Audio Boost) accordingly.  My thoughts are that people think this actually raises the volume but in the end if you keep Volume (Audio Boost) at 8 and increase Volume Limit, it will get louder per se because you just raised the the maximum loudness level there by increasing the loudness steps for each Volume (Audio Boost) number.  Make sense?  It does to me, I hope I am right otherwise I am gonna have to relearn this all over again 😉
       
      Well now I need feedback from you all.  Am I out in left field on all of this?  Am I spot on?  Or do I just need some minor tweaks? 🤣 
      AND if you have the desire to help some, could as many folks as possible make a video of them adjusting these settings to achieve a perfect balance?  These are the videos that are missing on YouTube, etc.  We see tons of people digging up gold but not many at all on "How" they use and set up their machine.  This would be huge to see.  You don't have to make a fancy video, maybe just have someone with their phone over your shoulder while you go through it.  This would be a huge boon for a lot of people, including myself.  Especially us that have to stay in all winter and have to wait to test their own theories. 🤣  So any help in that regard please post!  OR if you already found some vids, please share.  I have tried every search I could to no avail.
      Anyways many members on here have said it before.  You need to learn your machine.  Its only one aspect of being an expert detectorist.  I know I am not there yet cause it sure looks like I am still trying to learn my machine.  The rest for me seemed to have come easier, researching locations, reading locations, putting the coil over the gold, etc.  Now I NEED to revisit a bunch of locations where I got the easy gold by just using preprogramed settings that I learned when I just started.  I started detecting at the SDC level.  Turn on and go.  I never had a GPX so comparing to the old never helped me.  I am part of the new school of detectorists and I don't want to be ignorant by having less control.  I want to take control.  Its time to achieve ZVT zen and see what was left behind.  Its time to level up.
