Jonathan Porter On Mastering The Minelab Gold Monster 1000!

12 posts in this topic

Here it is!

"Savvy operators will be able to work the GM 1000 in surprisingly noisy ground once they come to terms with the methods I’ve described above. It takes practice but the effort is well worth it because these two Auto functions in combination with Zero threshold really does allow this detector to work in ground a VLF has no business working in - areas that I would consider to be MPS and MPF territory. In the quieter soils, Auto+ lifts the sensitivity to levels that surprised me, behaving like a much higher frequency machine Although not a ‘deep-punching’ machine like an SDC 2300, the GM 1000 still ‘holds its own’ on the shallow surface gold crumbs missed by the more powerful Minelab detectors."

Steve, how do you think the GM1000 compares

to the Fisher gold bug 2?

I made fairly specific comparisons to the Gold Bug 2 in my previous posts on the subject. I do not have a GMT to compare to but performance should be comparable. Again I hope my previous posts would serve to enlighten people on the subject. It just as always will depend more on the ground conditions and operator than anything. This is a 45 kHz single frequency metal detector and no rules of physics have been broken. Anyone that is considering the various alternatives and unsure at this point what they want to do should just sit back and wait for more reports from more varied sources to roll in. It's not like I have the complete picture by any means. 

I did some marathon posting the last few days. The stage now belongs to JP and I am hoping to hear more from him while I take a short break for a couple days.

This answered it for me:

" if you are an old Pro running a 71 kHz Gold Bug 2 with 3" x 6" concentric coil in low mineral ground, such that you have the sensitivity at max and are running in the low mineral setting, then expecting the 45 kHz GM1000 to match or exceed it on the tiniest of tiny bits is expecting too much. Conversely, if you are running a 14 kHz machine with a 14" x 13" DD coil and expecting the GM1000 to beat it on larger deeper gold you are expecting too much. If you are expecting the GM1000 to come close to replacing a SDC, GPX, or GPZ, you are expecting WAY too much! "


The 1000 does appear to have its advantages... read the reviews.

It does help if people have questions that the questions are specific. When I am asked what I think of the 48 kHz GMT vs 45 kHz GM1000 my immediate thought is they are both metal detectors with similar features and performance. I can go find gold with either. I have a GM1000 so I don't necessarily need a GMT. If I had a GMT I would not necessarily need a GM1000.

Is the Gold Monster 1000 the new detector with new features that is so advanced it automatically obsoletes all detectors in its class? You no longer need look at or even think about any other VLF? I get the feeling that is what people would like to hear. Wouldn't it be nice if life were that easy! Sorry, no.

In my opinion it is nice to have a "big gun" like a GPZ or GPX as a primary unit. It can also be good in addition to have a mid frequency (13-20 kHz) detector to deal with trashy ground and/or a higher frequency (30-80 kHz) unit for tiny or specimen gold. For people who can't afford or do not detect enough to need the big gun the mid or high frequency detector can be the primary unit. Mid frequency detectors are better "all around" units and so better for those wanting a general purpose machine. Higher frequency detectors are generally dedicated prospecting models and so a better choice for those wanting a detector purely for prospecting.

Therefore in general for "prospecting only" a big gun or a high frequency unit can serve best either separately or together. Mid frequency offers more versatility (coins, relics, jewelry) for those who desire such things.

When having multiple detectors the key is they should all be as different as possible. If you already have a big gun a second machine should specifically do something it can't do well. Therefore the idea of getting a mid frequency or high frequency detector. In the same way, if you already have a 30 - 80 kHz machine getting another one adds no real capability per se. Better then to get a mid frequency or a big gun.

For people who have never had a high performance VLF looking at their very first one, I should hope the reviews point out the obvious advantages that the Gold Monster 1000 offers them, especially when operating in very difficult ground conditions.

