GEIGER COUNTER JOHNSON MODEL GSM-10S WITH SIDE-WINDOW PROBE for detecting gamma, beta or alpha radiation HHHHHHHHHHHHHHHHHHHHHHHHHHHHH This Johnson geiger counter works well, and includes a side-window probe on a BNC cable. This side-window probe is less sensitive than pancake probes or end-window probes, but is more sturdy than other types. This geiger device uses two standard D-cell batteries; the batteries are effective for more than a hundred hours of use.     The manufacturer is Wm. B. Johnson Co. of  Idaho Falls, ID. All Johnson geiger counters, and all their components, are made in USA. In 2013, I mailed my first geiger pancake probe to Johnson's suppport service, and they repaired and tuned the probe at a reasonable low price.  The Johnson company began in New Jersey, then moved to West Virginia, and later moved to Idaho Falls ID. BNC PROBE-SOCKET ALLOWS USE OF WIDE VARIETY OF PROBES THE Victoreen SIDE-PROBE is in perfect operational condition. As is true with all geiger  probes made in North America, this probe  operates on DC 900 volts. With its BNC probe  socket, the instrument is versatile and can use any type of geiger probe made in North America: pancake, end-window, side-window, or scintillator probe. AUDIO SOCKET: ALLOWS FULL AMPLIFICATION OF THE GEIGER TICKING SOUND This is a special mini-socket on the top panel of the geiger counter.  Included with the purchase is a five ft cable, to be connected to a powerful audio amplifier system, so that a lecture presentation on uranium or radioactivity can be performed before a large audience.  No other geiger counter has this special feature!         Extras will be enclosed, such as several DVD disks, photos of the uranium rock canyon, published articles about uranium mining, etc. The geiger counter will be a good instrument either for outdoor prospecting, or for indoor use with your uranium rock collection.           $50.00 DISCOUNT IF THIS GEIGER COUNTER IS PURCHASED WITH NO PROBE INCLUDED The side-window Victoreen probe is included with purchase of this Johnson GSM-10S instrument.  If you  already own a working geiger probe and do NOT  want the Victoreen side-window probe, then I offer a $50.00 discount with NO PROBE included. SUBSTITUTE PANCAKE PROBE:  $90.00 MORE Extra charge:  Many geiger users claim that the pancake geiger probe is best:  "Once you've gone pancake, then you'll never go back." The pancake is most sensitive, but also is fragile with respect to high altitude in airplanes or mountainous roads above 8,000 ft. Only ONE probe will be shipped: If you want a pancake probe as a substitute for the side-window probe, then an extra charge of $90.00 will be billed.  (Sale price of the pancake probe is $50.00 basic plus $90.00 extra = $140.00 total). An air- tight plastic protective canister will be included if you pay extra for the pancake probe; this canister protects the pancake sensor against damage by thin air at high altitude via airplane travel, or by highway driving in mountainous wilderness ranges above 8,000 ft elevation.       GEIGER COUNTER WILL BE FULLY CALIBRATED Prior to shipping, I will check and adjust the instrument's calibration. My calibration tools are: (1) Ludlum Model 500 calibrator, (2) Eberline MP-2 pulse generator, (3) Fluke high voltage DC probe, and (4) Sperry high-level DC voltmeter. Calibration involves adjusting the three range- multipliers, and also adjusting the geiger's DC-900 volt signal that energizes the probe.         MAKE AMERICAN URANIUM MINING GREAT AGAIN! If fully developed, New Mexico's uranium mines, closed since 1989, can supply 100% of America's electric power for the next 250 years. The Mount Taylor Mine at San Mateo NM, the USA's richest deposit, is planned to reopen by 2024.  Its uranium  lode, at 3,000 ft depth, is 100 ft to 600 ft thick and six miles horizontally wide (Kittle, et.al., 1967, p174).     