      Thought I'd do we show and tell these are from summer 2018 mainly bedrock hunting in upper creek heads .. using my gpx4500 and goldmonster 1000 all the fines in the left container were from the monster apart from a couple that were gpx or nox800   the two in the centre are 1.7 and 1.6 grams  still yet to break the 2 gram yet hopfuly this year .. I'll be pulling alot of you tube videos up if you want to follow my channel its nugget hunter new zealand ...
      I have a modded gpx4500 but I also modded the shaft to a 3 piece gold big 2 shaft it makes it very portable and easy to carry into hills

      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.

      KiwiJW was keen to go for a prospecting trip yesterday which I was excited about, last time we went out I found a 0.62-gram piece which is certainly one of my bigger ones.  We tend to have a lot smaller gold than the Aussie’s which makes hunting for gold quite the challenge when the average size found is probably within the 0.0X grams range.
      I couldn’t imagine hunting for gold when the average size piece is in the 0.5+ gram range or larger, I often get those big booming signals and as I get tired later in the day or on a hot day when I can’t be bothered just walk past them as they’ve been almost always 22 shells, but this day was different, even though I’d forgotten my lucky hat.
      We first went to an entirely new location for me which was a nice lake with old workings at it, I first had some trouble getting a ground balance with my GPX 4500 here, it took me quite a while to work out what to do, I was considering just putting it down and using my GM1000 but seeing I only had the 5” coil with me it didn’t seem optimal in such a big area.  In the end I just changed out of sensitive extra which I’ve stuck in since I got my GPX and went into normal, I haven’t needed to do this before but there was no way I was going to get a ground balance in this soil, it was near white soil with lots of nice gravels and quartz in it and looked very promising.   It’s lucky I had my little GPX timings chart with me that Steve had made up, it helped a lot in this situation.
      Steve's awesome GPX timing Charts
      There were lots of dig holes around from somebody in the area and the person who did them was annoying as a lot of them already had a signal in them which I re-dug only to find a bit of junk so I suspect the person was throwing the junk back into their holes. 
      JW was off in the distance detecting the bedrock which goes down into the lake, this is normally covered in water but on this day due to lack of rain I guess the water level was low exposing this bedrock.
      No luck was had at this location so we decided it was time for a fuel up at KFC before heading to a spot I call old faithful. JW shouted lunch and we had our usual feast, it’s a tasty treat, then we were all charged up and ready to go.  Old faithful is one of the first places I’d been to and we regularly end up here but it’s usually productive for us, JW does particularly well here and it was home to my old gold miners silver ring I found some time ago.  I switched back to sensitive extra timings here.
      Once at old faithful we did something different and detected right at the entrance, an area we have walked/rode on the E-bike’s past so many times but I’d never detected before.  We split off in directions and starting going for it.   JW was quick to find a bit to keep me motivated and it was insanely small, I can’t believe he can find bits this small with his GPZ but he does, and he does regularly, it’s no fluke.  I will leave the story on his bits to him as it’s pretty amazing. 
      I said to him, "oh that bit’s so small, there is no way I’d be able to get that with this detector" (GPX) so he waved it over my coil and what do you know, a signal, waved it deeper, a signal again, waved it at the depth he found it with the GPZ, and again an obvious signal! What is going on I was wondering, then I realised exactly what it is, I’d modified my settings and threshold due to the wonderful post Northeast did about thresholds on the GPX.
      He explained to me how to adjust my threshold, the thread also talked about volume levels which I also took note of and adjusted.  I was incorrectly running my threshold very high, and also had my GPX volume level very high and then going into my booster and the cranked up high again.  I gave JW my gold bottle to store his bit in as he’d forgotten his as he was likely to need it more than me.

      The grass growth was pretty insane, it's normally a dry desolate place, this year has been different.

      Fortunately this time the grass was easier to push over than last time so we were able to swing crushing the grass down
       
      What I was doing now is turning my threshold right down so it was silent, then I turned up my threshold so it was just audible and stable and left it there.  As for my volume I had the volume turned down very low on the GPX itself, and used the Steelphase SP01 enhancer to control my volume, I had it turned up to a comfortable loudness on that which gave me nice clear crisp audio, I had it in my preferred setting of Filter 2 using its pseudo stereo mode wired to 2 x GME SPK08 speakers wired in stereo.
      This location is known for it’s pellets and using a HF VLF like my GM1000 is just a nightmare here as you will spend your time digging pellets, 20 or more pellets is not usual but this is where the magic happened, my GPX was now doing as well on pellets as my GM1000, it was detecting pellets everywhere, even quite well buried ones, this new volume/threshold settings combination was opening up a new world of small targets I was missing.  I normally got six or so pellets a day with the GPX here, now I was finding them constantly.  It felt like these new GPX settings combined with the Steelphase SP01 enhancer and the Nugget Finder 14x9 EVO coil had just majorly enhanced the sensitivity of my GPX to small gold.  Thanks Northeast!!  I didn’t mind at all spending my day digging pellets as I was hoping it meant I’d find a small bit of gold that this spot is known for and JW had already just found, a real confidence booster for me.
      Shortly after something else unusual happened, a guy walked up and surprised me out of nowhere.  He was carrying a Makro Gold Kruzer he’d bought three days earlier and was a newbie at detecting but had done a lot of sluicing in the past.  He was keen for any tips I could give him so I gave him a few good tips on where to look but warned him that thing is going to eat pellets all day long, he walked off all excited about the prospect of finding gold as I told him JW over there has found a piece already and we’ve only been here 30 minutes or so.  It is so rare we stumble across another detectorist, we’re more likely to find a gram+ piece of gold than see another detectorist 😊
      I kept wandering around digging up pellets and small shards of metal excited knowing I’m really gelling with my detector on this day hoping a little bit of colour was on its way and then I stumbled into an area I will now call Mr Pocket 😊
      I had a big loud signal, I assumed it was going to be a 22 shell as I’d just dug a few of them in the same little area of about 4m x 4m but this time it was different, it was gold! I walked over to JW and said I’m going to need to share the bottle 😊 he was excited for me and I showed him my bit which I described as almost needing a wheelbarrow to get it over to him and we dropped it into the bottle and back I went to my spot.  It was the most unlikely of spot, no bedrock, no signs of any gold workings, just a grassy area near the creek side within about a meter or so of the dirt road.