For me a properly set up Auto GB is a must on a VLF especially a high frequency VLF, no matter how quiet the ground is the ground will always vary as you move about. I tested the GM 1000 alongside the GBII as well as a Macro Racer, the GM and GBII were very quickly short listed to top spot (I've also used the White GMT in my test area so know how they behave). The big winners on the Monster for me were the silent threshold (surprisingly because I'm generally not a fan of this type of thing so approached the Monster with a sense of trepidation), Auto GB ( A must in my areas) and top of the tree the Auto+ Sensitivity control.

I would love to see the GBII brought into the modern world, its amazing to think its been out for so long without any major changes. Going back to the GBII took effort because I was constantly on the controls adjusting the GB and could only do away with hot rocks by using the Iron Grunt. Interchanges in the ground also gave me trouble whereas the Monster just happily tracked these obstacles out and a simple press off a button to disc mode handled the more positive hot rocks. Simply from an ease of use situation the Monster won the day, even though the GBII has the edge for sensitivity a lot of that advantage was lost due to ground signals constantly getting in the way.

Put it this way, if Steve and I were both using GBII's in my areas, he would thrash me in the gold take because he is a far more savvy VLF operator that I am (He truly is a wizz with the GBII, absolutely blew my mind what he could do with one, even in the nasty ground). If Steve had the GBII and I had the Monster I honestly feel I could hold my own and maybe even pip him at the post. Obviously this is in areas I work because I've never worked a VLF in the States before. 

BTW the areas I have been testing in are considered very mild by Australian standards, I used to use my Whites GoldMaster II in these locations with a concentric coil for a living 20 years ago, in some places I could even Max out the Gain.

I was wondering apart from size what are the trade offs or avantages for using the different size coils or there going to sense just the same With area covered to being able to fit in tighter places

      Hi guys, Headed out for 3 hours late this arvo to the spot where I left off on my last little finds with the GM 1000. In amongst the exposed bed rock schist that the old timers had sluiced down to & also in & around their tailings races. Didnt take long to get the first little hit on the drop off down in to a tailings race.
      Scratched it out of that crevice on that little ledge

      The next signal was down about three inches & I thought it was going to be bigger than it turned out to be.

      My next signal was in the exposed bed rock on the top edge of a tailings race or drainage channel that the old timers had carved out of the solid schist.

      A few scrapes & the signal was out

      It wasnt long until the sun would be going & I hit another signal just as the sky lit up in to a beautiful sun set. The signal was a small piece of gold.

      And the sky was a beautiful gold as well. Time to pack up & walk out.

      All up 5 tiddlers for .34 of a gram Deep All Metal Mode & Manual Sensitivity on 10.

      Cheers guys.
      Good luck out there

      I know it is really early in the bout. But possibly is the new kid on the block going to knock out the reining champion of many many years in the gold nugget VLF sport? 
      I'm hearing so many good things about the GM 1000. And I'm really leaning on getting one soon. Hearing so many good reports from " Average Joe" dectectorists. 
      I have had way more experience and success with Minelab detectors than any other brands. So I guess I speak Minelabbian better than anything else. 
      My gut feeling thinks that we might be crowing a new Welterweight Champ. 
      I guess time will tell?????

