    New Detector

    Have not seen any of these in Aus ,but it is a BFO detector that would date from the late sixties to early seventies. The manual is probably still available on the net . regards PM🇦🇺

    Equinox Options

    After reading reports of the abilities of the Equinox 600 in multi against the 800 I was wondering if anyone has used the 600 for hunting small nuggets as I’m looking at a new general purpose detector that I can loan to friends on occasional prospecting trips , although I’m figuring a 6 inch coil would probably be required also . regards PM🇦🇺

    I’ll check it out .

    Hand Held GPS

    A lot of us detect in areas where phone reception is poor or non existent and most phone apps require some support from the network ,hence the necessity for satellite guidance systems . I use the Garmin units and find them easy to use and reliable. The e trex units are economical units for waypoints and basic breadcrumb trails or you can upgrade to the mapping units .

    Doing The Monster Mash

    Nice report JW and great pics too . Good to see the GM getting some use just don’t slip off one of those edges. I,m guessing the snow is not far off as it is very cold in Sydney PM🇦🇺

    Need Help Guys Asap

    Here in Oz the SDC has a reputation as a rock solid performer on small gold in mineralized soil . But that doesn’t mean it’s going to trump a good high frequency detector under all circumstances .i think there’s been plenty of opinion on this forum about the ability of vhf detectors to out perform Pi models in mild soils . I have met many owners of of the SDC in Australia and not too many who want to part with them . I tend to find much smaller pieces with the Gold Monster than with the SDC but at a much shallower depth due to our difficult soils . In milder soils the comparison may be a lot closer.

    Deep Lead Mullock Heaps

    I think the condensed answer is this , if it’s a small scale deep lead mine ( worked by a small group or syndicate there’s a chance of dropped or missed gold around the mullock and loading piles , on the other hand if the heaps are very large and extended you can put this down to large company deep lead mining and the chance of finding gold on these processed heaps is slim.

    Deep Lead Mullock Heaps

    Deep lead mines usually only processed the pay dirt that was considered profitable a certain distance above bedrock ( in Australia that was 6-12 feet and the rest was discarded onto the mullock . So whilst there is the odd chance there could be a unknown middle or upper level streak the miners discarded , that chance would be fairly low . There are miles of large deep lead mullock heaps in Creswick near Ballarat and they are mostly sticky yellow clay .The Australasian mine in creswick was Australia’s worst mine disaster . If you can find small scale deep lead shafts the pay dirt was usually loaded on horse carts next to the shaft for transportation to the puddling mills and there was always some spillage . so these areas have some potential for detector prospectors.
  9. From what I have read here the coil noise problem seems to be confined in the main to detectors that are being used in milder soils where users have the opportunity to run the unit into the hot sensitivity zone , the instructions that come with the GM clearly state that using high manual sensitivity settings may not be possible for all conditions and for my areas , and I would guess a lot of goldfields especially in Victoria (AUS) the mineralization is so bad that even Auto plus setting is going to struggle . So for a lot of us Aussie owners the coil noise is not an issue. So for you guys in the US and other milder locations it’s either a glass half full situation or glass half empty. But personally I wish sometimes I could ramp the unit up a bit and put up with a bit of coil noise .

    Battling For Gold

    Just gorgeous country to prospect . I’ve noticed your last couple of posts have not featured either the GB 2 or GM as pinpointers , or your to far away from transport to carry them . Hope you didn’t get to much grief from the cyclone tail last week. Saw some footage of bad flooding up north .
  11. Well the unit certainly protests if you bash them but they can take it physically. I,m a lot more gentle on mine and having the little coil on the GM makes it easier , I guess the coil range and availability will ultimately decide how many current single frequency users swap to the new multi frequency units . I can’t see Minelab making any further units that don’t have multi iq technology
  12. The GM is semi submersible and so has some use in shallow areas up to the control housing. But certainly the equinox can take a full dip , this like waterproof cell phones also has its disadvantages when it comes to useability , some equinox owners are already bemoaning the fact that the batteries are completely ensconsed inside the control unit unlike the GM making it harder to replace or service ,
  13. Having seen the impact chirp technology has had on the recreational marine sounder market I believe this technology in detectors will have the same impact on market preference . As good as the GM is in what it does , it’s a shame that minelab has introduced this quantum shift in technology so soon after releasing the GM . The monster may be a good choice for countries like Africa where ruggedness and simplicity where forefront in market aims , I just think that designers were a bit late replacing the eureka knowing that this technology was already on the table. On the plus side for those of us who have purchased a Gold Monster they do look to have a much more robust design for knocking around in the goldfields, a more convenient battery set up , and a choice of large and small coils rugged enough to bash between cracks and crevices as well as great boosted audio for identifying those small pieces.
  14. There’s only one thing worse than finding the tool you bought at the hardware last week is now half price . It’s minelab releasing a new gold detector and then making it redundant 6 months later.

    Equinox Gold Prospecting Yuma Az

    Yes John the lightly mineralised locations do wonders for the discrimination features , unfortunately the areas I work in make it almost mandatory to dig the material and lay it on the surface before using the discriminator , on my first outing with the GM I found a 2 gram piece at 5 inches that showed as ferrous until it was placed right under the large coil. I’m very envious of you guys in the milder soil.