       

      0.294 grams, not too bad, It looks bigger than it weighs for some reason, it's a lumpy one.
      This was quite a big piece for this location and seeing it was such a loud booming signal I kept digging booming signals in this little area and out popped another big one! I took it over to John to put in the bottle and said I’m onto something down here, and so Mr Pocket was born.  He now passed me the jar and said looks like you’ll be needing to hold onto this 😊

      It was almost down the depth of my scoop but was a loud booming signal.


      My first ever nugget over a gram! A rare find.
      I went back to my spot and the next thing to pop up was another bit of gold, this time not so big and more in line with our usual gold sizes around here but still, small for me with my GPX and down about 3 inches.  Pretty impressive and thanks to my new settings.

       

      This little guy wasn't particularly deep, 2 to 3 inches I'd guess.  But it sure is tiny for the GPX and it was such a nice stand out signal.

      I now felt I’d gone over this little 4m x 4m patch to my ability level so I called JW over to see if he could get any more out of it with his Zed and GB2.  I didn’t have a HF VLF with me so I was hoping he’d end up finding some gold the GPX missed with his two high powered weapons.  I showed him my spot and took off looking for a new spot.  Shortly after “new guy” walked up again, he’d been detecting about 30 minutes’ walk further along the roadside with his Gold Kruzer and had only found what looked to be 4 old rusty nails and a 22 shell.  I thought something is wrong here, a 61khz detector and no shotgun pellets in a place riddled with them.   I scattered a few pellets Id found on the exposed bedrock and asked him to wave over them, nothing at all even touching them.  I dropped my gold bottle on the ground and asked him to wave it over it, nothing, absolutely nothing unless he virtually touched the jar and then it did a threshold change.  Something isn’t right here. 
      I’d never seen a Kruzer before but helped him out with his settings on it and then got him to re-test over the bottle, this bottle had a piece over a gram it in, this thing should be screaming on it, and now it was working and picking up the gold at some depth.  His gain, discrimination and mode were now adjusted.  I still don’t know if it has the right settings but I told him he should be reading the manual.  It was now picking up pellets too but not to a level I’d consider good.  He said it was a choice between the Kruzer and GM1000 but he picked the Kruzer.   He was disappointed he wasted the afternoon with the wrong settings so even If he passed a 1 gram bit of gold he would of missed it ☹ This is where the simplicity of the Gold Monster shines, if he had of bought that, he would have been fine right off the start line.  He was appreciative of the help and we parted ways.   This made me think back to how lucky I was I had KiwiJW and this forum to help me out with my prospecting or I'd be in the position of this poor guy trying to work it all out alone.
      I went down to check how well JW did in Mr Pocket but it seems I’d cleaned it out, he got no more gold, reassuring in a way but also disappointing as I was hoping JW would get some out of it.
      I will leave it to JW to tell his side of the day, all I will say is him and his ability to operate his GPZ is a shock to me.  Here is a majority of the junk from the day, I'd lost a few pellets out of my pocket and I'd dumped a few on the ground for the new guy to test his detector on but I sure got a lot of small junk showing just how sensitive the GPX was.  I was regularly finding shards of metal even smaller than pellets.  The Minelab GPX 4500 with the 14x9 Nugget Finder EVO combined with the audio provided by the Steelphase SP01 Audio Enhancer is a deadly combination, I've never used a SDC2300 but it has to be getting up there to it's small metal finding ability because I know it's getting pretty close to that of my Gold Monster 1000.

      It was now time to head off, another great day prospecting and now my confidence is on a high.  I enjoyed going back to Johns house afterwards for a coffee and showing off my gold finds to Mrs JW,. Thanks for another good day John.

      The MInelab GPX 4800 was released at the same time as the GPX 5000. The Minelab 4800 was intended as the next release after the GPX 4500, but before it was released Minelab came up with a couple new refinements different enough to warrant yet another model, the GPX 5000. The 4800 therefore became a sort of "non-model" as most dealers and users focused on the GPX 5000 as the new top-of-the line detector. Most dealers do not stock the GPX 4800 and it may as well not exist for all the attention it gets.

      The fact though is that a GPX 4800 is basically a GPX 5000 less a couple timings. Details can be found in the GPX 4800 / GPX 5000 Brochure (excerpt of spec sheet at end of this post) but what it boils down to is the GPX 4800 lacks the Fine Gold and Salt Gold timings.

      Salt Gold is an improvement of the Salt Timing found on previous models that works better on salt flats and salt water beaches. Fine Gold is a bit misunderstood. Sensitive Extra is the best setting for pulling small gold out of most ground in the US. Fine Gold is intended for extremely mineralized ground. There are a lot of people who have decided Fine Gold is the magic setting but it really should not be used in milder ground where more powerful timings will do the job better.

      It really all boils down to the Fine Gold timing, and most people just went ahead and ponied up for the GPX 5000 for the extra $800.