      One of the guys at my workplace has been tagging along on some of my recent gold trips and has thus been inspired to purchase the GM1000 from a local dealer as soon as it became available.
      As a first outing we went to a claim I am a partner in for some detecting. We went as part of a group of 5 that had 4 different types of detectors with them. We have detected this river claim extensively and unless there is a flood that moves some material and exposes bedrock we don't find a lot anymore. Consequently we often dig by hand and scan the bedrock that we expose to recover the gold.
      Once at the claim three guys got to work digging a hole while myself and my friend with the GM took off up the creek in order for me to teach him how to use a detector. The plan was for me to use the GM1000 for a while and get him to watch me work while I told him what I was doing and then gradually hand over to him.
      First gold came after about two steps in a bedrock crevice. I had detected a small nugget in the same crevice before on a previous outing but obviously the GM was more sensitive and had managed to find something. There were two tiny prices in the crevice. We continued up the creek and found a few pieces here and there, all were small to very very small. Some bits well below 0.1g.
      After about half a dozen bits I left my friend to carry on on his own and joined the other three guys with digging the hole.
      After a couple of hours the man with the GM returned successful, he'd found his first three pieces of gold and was very happy. After that I got my hands back on his detector and found more pieces up and down the creek.
      The main points of interest with using the GM1000 I found are;
      #easy turn on and go operation
      #very sensitive to small gold
      #light weight
      #quite reliable ferrous / non ferrous indicator
      #lack of threshold easier for amateurs to interpret
      #clear signal from targets
      #excellent pinpointing
      #picks up hot rocks
      #signals when entering water
      #sensitive to coil and coil cable banging (although, what detector isn't)
      Generally I think this detector is a top performing VLF that is ideal for hunting gold in bedrock crevices or other shallow ground. Ideal for getting the last scraps from gold producing areas. Not so good for outright depth or areas with a lot of hot rocks as, despite the ferrous indicator, they still make a signal to burden your ears. Much of the gold that we got with the GM seems to have been quite small and other detectors simply missed them. We were calling these pieces monster flakes! 
      Detector was run in maximum sensitivity in the deep / all metal setting. Bedrock is generally un-mineralised with isolated bands of noisy rock. 5 inch coil was used.And the total loot in the picture below, biggest bit is 1.39g (found with SDC2300 but anything could have found it). All but I think three pieces were found with the GM1000.
      If you have any questions I will do my best to answer.

      Greetings fellow prospectors! For a more than a year I have thought about doing up some Youtube videos on prospecting and I have finally gotten off my backside and done it! This is the first video of a 3 part set where I will be taking a look at Minelab's new Gold Monster 1000 nugget oriented metal detector. This part one video is an introductory discussion about its various features and settings. In the next couple weeks I will put up part 2 which will be on testing the GM1000 out in the field and then part 3 will cover some practical suggestions for prospectors on getting the most out of your Gold Monster 1000 and a discussion of some of the best kinds of places to use the GM1000. I will publish those other parts soon, but for now, here is the part 1 video. The quality here may not be perfect, but there is a lot of good information and content in this video. Additionally, now that I have the ball rolling you can expect other videos on different prospecting topics coming later once I have completed these 3. - Chris

      Hello everyone..  
      Im rookie starting out gold prospecting with a metal detector. I have always dredged for my gold and wanted to give metal detecting a go.
      So i have gotten the GM as my first gold prospecting detector and i would have to say im very impressed. Im happy with how simple it is even in our hot soil here the Dominican Republic.  
      I had to switch from deep all metal to "Gold Mode" most of the time because of the ground noise.  
      But it was manageable for a rookie like me just walk everywhere and just detect.  Found a couple false signals but they was like pockets of black sand they appear while scraping off the overburden to reveal more the signal.  
      So i have went to a place where some lady just walking by found a piece of gold since i dont know of no place here where people would metal detect since no one do nugget shooting with a prospecting machine. After about like 10 minutes i got a good signal and i dug my first gold nugget about 4" down. It weighted in at 1.4 Grams.  After trying to search the are for 10 more minutes and not founding nothing more i left since it looked like it wanted to rain. 
      So i have found my first place where i know i have found shallow gold. Hope i could start now a list of these deposit to revisit when i have a PI machine .

      Hi guys. This is my first ever bit of video footage I have ever done, saved to youtube & then had to cut, edit, & merge 4 different clips together in to one. So not sure how it will turn out.
      Footage is of a couple of targets I got using both the Gold Monster 1000 & the Gold Bug 2. I didnt mention in the footage the Gold Chance Indicator & what it was reading but you will notice that as both targets were non ferrous it was indicating to the right quite strongly. Even when the GM 1000 was in iron reject it was still giving an audio signal as well as indicating to the right. If it were iron then there would have been no audio signal & it would have signaled to the left.
