  1. I posted on Robs forum about the upcoming events re the Pomona gold and treasure show and I have been hoping you will as in the past add the needed details. I will be there on Saturday pushing my wheel-chair and I hope your father will be in your booth as last year. I also know You and Bill Southern as well as others will be presenters on various subjects. To get to the point, I just started the post and without others joining in such as you have in the past it will be limited... Mackay was a Miner... jim
  2. Over the recent years I have noticed more interest in two-box detectors. Since the receiver and transmitter searchcoils are separated, their depth capabilities are to be measured in feet instead of inches. They work because they measure the changes in conductivity under the receiver "box." Their depth depends on the mineralization of the soil and the size and shaped of the conductive soils. Back about 2010 on another forum I was bashed by claiming depthjs of three or more ffeet to locate concentrations of placer gold.within the metaliferous dry south-westerm deserts. The method is smple, just use a two-box to seek concentrations (pockets and channels) of magnetic black sand; but to be fair, as I did not mention I was using my vacuum-type two-box instead of a conventional detector and being ruthlessly bashed I picked up my marbles and that was that. However I was using this method.... crude I will admit, but by virtue of free-milling placer and magnetic black sand being "bed-fellows," I was able to trace-out magnetic black sand concentrations that carried eluvial placer deposits. Like a bolt out of the blue, I became aware of the relationship of regional geology to the types of placer deposits. More later, I got a lota backyard cleanup to do and I is slow as I use a walker; but it is great to be out and about...Off subject... Hey, Chris if all goes well I will be in the Valley Prosepectors booth at GPAA gold and treasure show n Pomona Febr. 20-21 and looking forward to seeing you and your dad... jim
  3. Bill If seeking for lost gold mines and treasures is what you like to do; go for it. You could find it while others miss. And it could be in the cards you will be even if you miss the one you are seeking; you could find a heretofore overlooked one.
  4. Chris the main problem about the T2: No serial number and if a fake was sent in for repair it was difficult for Fisher Repair to handle the volume and separate the legal from the clones w/o a registration card on file... So the original green T2 was quickly revised to a later T2 and no longer manufactured,,,, Now time has passed and the green T2 is back and First Texas is getting rid of its backlog of inventory... Although it was in 2006; today it is not outdated as it has Grab, Barograph and phase numbers and the standard open spoke 2D 11-inch and five in sniper coil... So in many ways I'm happy to have one of the first off the line even though mine has not a serial number but has been authentised and updated as I have sent it twice over the years; once for the bottle cap revision and again when the control-stem broke off the handle... Even tho I paid more for my T2 in 2006 then the current $499; I'm one happy camper to have been able to use mine in seeded TH hunts as it is fast recovery; but alas I'm now just slow and use a walker.... But positive and happy with memories of getting out and swinging my original non-serial numbered green T2... Hey, I just got my California driver's license renewed for 5-years and I do not need to wear glasses and the license expires on my 91th birthday. jim
  5. Chris my Vacuum tube two box needed a dry-cell in both the transmit and receive box. Each drycell Rayovac BA-51 were 67.5 volts and lasted about 9 hrs. It used highvoltage and punched down deep... as far as raw depth about as good as the Gemini-3 but mine lacked the refinements of the later transistorized Gemini's. But I have quite a story to relate... but I struggle to write a good article; but it could be a good article... jim
  6. Bob... Please no more about your friend... We need to talk... jim
  7. A great place to beep for electrum float nuggets was in the National Mining District in northern Humboldt county... 50% gold/50% silver by volume. However it may now be being heap-leached?
  8. This is a very unusual topic with over 2,500 views and five posts. Both Chris and Bob sum it up geat. Back in the late 1959s- EarIy1960's I lived in Lovelock and worked for Eagle-Picher and did some prospecting with Garry Eden and Drywashed with A,H, "Scotty the Assayer" Scott. So with this in mind I thought I would add a little history. The Majuba Hill/Mountain placers are extensive and cover many square miles westerly of Rye Patch reservoir and easterly of Majuba Mountain. Both the placers and their sources are expansive. Majuba Mountain has been mined for cinnabar, tinstone, electrum as well as gold and traces of many other metals and their elements. Thus to add to the mix the physical and chemical weathering over centuries of normal and diverse weathering patterns have created various basic types of gold placers: Both Eluvial (dry) and Alluvial (wet/stream) placers. They blended into each other adding to the mix: Bajada (alluvial fans); plus Pediments and Eolian placers and other diverse soil types. The placers were said to be discovered as early as the 1930s Great Depression years and the sagebrush roots were panned. Other drywash recovery methods were used. It was said that nuggets were specked during a foggy or rainy period by their sheen when wet. Beginning in the early 1970s, the TR and VLF metal detectors; and in the middle 1990s, the PI's, all have really "pounded" the area, However both Chris Ralph and Bob Thomasson sum up Rye Patch Gold. And Idaho Al mentions he is finding gold there. So it could be that Rye Patch is one of the best known placer gold fields in Nevada?
