Hello Friends 😁

Someone recommended me to start with a GPX 5000 for my Project. He said its not a big difference between a GPX 5000 and a GPZ 7000. So i have some questions, i hope you can help me.

Is it true that the GPZ can measure about 40 Percent deeper comparing to a GPX ? Is the GPZ really so much better that its worth to pay a higher price?

Which one of them would be easier to use for me, as a newbie? Is it smarter to start with a GPX or GPZ, what do you think? 

If i come in rainy wheather is it possible for the GPX to resist? Has he a IP64 code?

What about to buy a used one? I read that the older GPZs works sometimes better than the new ones, is this true? Is the newest software ( 31/7/17 NEW SOFTWARE UPDATE ) really always the optimized one?

Look here under the category FIND_BLOG, the same you can also find for the GPZ  http://www.minersden.com.au/minelab-gpx-5000-metal-detector-11-in-mono-coil-bonus-15-mono-coil  !  Are this just storys so that they sell the Detectors better or is this realistic? What do you think?

What is the different about the GPZ 14 coil is fully waterproof to 1 m (3 ft) and GPZ 19 Super-D Coil? Is one of them going more deep, or is it more sesitive?  What Coils do yu use with yur GPZ or GPX?

 

Thanks a lot for your answers.

Neither detector is waterproof. The coils are water resistant to a  meter or so.

You didn't say what type of gold you are after. Big nuggets? Little 1/2 gram and smaller nuggets? Very fine gold?

Invisible gold?

A Equinox 600 or 800  a Goldbug or Whites may be all you need.

The 5000 is an excellent detector with many coils available.

The 7000 is my favorite and is the most expensive.

Think it over...Read Steve's recommendations and get back to us.

The GPZ may outperform the GPX on certain gold types by a wide margin. It also can have issues with some ground types the GPX handles easily. For the majority of gold my personal opinion is they are in the same ballpark once you use the optional GPX coils to good effect. The GPX is the "safe" choice.

A used GPZ can be updated to the latest software. Beware used models - counterfeits are extremely common overseas.

One of my mates bought his second 7000 a few weeks ago. We did some testing against the 4500 using both the 11" and 14" coiltek elites coils. (not a lot of difference between a 4500 and a 5000 IMO)

We placed some test bits of gold in some mineralized ground and at another site with less mineralized ground. No matter what settings/timings I used I couldn't hear the small bits of gold that the 7000 could. We even tried cranking the 4500's gain to 15, stabilizer on 20 and audio set to boost. We also tried using sensitive extra and normal timings but it couldn't match the 7000 on the small gold.

On a larger bit of gold, I matched the 7000 but not using Enhance. Had to go to Normal timing and set the gain to 5. However, the 4500 was not really usable in the surrounding ground unless the gain was lowered to 1.

At Gain of 1, it still picked up the test bits but not as clear as Gain on 5 which i felt heard that bit as clear as the 7000. 

Obviously, testing like this is not the same as testing undug targets but unless one machine handles air tests better it seemed a reasonable way to compare machines.

From what I saw it made up my mind that its time to get rid of the 4500 and buy a7000.

Hey Jin, how small were the small nuggets?

Hi Nenad, 0.27 gram was the small one. I dug a thin trench about 2" deep gradually getting deeper to around 10" deep. We moved the gold deeper until we felt the zed would recognize it as a target if we were detecting the area.

I have gold specimens a GPX can’t detect, period. That the GPZ detects at several inches. What percent more is several inches over 0 inches?

I too have a piece of gold my GPX 4500 can't detect, it's .5 of a gram from memory and very lumpy looking like honeycomb.  No settings or coil I've got can make the GPX detect it even touching the coil.  I think I found it with the GM1000.  But by the sounds of it I'm glad we have mild soil here for the 4500 as I always run sensitive extra and am easily able to pick up a .27 of a gram piece with quite good depth.

Phrunt, my 4500 picked up the 0.27gram bit easily just nowhere as deep as the 7000 did. I think from memory i found this bit using the 18" Elite coil.

Hey Guys, I have another question:

How much would you pay maxium for this used GPZ 7000 from 2015 updated with the newest software, in very good condition?

