  1. Need Help With Possible Meteorite ID

    Ya know, that's something I hadn't even considered. I appreciate that idea. It sorta looks like it was formed in rock. I guess I should do a specific gravity test on it to start with. Right now, though, all my time is spoken for. But, that's something I should do this winter. It's also too big to weigh on my little Gem Pro 250 scale, too. Jim
  2. Need Help With Possible Meteorite ID

    Yeah...I hadn't even thought of that, but the wife mentioned it while looking at it last night. So, I naturally thought.."I know just where to ask"...LOL. I first thought it was from the firebox of a locomotive, but there's no way that would be hot enough to melt iron or steel. It was found about 100 yards from the tracks. There is quite a bit of junk laying around that area. I think that stop was sort of a track maintenance place. There are cinders along the track there for a ways. There's no water available there. That track originally ran up to the town of Mackay where there was a substantial copper mine, and also serviced the gold and silver mines in Montana, and the Idaho area around Salmon. Now it runs out to the Idaho Engineering Laboratory. Jim
  3. Need Help With Possible Meteorite ID

    It's not actually rock, Fred.....it's solid metal, though I am definitely not arguing that it's a meteorite....I have no idea what it is. Jim
  4. I guess I'm as big a moron as all the other meteorite wannabees, but here it is. I found this hunk of metal out in the Idaho desert. It was in the vicinity of an old railroad stop. That railroad dates back to the late 1800's, and that stop was abandoned long ago. I figured the rock had something to do with the railroad, but looking at it the other day, I started wondering. I had it checked at a local scrapyard a couple of years ago, and the gun showed it had +/- 10% nickel. It will cause a round magnet to roll around. It's about 2" across at the widest point. What say you experts? Everything I know about meteorites could be written on the back of a postage stamp, with room left over. The closeup pic is a small broken face. We ground a flat spot on one side so the xrf gun could get a reading. Jim
  5. Couple Rocks

    Interesting how one man's rarity is another's common find...LOL Jim
  6. Couple Rocks

    Really nice, Bob! From what I've seen in Wyoming, and Idaho, blue flourescence is fairly rare. That "tube" nodule is also a special find. Jim
  7. Concentric Vs DD

    Good info, Steve...thanks1 Jim
  8. Makes Ya Think

    John, that trap Kiwi showed, and the one I found are leghold traps. They're not designed to kill, they're designed to close on the leg, and as the leg is pulled up, they're made to grab whatever they can...usually toes. What Fred said is the truth. I'd love to find one of those old grizzly bear traps, with the big teeth. That would be worth some bucks. Jim
  9. Makes Ya Think

    Last winter, I was exploring the McCullough Range in southern Nevada, and found a double spring # 3 Victor trap. Probably set for coyotes back when they still allowed grazing in there. It was on the edge of a drywash, and probably drug there by the critter. Still had the stake and chain attached. It was on top of the ground, so I didn't have to worry about getting "bit"..LOL It still works, too. Jim
  10. Using The GMT To Find Black Sand Paystreaks

    You can count on that. I got tangled up on another project, and ran out of time on the black sand thing. Hoping to get back at it soon, assuming the weather doesn't get me. Jim
  11. Using The GMT To Find Black Sand Paystreaks

    Chris, the only real use I can see for this feature is trying to locate pay streaks of flour gold. That's what I really wanted it for. I live very close to the Snake River, and the river is full of very tiny flour gold.....the amount is estimated in the billions of dollars worth. Because of its shape factor, that flour rides well up in the water column, and is deposited on the surface as the high water goes down. The follow the black sand feature could be useful, if it worked, to find those surface paystreaks. As far as finding deeper larger gold with that feature, I agree with you...not much benefit.
  12. Using The GMT To Find Black Sand Paystreaks

    LOL...yes, John, they did. And I've still got my old Garrett Master Hunter BFO, with two double coil sets for it. Jim
  13. Thanks, Chris. I was under the impression that while you might see through one, you can't read text or see a straight line through one. Jim
  14. I'm with Chris. A simple test is to look at at text through it. Or even a straight line, or some sort of edge. If you can see it, it's not a diamond. You can't see through diamonds. Also, it doesn't have the luster of a raw diamond. jim
  15. Concentric Versus DD Coils On White's MXT

    John, the RNB packs for the GMT, DFX, MXT, etc. are 3-cell packs. max voltage is 12.6...perfectly safe in those models. RNB doesn't make a 4-cell pack in that configuration. To my knowledge, the only person making, and selling the 4-cell pack is Reidman. You defintely don't want to put a 4-cell pack in the aforementioned detectors, but it works terrific in the TDISL. Jim
