Settings Help For Lode (free Or Float Also) Fine Gold With Gpx5000

Recommended Posts

Going back out to a place I've been to a lot but with a twist. Finally talked my buddy into flying me out with his helicopter. We went last week but only got on the ground for a few minutes before we had to leave because of weather. In 5mins I had a little nugget (pictured, soaked in muriatic acid). I mined in this area last year running a test for hard rock. On out days off we went out with the detectors, GPX5000, GPZ7000, SDC2300, and two gold bugs (not sure the models). The gold bugs crushed it and the SDC2300 next and then the 7000. The 5000 was last. Non of us really are proficient with any of these. I maybe have 50hrs on the 5000 over the past 4 years. A lot of the pieces are small and kinda wiry.

So im going back up with the 5000 and would like some help on recommended settings to start with. I have 3 coils. The two that came with it and a small 8" mono. What would you guys recommend? Thanks!

What an adventure!  I would try to look at some of Lunk's post about the 5000 in the past.  Here is a thread you could get a bit of info from:

I'm searching for more to help you.

I still have my 5000 but have only used it a couple of times in the last 3 years.  It still works when I work it.  I found my biggest pieces with it.  In some areas it is all you need on under worked patches.

There are many threads here that suggest specific settings for specific spots and you should look those up but you should also consider just staying near the default settings.  I'd also get to know that 8" coil as well as you can.  It is a pretty nifty coil and can find some big gold if it is around too.  It is great on the steep terrain you are showing.

There will be more people chiming in I'm sure.

I'll check those out and do a little more searching. Is the 8" coil good/better for small gold too? Thanks

Is there a reason you are using the 5000 instead of the other detectors? They are all better suited to crystalline, wiry, or lode type gold distributed in quartz than the 5000 is. Generally speaking anyways, depending on what sort of ground you are in though, but it sounds like they all worked well previously in that ground.

The smaller the coil the better for small gold on the 5000 though, yes. Mono coils are more sensitive than DD's, especially when it comes to the old style or stock coils.

If you are detecting the side of that hill pictured, and you have all the detectors mentioned, I'd be taking the Gold Bug 2 and the SDC.

The 5000 is all I have. The other guys who have the other detectors are not apart of this new area. My buddy with the helicopter is thinking about the minelab 1000 or maybe the fisher 19.

Okay looks like I will run the smaller coil. Thanks

 What Jason said.  Get yourself the smallest coil you can like the NFinder 8x6 coil. But the sdc will still walk circles around the 5000 on that "low conductive" type gold.

Also might be worth mentioning that Sensitive Extra and Sharp timings are generally more sensitive on the smaller, speci type gold than Fine Gold is. Fine Gold is, to me anyways, more of a timing to be used to mitigate hot ground. My experience with the 5000 is limited though, as I stuck with my 4500 since I didn't find much use for Fine Gold in my conditions.

Not knowing your ground type, and if I went in blind with your equipment, my game plan would be something like this:

1.) Start with Sens Extra/Sharp with the 8" mono, run the gain up high until the ground gets too loud, then kick it back a notch. Out in the middle of nowhere and with a small coil, you may be able to get rid of some Stabilization and gain a bit of sensitivity to small signals, that setting works opposite how it seems to work when you turn the knob, check your manual. Stabilzation masks a lot more tiny/crystalline type targets on the GPX series than most realize.

2.) If ground is causing too much problem, back off gain to 8 or 10 and then if problems persist, switch to the 11" mono instead and fiddle with gain as needed.

3.) If ground is still too bad, try Fine Gold with the 11" mono. If that quiets things down, try it with the 8" mono now. You should be able to run higher gains in Fine Gold on both coils. You will be losing some depth now in this setting though. The smaller coil will have better sensitivity to smaller gold, the larger coil will have slightly better depth.

4.) If ground is still too bad, a last resort is the 11" DD.

It may sound complicated, but that is the routine I would go through to determine how to run that setup in a new place if I were trying to squeeze every ounce of sensitivity to that type of gold out of the 5000. Alternatively, for simplicity you could just put the 8" on and run in Fine Gold at default settings and be fairly safe, but if you want to squeeze performance out I would try a routine like this.

As Wes says, an 8x6 would be great for that type of gold and terrain if you can get such a coil up there, and if you can buy a new generation smaller coil then getting one with spiral (flat) windings will add some sensitivity to that crystalline/tiny stuff too.

      Early wet Weather in Northern Nevada, sure messed up a few of my hunts!  But, this last Hunt was called Rain or Shine!  Be there or miss out with the original hunting party.  We had half the amount of coils on the ground during this hunt and managed to find a few sweet spots of dinks to add to our pokes.  Rain on us with snow in the ground 200’ above us all 4-Days!  6000, Retune Button got a workout.  I kept the 11” Mono on.  Tried the DD for a few hours with no luck, don’t know if the ground and line I took was bad, but the guys behind me where finding nuggets…so back to the 11”.  My truck is out in the drive way in the wet Weather still loaded up with me gear!  Getting wet again to unload it, I can’t wait 🤨
      Until the next Hunt!

      Is there or has there been any comparison testing done in the field on depth with the 6000 vs the 7000 using the NF 12" Z-search coil.
      Thanks . . .

      I had something strange happen, today. I had my GPX 6000 battery fully charged and fresh off the charger.  It had completed its charge cycle and then trickle charged overnight.  I popped it in the detector and started detecting. Within five minutes the battery meter dropped from three bars to two bars.  If I turned off the detector and let it sit for a 5-10 minutes and then turned it back on, it would go back up to three bars for a short period of time before then going back to two bars. Has anyone else noticed this with theirs?

      as I already put in another post, I just bought a second-hand gpx 5000.  It comes with the comander 11 DD and 11Mono coils.  I would like if it is possible for a colleague to recommend a coil to complement the ones it brings.  Its use would be to search for coins.  I've been looking at the detech 15 inch DD ultra sensing.  If anyone has used it, what can you tell me about it?

      Hey all, still have a gpx 4000 I bought from AK M&D. Guess it's time for an upgrade. My Question is does the 4500 have enough improvements to justify the upgrade
    • By The_Stalker
      After reading all items available I am confused.  It's probably just me so I apologize if this is a dumb question.  In soil that has low mineralization which coil will go deeper and is more suitable, a DD coil or a mono coil of equal size?  Or in low mineralization does it not matter if you use a DD or a mono coil?