  9. Thanks Chris... It sure looked like I needed to diet... camera angle :rolleyes:.... Bill, I reckon the lost adams is named because it is lost... But You are not lost; thus I sense you have a couple of great stories to relate if you have a mind to do so. And for sure I would be delighted to read one.
  10. ICMJ Associate Editor Chris Ralph: (Chris, I mailed you a photo of me using my 1946 vintage Fisher Metallascope as my photo on this forum... I would be most appreciative as I can no send photos. It is legal. George Shields took it and Chris Gholson gave me permission to use it; ref pg 139 in his co-authored Rich Hill) I did pretty good with this vintage/obsolete vacuum tube type that needed expensive high-voltage primitive carbon type battery packs that were needed to drive the 5-tubes two-box deep... yards (feet)... not inches into the sub-soil formation while seeking a conductive hard rock vein, that I failed to find I was most successful in locating large concentrations of magnetic black sands that are often associated with placer (gold,electum,silver) deposits due to both having a higher specific gravity... Depths 3 to 6+ feet; usually on a caliche, hardpan or other bedrock. For a buried 50 gallon drum up to 10 ft or more; but who in their right mind would spend the effort to dig a deeper hole unless it was tossed into a vertical shaft. For treasure hunters My original metallascope was NOT senitive to raw metal less in size as a trashdump of buried cans that were into a shallow shaft up to say 9-ft deep. But the Fisher Gemini 3 is great to locate a can or even a saddle-pouch of buried loot. Quart size canning jars filled with coins been said to have been found at posthole depths of three to five feet...
  11. Chris... All I know, and remember : the original 2006 T2 (Texas) manufactured ones were suddenly bought out by dealers who were getting orders to fill and even those such as me and others who were posting on open forums... (you should remember finds-forum (not findmall) and I was offered $2000 USA for mine if in operating condition... but naturally I did nor sell it.... So, I guess there were a mix of both good and non-good. But it was such a problem FT decided to discontinue the non serial # 2006 Teknetic T2 and replaced it with a later serial # T2 "'deluxe-named' edition" I'm truly glad you have been to Africa; this makes you AAA (Alaska-Africa-Arizona) For me it has always been a big trip to drive of fly stateside.
  12. Bill you are correct; but still do not count out the Gemini 3 for locating and mapping blacksand concentrations; but back when I was using the Vacuum tube Metallascope it used large high voltage batteries to power up the tubes and as you know there are still advantages the tubes have over transistors and I punched down deep and if in a metallogenic area the blacksand was most likely associated with placer due to its gravitational association. Changing the subject if you are lost adams Bill you could be looking on the wrong area. But I have no idea where it is; just where it ain't... jim
  13. Chris, I bought one of the first T2's off the line in 2006. As you mention in an earlier post in this thread the T2 was cloned; but here is the rest of the story. The clones worked great in Africa and it was an understatement about how many clones were made... The T2's did not have a serial number! The T2's worked great in the African gold fields and FT was playing it cool and needed to get a handle on the problem so they offered a bottlecap revision for those that were using the T2 in coinhunting. I was using mine for nugget hunting as it had bargraph and phase readings... It lacked tracking and had a grab which back then was not understood. However I asked a lot of questions and finally understood a little about it as it was digital and different than the analogs. Since I was also using the T2 in seeded coinhunts I sent it in for the bottlecap revisions as well some other hardware problems... This plus my warranty protects me from the ubiquitous clones... Teknetics soon stopped making the original T2. However, time has marched on, I understand FT has a bunch of T2 stuff gathering dust and are now assembling the T2's again. Price $499 which is a WOW... The T2 is a David Johnson and Ol' Dave is years ahead of the completion and a good guy too. I have known Dave since the 1980's when he first went to work for Fisher Los Bano's. Now for the rest of the story I introduced Mr. Scott Harn and Dave at a Federation event at Laughlin. Mr Harn had one of those newfangled cameras with a card holding hundeds of photos; he took several of Dave and I... Dave has been, and still able to beat Lou Gehrig's disease known as ALS since the early 1990's and has written a published book about it... It would be nice if Scott has saved the photo card. As I remember he was on one of the basketball teams and was in a game while at Laughlin,,, It was with a Police dept and Scott was one of the best players on the team. Jim
  14. Chris... to cut to the quick... I acquired a vacuum tube two box that originally belonged to the Utah State Collage and was sold as surplus. It was manufactured in 1946 and used high-voltage batteries to drive 5-vacuum tubes... It is a direct descendent of Dr. Gerhard Fischer (Fisher) original 1931 Metallascope and patented in 1937. With the development of Transistors in the 1950s; it became known as the Fisher M-Scope Gemini-series. My vacuum tube two-box used large-size, heavy and cumbersome high voltage batteries. But depth it had, and I was able to detect magnetic black sands at depth. Black sands are often associated with placer gold if in a metalliferous area..... Also the two box could be useful to trace out condictive metals.... Unfortunately the batteries we now expensive and the vacuum tubes in high-power drain them fast. So I used it spairnly and they were special order in a cardboard rectangular box with a short shelf life. One box was the transmitter and the other the receiver..jim
