  1. I’d think the heat would vaporize any organics in basalt or rhyolite before it even cooled off to form a recognizable imprint, it would only leave a gas bubble.
  2. Save even more money if you are looking for a used one - buy the old ‘slow’ version from someone who wants the ‘updated’ one. You’ll be happy, the seller will be happy, and the dealer selling him a new one will be happy too! Win win win! Other than the few seconds lost doing the ground balancing, they’re identical units.
  3. That one is a nice replacement specimen. If nice pieces of opalized wood were not so expensive I would love to get a nice one for my collection. The most amazing piece I saw was not replacement, the original brownish petrified wood material was intact, but it had a thick piece of fire opal draped over the top of the wood, It almost look like it melted over the wood. It was in a museum mineral display. Opal is in amazing looking mineral.
  4. Wow, its really neat how the opal replaces the original material. I’ve seen some beautiful examples of petrified wood wrapped in opal, it was gorgeous.
  5. The Becks is the red hand crank puffer- the one with the Briggs and Stratton motor is a custom one- and probably very loud, but not much unlike the 151’s of today.
  6. Here’s a nice one to look at or if anyone is looking for one. A red Beck original- (its not mine, I just thought it would be of interest to someone who may want to restore it as it is a historic piece of mining equipment from Randsburg) https://offerup.co/pSthSGU05db
  7. I know this is an old post, but if someone is looking to revamp the idea, the UXO guys at the old Lockheed test site I used to work at had one of these and they could detect small stuff with it quite deep- cost the same probably as at least four Zeds too! https://www.vallon.de/en/unexploded-ordnance-uxo/vxvt-magnetometer-trailer Jim Straight liked finding meteorites too, wonder if he ever tried it with his Bismarck coil?
  8. Heavy duty coil cover for the stock SDC-2300 8” coil. It’s heavier duty than the stock covers, and fits nicely. I opened this package to check the fit, but never used it as I sold the SDC. $25 shipped (Check or Paypal OK.)
  9. I recently completed building it and so far I was using it on a basic student designed project with my 6th grade technology students who are currently just learning to use a CAD program:
  10. Welcome David! So what’ve you got there, a basalt concretion? Greywacke with a entrapped basalt boulder? My guess is you saw this on the east side of the central valley along the Sierra foothills?
  11. Did you find one? Let me know if you see two of them!
  12. Wanted: Portable puffer I am helping a friend find a portable puffer like a Thompson. I live in Southern California and he lives in Arizona, so we can both do a local pickup in either state. If you have one for sale or have seen one, please PM me here. Thank you! Anthony
  13. We saw that too- daughter had fun laughing about me on that part!
  14. Fun times! Time to get a drywasher and a vacuum!
  15. Ive been wanting to CAD design and make some cabinetry and pull out shelves for the back of my truck, some wood signs, maybe a kayak and some other fun stuff with a CNC router, but the sizable ones for doing larger projects cost thousands, or so I thought. I found this lower cost 8” x 4” sized CNC router kit called a Maslow CNC and just finished building it: https://makermade.com/product/malsow-jump-start-bundle-kit-sled-router-bit/ It uses two servo motors to pull the router around on the base board with chain, and it’s really precise. There’s even a Z-Axis motor for automatic dep
  16. Those with local knowledge of such places are getting old and are disappearing too. By removing those features from maps, it will not take long for all of them to be forgotten. Pretty sad.
  17. Looks like it was fun, some good food and finds, too. But what the heck is that?!
  18. The greenish tinted minerals in it may be olivene.
  19. All good advice, you are right about the lead, I am getting pretty good at finding smaller and smaller pieces of it! Just counting the days down until one of them is actually the real thing. My trouble is getting a real weak signal and sometimes it appears repeatable and others it doesn’t, I try different angles and then go back to the direction I was facing at first and it seems like it changes. No hot rocks being moved by accident or anything like that, no EMI sources around, so I’m not sure what’s happening there. It doesn’t happen a lot, so I think it’s not something with the coi
  20. Very nice, hoping to find something like that one day! What settings and kind of signal did you get from it at first? I’m a beginner learning the nuances of weak signals on the Zed. In fact, if anyone has a good link for videos with weak signal examples, please PM me a link (because this is off-topic from this post), unless Doug is ok with it. Thank you! -Anthony
  21. Made this slide out frame for a shower curtain. It slides in flush with my short rack on my shell, but you can easily modify it for a full-sized rack and put extra supports using a T connector: Its basically a 1/2” PVC pipe in a 1” pipe, the string keeps it from being pulled all the way out. The 1” pipe is secured to the rack using stainless steel zip ties. A shower curtain or awning top can be attached using eye hooks screwed into the corners and outer side of the frame, and hooks or magnets to attach it to the truck when in use, then fold and sto
  22. - That fly in intro would be a good place to put your title, also.
  23. Bill, You are getting pretty artsy with that drone of yours, I like the small World zoom in intro you have on your GM quick balance video. That’s a nice affect, I haven’t tried any of those special effect functions on mine, but appreciate the way it looks on yours as a intro, good job!
  24. Bill, sorry I missed this! How did it go? Is there a recording link? I was a member of Temecula Valley Astronomers, need to go back, fun times!
