  1. I'm using the GPX shaft and coil mounting hardware on my Gold Monster. The telescoping shaft has always been a favorite of mine; since I'm a shorty, I can adjust it to just the right length. And instantly collapsing it to easily fit in the truck cab is a plus.
  2. I'm thinking about coming up your way for the eclipse.

    Will you be watching it and where?

      Sorry Mitchel-it's on a Monday and I'll be working. I believe the full eclipse zone is a few hours south of my locale.

      Ok, I didn't know how close it was.

  3. Hey that's exactly what I thought too!😀
  4. Minelab sent one to me after I purchased a GPX detector a while back - was a total surprise. I use mine at the soils and aggregates lab here at Allwest Testing & Engineering, where I work during the summer months.
  5. Great finds Randy, congrats!
  6. I should also add that when up close and personal with a large metal object, the Monster emits an overload alarm similar to that of the Fisher F75...a surprising feature that I was not expecting.
  7. I found the Gold Monster 1000 to be extremely sensitive to a wide range of nugget sizes and types of gold, with a definite edge on depth in mineralized ground - for a VLF machine, anyway.
  8. No worries Fred, the Monster loves species of all types too.
  9. The only reason I can think of to ever use the iron reject search mode is if the area was just chockablock with iron trash.
  10. I used the 10x6 ellip while hunting meteorites for better ground coverage, and mainly the 5 round for the gold; I was targeting patches that I have already gridded with the GPXs, SDC, GPZ and GB2 to see what, if anything, was left behind for the GM 1000. The 5 round coil has more sensitivity to the smallest gold particles that the Monster is able to find, so I wanted to have that edge.
  11. I recently had the very fortunate opportunity to use the Minelab Gold Monster 1000 for 30 days. During that time, I was able to discover the nuances of the machine that, like any metal detector, can only be fully realized by logging lots of hours behind the control box and investigating lots of targets. In Steve's excellent review, he has covered most of what the GM 1000 is capable of doing, as well as the features and functions of the machine, so I will not rehash those here. Instead, I will relate my experiences with the detector and its unadvertised abilities that have come to light during my sojourn with it in hand. I first powered up the Monster at Rye Patch, Nevada, and after a very brief automatic frequency scan, the unit emitted two short beeps, signaling that it was ready to start swinging with no pumping of the coil or ground balancing necessary...nice! The first thing I did was to bury a small 3 or 4 grain test nugget a couple of inches into the damp alkali soil, so as to fiddle with the manual and automatic sensitivity settings in order to find the most distinct target response. Right off the bat I noticed there was no audible threshold...a little unnerving, but I decided to just roll with it and trust that the engineers at Minelab know what they are doing. In all-metal search mode at low sensitivity settings there was no response from the conductive damp alkali ground, and very little to no response from the tiny test nugget. Increasing the sensitivity to 6 or 7 made the nugget start popping much better, but some slight feedback from the ground was also noticeable. At a manual sensitivity setting of 10, the conductive alkali response was overwhelming, but as soon as I increased it to 11 - which is the first automatic sensitivity setting - the screaming ground response completely disappeared and in it's place was a crisp, clear target response from the test nugget...very impressive. Advancing the automatic sensitivity to 12 (auto+), the signal response from the test nugget was even louder and more intense, but there was also some ground response as well. I decided why listen to ground noise when the test nugget is plenty audible at a setting of 11, and went with that. With any new detector, I dig every target, even if reads 100% ferrous, just to familiarize myself with how the machine responds to various different targets. The few hot rocks that signaled on the Monster, both positive and negative, completely pegged the gold chance indicator all the way left into the ferrous zone. Soon I was finding extremely small bits of foil, lead and iron. Then I started to notice something quite amazing to me; the iron targets - even the tiniest ones - were making a subtle "boing" type of a response like a negative hot rock, whereas the nonferrous targets were more zippy and lacked that subtle boing quality. After a while, I found that I no longer needed to look at the gold chance indicator to determine whether a target was ferrous or not, just by relying on the sounds; I was really starting to like this detector. Then it happened: a fairly strong response that was pegging the gold chance indicator all the way right, into the non-ferrous zone. After digging a couple of inches, out popped a beautiful little crystalline nugget weighing a mere 2.4 grains - the first Monster nugget! With the northern Nevada weather being uncooperative and still quite wintery, I headed for the sunny warm deserts of Arizona. First stop...the Yucca Dense Collection Area north of Lake Havasu City, formerly known as the Franconia meteorite strewn field. VLF machines make the best meteorite hunters, and the Gold Monster 1000 did not disappoint. I took it to an area that is carpeted with basalt hot rocks that make it extremely difficult to operate a VLF while retaining any shred of sanity. The Monster was incredibly noisy in auto sensitivity, but adjusting it manually to a setting of 4 mellowed it right out and within 5 minutes the detector nailed its first space rock! and then another a while later... Although finding meteorites is fun, the GM 1000 is a gold nugget detector after all, so it was on to the famed gold fields of Quartzsite, Arizona to see what the Monster could do in beat up old patches that have litterally been detected by hundreds, if not thousands of detector operators. Well, suffice it to say it didn't take long to find the first sub-grain speck of gold. And another... The ground in Quartzsite is much milder than the alkali rich soils of Rye Patch, but has lots more hot rocks including magnetite, which is super hot and very magnetic. As I was detecting an old nugget patch littered with these super strong magnetite hot rocks, I decided to see how the Monster responded to them; waving the coil over one resulted in a very sharp and intense zip-zip. Slowing my sweep speed to see if the signal would broaden, I slowly raised the coil an inch or two above the magnetite to see if the signal would drastically decrease in strength (an old VLF hot rock identification trick). Slowly lowering the coil back down above the rock, I was suddenly incredulous at what I was now hearing...absolutely nothing! The Gold Monster had completely tracked out a magnetite hot rock! I placed my test nugget right up against the magnetite and was stunned to hear the nugget respond loud and clear, with absolutely no interference from the hot rock. Even this guy couldn't hear that hot rock: I also found more meteorites in Quartzsite with the Gold Monster...the full story here: In my limited time swinging the new Minelab Gold Monster 1000, I can definitely say that it is unique and can do things that I haven't seen from any other single frequency VLF gold nugget detector, all in a light weight simple to operate and competitively priced package...kudos to Minelab!
  12. Aside from having fully automatic operation, it looks like the thing that makes the GM 1000 unique in the gold nugget VLF market is it's sensitivity to a much wider range of nugget sizes and depths than any other single frequency VLF gold machine.
  13. The processor is also mentioned in the GM1000 brochure.
  14. Ace! Well done Dave. Let us know how much gold the spgr test reveals.
