GPX 6000 Normal / Difficult Timing Tips For Trash And Hot Rocks

Recommended Posts


I like running the GPX6000 like a hotrod and trying to hear through the chatter, so I have been using Auto + with success patch hunting in a area that has very few hot rocks, just hit the difficult button when I encounter a hot rock and its usually gone, but will still get a great response on the small gold targets when switching to difficult, if in doubt I just switch from normal to difficult mode to see if it's a metal target or ground effect.  This matches up with what JP mentions on the small gold timings in the difficult settings. I also tried comparing the Auto to the Auto + but could only notice a very small difference. Would the Auto be comparable to one of the Manual setting, if so which number would closely match it?

Another thing I have been trying to do is determine the high/low tone responses on different objects in Normal vs. Difficult settings to help in trashy sites. Steve Herschbach has mentioned this in a topic linked below and got me started doing some testing. My goal is to use these setting to separate out my most common targets, square nails. Please read the article below to better understand this concept.

Gotta love that easy access ability to quickly switch between Normal and Difficult. People should just do it as a habit, and note what happens, and then what they dig up. Patterns may or may not develop that could be of great help. The results are directly related to the mineralization type and level however, so results in one area cannot be relied on to be the same in an area with different mineralization. But if you hunt areas that are relatively consistent, the results you get will also be consistent.

Frankly, I recommend digging everything when nugget hunting. However, that often goes out the window in an old hydraulic pit filled with square nails, or in a camp site built on top of the gold field, littered with old trash. If time is limited you have to cherry pick as best you can, and these methods will help with that.

I did this on my last hunt but all i got was lead.  Had a high/high on tiny lead and a low/low on a big slug.  Similar to what small and large gold “should” sound like.  I am waiting for a high/low or a low/high.

      So some of you know that my 6000 arrived defective right out of the box and that I sent it back to be replaced the morning after I got it. Well the new replacement arrived yesterday and the detector works as I assume it should. Well, at least it will sound off on a nugget, so I assume it is working properly. I have the 14" DD on to test that out. When I picked up the 11" to pull it out of it's plastic bag, I noticed something odd on the top of the coil. There was a crescent shaped crack in the coil. What in the world is going on with Minelab and their quality control.?!! People spend thousands upon thousands of dollars on their detectors, you would think they would be more strict and precise with their quality control procedures. I sent the 11" coil back to be replaced, this morning at 9 am. It is possible it could have happened in shipping, however the inner box and shipping box were in great condition. No smashed areas anywhere on the boxes. Anyone else  want to chime in about their particular Minelab detector defect. If Minelab is reading this, you have alot of people out there spending alot of money on your detectors because they are the best-Hands down, but it seems like since the sdc2300 came out the quality control is going down hill. I understand some defects can get by or crop up over a little bit of use, but this is not good.

      Yes I finally did get a chance to hunt for larger gold with the GPX-6000.
      This video has some quirks and I am sorry.  Shooting video is not my expertise as you can tell.  Error #1 and many of us do it.  Keep the phone Horizontal (left to right) to get full size viewing.  Error #2, be sure to have someone else shooting the video while holding camera Horizontal and not shaking as much.  Now for the bit of info that many of you may have missed in this video.  I won't reply with answer yet, but will give a hint "sound".
      So yes a get a little excited and yes I mumble and stumble for words.  Heck I sometimes freeze up and slowly look around to make sure nobody sees it or me.  I have heard other do that as well, why?  What would you do?

      I haven't seen very much conversation about the comparison between these two detectors now that the GPX 6000 is creeping into the SDC 2300's territory.  So far, the GPX gets both smaller and deeper gold.  Has anyone other observations?

      I've been reading about DD and mono coils for the GPX. I'm confused
    • By TnRebel
      I'm checking both out. Need some input by others.
