  1. Hi Steve,

      Love my 22" X-coil for the GPZ 7000. Made my own adapter, was easy to make, hardest part on it is probably burning off the red coating on the wires to get the solder to stick 😉.. But so far love it...

    P.S. the adapter Minelab has on their coils looks like a double high speed switching diode, part # PMBD7000, in a SOT-23 package. The diode has an SMD code on it W5CAG.  More than likely a crypto chip, as they make the Crypto chips in a SOT-23 format also.

  2. Like JasonG,

     Spurious signals and trying to concentrate on them , messing with different settings were taking up much more time, than finding nuggets to me at one point. Upon talking to others, I then tried the Steelphase SP01 amplifier/ filter. All I can say is wow !!!! It became the holy grail to me, and I dont leave home without it. Not only did it clear a lot of the interference, for me, but I can pump a little more volume into me ears for those slight threshold breaks. No more headaches from after a day of detecting with my ears jammed with white noise. Now this is just my opinion, and am noway affiliated with them....

      On the Steelphase for the GPZ7000 I use the following settings. Mode 2, Volume- set to how you want, Filter- 1.

       I have done several tests with the Steelphase and without to see if Im missing targets, and have been impressed, as it was allowing me to hear those faint threshold breaks, without all the interference. Would love to try experimenting with it with the aftermarket Z and X coils...

  3. Pretty good info thanks Steve, looks like a lot coming out for minelab, now I would love to incorporate the MDS-10 PI with GPR to see the contours of bedrock, look for those low spots where gold accumulates. There is a lot of new detectors coming out. Here is the link just for the countermine detectors. https://www.minelab.com/usa/countermine/detectors

     Also check out the F3 UXO - Multi Period Sensing technology into Minelab’s new BiPOLAR technology. 😳

    There used to be a wider selection of decent metal free boots but I'm having trouble finding anything these days which meet all my criteria. I also use my boots for work, general mining/prospecting, and daily use. The Reebok/Converse ones used to be the gold standard but their quality and comfort has declined and they are too large/clunky for daily use. They used to be more comfortable to me than actual hiking boots but now every pair I buy has pressure points that never go away so I've given up on them.

    If anyone knows of a boot that fits the following criteria I'd be interested to try something new:

    • Fully leather and 6-8" high for snakes/general sharp thing protection
    • Composite safety toe for working around heavy equipment, falling rocks, kicking stuff out of the way, etc
    • Side zip or slip on for easy off/on daily boots
    • Light colored such as tan, sage, or at least light brown and not black for desert/heat use
    • Not overly puffy and large like the Converse's, nice enough to wear with normal clothes

     

    I use 8" Reebok Rapid Response boots, 100% no metal, got mine with composite toe. The side zipper model, which I own, has a metal zipper tab, which I remove. The boots last on average 2-3 years, but are used a lot. They are light weight, and in summer when its 115 degrees they do pretty good keeping feet cool... If you hunt in desert environment, waterproof, or snake proof boots I would not recommend, at least for me, as my feet would not breathe in them, sweat big time, get athletes feet, ect.

         I also put an impenetrable insert in them, as the cactus still come through bottoms sometimes on any boot, especially the chollo. Make sure to get non metallic, a lot out there with metal in them, such as

  5. The south side produced some large pieces, back in the day. Nowadays it's really hard to find any on the south side. The north side extends quite a ways up, and smaller pieces are still around, including small irons like Mitchel said. I am enclosing a picture of the meteorite strewn field extended from Jim Smallers original map, this map is a few years old, a lot more have been found since..

  6. Allen,

      Havent been to Franconia since the beginning of the year, but get out there at least 2-3 times a year. Fun place and always produces meteorites, along with .50 cal, .30 cal, bits of wire, ect. Still pretty warm there now, suppose to be about 114 this weekend there. A friend about a year ago got a multi pounder out there, so there still there, just not as many.

    If you get out there hope you get some good ones.

  7. 1515Art,

      Those are great guns, but not really detecting all day with the GPZ, in my opinion. I bought a Glock 22 Gen 4 (.40 Cal) when they first came out and carried it detecting. You had to carry it up high, like you have to,  or it set the detector off. It was just to heavy and bulky for an all day detecting gun. Did have to use it once while detecting down by the Arizona border years ago, while being shot at out in the middle of nowhere... I ended up switching it out for a smaller conceal and carry 9mm. So much lighter, easier to deal with.

    Reminds me of this guy who mounted a military grade mine detector in front of his jeep and drove through the washes in the El Paso mountains (So Cal, Randsburg area). He found one of the largest nuggets ever recovered in CA ("Mojave Nugget) several feet deep. That was in the 70's...The unconfirmed rumor goes it was Jim Straight. Perhaps some unconventional techniques like that are worth wile thinking about? I suspect no hand held detector would have caught it at that depth.

    Gold Catcher,

      The Mojave Nugget was not found by Jim Straight, but by Ty Paulson. Jim Straight knew Ty Paulson, and was prospecting in and around the Randsburg, CA area at the same time. Jim Straight in the ICMJ November 2004 Volume 74 says Ty Paulson found the Mojave Nugget in Benson Gulch on the ridge to the right side of the gulch, which is part of the taft prospectors claim, just south of PCSC (Red Chispa) claim. There have been some pretty good size multi ounce nuggets pulled out from the Red Chispa Claim, and to this date still are every now and then.