      Hello All,
         Out here in Arizona, USA, it's been very hot and now humid as the Monsoons are right around the corner.  That being said, I have been poking around an old placer location loaded with iron rubbish in search for overlooked gold nuggets.  I have made it a point to start very early, right at day break and hunt until the heat runs me out (typically 4-5 hours).  I was using the Minelab GPZ 7000 and placering a wash bottom down to bedrock like the old-timers would.  I'm lucky every so often to get a nugget here and there wedged in the bedrock cracks/crevices that the old-timers missed or overlooked.  It's always a mystery to wonder what the old-timers really discovered in some of these really rich coarse gold placer areas.  

      I'm not sure of the rules about Youtube videos, but I have attached two of them for your viewing.  Hope some of you that are not able to get out right now can enjoy the adventure with me.

      More speculation.

      I go about Ferrite balancing a bit differently to what is shown or advised, this is my own preference and is to do with Saturation noise and Salt signals, especially with the X coils because they can Saturate quite badly. 
      Instead of the Octopus wobble I briskly (not too brisk) wave the coil over the ferrite from left to right under the blue sticker at the front of the GPZ 14 coil, this is with the Quick Trak button depressed of course. DO NOT scrub the coil on the Ferrite this is because there is always a bit of residual signal especially in Saturable ground, once the ferrite noise dissipates I release QT and pump the coil to one side (make sure you are in Semi-Auto GB mode), this then gives the GB accuracy as a DOD coil will always sound quiet from side to side even if the GB is out, once there is no noise up and down then come over the Ferrite again to check if there is signal and repeate the process using QT if there is. Pump the coil to one side again and check the Ferrite again. This whole process should take 20 seconds, eventually you will get no ground signal up and down (Ground Noise) and minimal signal over the Ferrite. 
      If the ground has BAD Saturation signal the Saturation signal will be magnified up through the centre of the Ferrite thereby preventing you from getting the coil close enough to actually balance the Ferrite out fully, in other words the detector will be trying to balance out the Saturation signal and not the X signal off the Ferrite.

      I also recommend users adopt the GB configured to their USER button approach and to go into Manual mode when checking deep targets or committing to dig, leaving the GPZ in Semi-Auto will allow the GB to drift either through exposure to the pick whilst digging or just general drift through the coil not moving, either way the GB will be out which is not obvious unless you pump the coil.

      A couple of months ago I put out a call for the parts list for the WM12 because my original WM12 was taking forever to charge.          At the same time I bought the replacement battery, I also bought some heavier charging cables because I have about half a dozen devices that all use the same cable. I bought cables that were listed as suitable for external hard drives and they were about 6 bucks each. Because I kept changing cables on different devices I don`t even know now what cables came with the WM12.         Anyway, with the heavier charging cables my original WM12 now charges QUICKER than the newer WM12, so I don`t need to fit the battery.        Maybe, if your WM12 is getting sluggish charging, it may not be the battery, it may be the cable breaking down.   Just a thought.    Dave

      GPX 4500. Been detecting for a while in the hills in California (Sierras) where I got started in 1970 ish with my White 5000 D I purchased from Jimmy Sierra at his shop in San Rafael. We’re still in touch although he says he doesn’t get out anymore but loves to read about others adventures. 
      then moved to New Mexico. I decided recently I needed to try my hand with Minelab and purchased the GPX 4500. I’m finding it difficult to find reading material on settings or proper videos. I have a friend that suggested a setting for the area I prospect in. I got a mono Commander and a GP Series coil with it. Hopefully I’ll find good info on this site. 😎
      Cheers

      I’ve been hunting a good site using the Deus and Equinox which has nails and small iron mixed in with good targets, some good targets being deep, but near or in the iron. My question is, will a GPX with Iron Discrimination turned up and the smallest DD coil pull out the deeper, non-ferrous items amongst heavy iron? Has anyone had any experience with this? I think for shallow targets the Equinox or Deus works better for shallow targets in this “machine gun iron”, but would like to see what others may have insight on for using the GPX. I’m assuming the fast setting and special soil timing may need to be adjusted as well. Thank you in advance.