BONUS 40-MINUTE DVD VIDEO, NOT FOUND ON YOUTUBE! Enclosed with the uranium rock will be my original DVD video disk produced during March 2017 and July 2019. This 40-minute video provides a narrated tour of the locale where these uranium rocks are found through prospecting. You will see Jurassic Canyon's Northwestern Cliffs, which geologically exemplify the Morrison Formation. The Morrison Formation has been the source for more than half of all uranium ore mined in the past hundred years;  It is also the richest source of dinosaur fossils. The DVD video program is enclosed at no extra cost. (This DVD video is unavailable on YouTube.)   WHAT YOU GET FOR $190.00 PLUS SHIPPING: 1.  Johnson GSM-10S geiger counter instrument in excellent working condition. The glass meter has three scales: counts- per-minute (CPM), mr/hr, and battery. 2.   Three pounds of natural uranium rocks, with 15% giving low-level response, 70% giving middle-level of response, and 15% giving upper-level response. 3. A 6" Fiesta Ware dinner plate, 1936-1943 vintage, with 14% uranium glaze. The glaze color is described officially as "radioactive red,"  but its appearance has an orange hue. The Fiesta plate's activity is at a moderate level. 4. Many printed extras such as newspaper articles, photos, brochures, etc. 5.  Original 40-minute DVD video, "JURASSIC CANYON URANIUM," dated March 2017 and July 2019, showing details of the locale where most of the three pounds of uranium rocks were found.  More than half of all uranium ore mined in the USA in the past century has been found within sixty miles of Jurassic Canyon. (This DVD video is not displayed on YouTube.) 6.  Two or more other DVD videos on uranium-related topics. These may be about the uranium mining industry, historical topics, or atomic bomb tests of the 1940s to 1960s  (recently declassified films) 7.  Two D-cell batteries in the instrument, plus a second new pair. 8.  Photocopy of the user's manual for the Johnson GSM-10S geiger counter. 9.  TWO BNC CABLES:  One is short (3 ft) and the other cable is long (4-5 ft).  Velcro straps are enclosed so that the long cable can be attached to the buyer's wooden pole; this enables the prospector to test uranium rocks on the ground without having to bend over while doing it. 10. FLAT URANIUM ROCK IS ATTACHED TO RIGHT SIDE OF BATHTUB CASE. A strong adhesive glue holds the flat- sided rock to the case.  This rock generates  98,000 CPM activity when measured with a standard pancake probe. The flat rock serves as a test-source, to check whether the two D-cell batteries are functioning okay.      $190.00 plus shipping     SERIAL NUMBER This Johnson geiger counter has this serial number  # 2403. The Victoreen side-window probe (Model  HP-270) is made in USA. It has a BNC plug. The Victoreen side-window probe has no serial number All Victoreen geiger probes were made in USA at Cleveland OH.     NO CORROSION IN THE BATTERY COMPARTMENT Be wary of any geiger counter advert that fails to show a closeup photo of the battery chamber;  Rust or corrosion could make the instrument unusable. This geiger counter instrument has absolutely NO rust in the battery chamber and the instrument is unaffected.   $190.00 plus shipping ROCK HOUNDS: FREE ESCORTED ROCK-COLLECTING OUTING Buy this geiger counter from me, and I can guide you during (free) uranium rock-collecting at Jurassic Canyon, near Grants NM. This canyon,  by far, has the best surface-level uranium rock- collecting in the entire USA.  I have gathered rocks there during 36 trips in the past seven years. Three days minimum; I will keep half of the found rocks. Best months for rock- collecting are April through November. I will supply a reprint of this chapter from Michael  Amundson's 2002 book: Yellowcake Towns: pp77-103, Ch.5: "The Uranium Capital  of the World: Grants NM."     NATURAL URANIUM ROCKS: THE MORRISON FORMATION Possibly, dinosaurs may have trampled on these uranium rocks. These will total three pounds, minimum. They will be a random assortment of  uraninite, carnotite, tyuyaminite, coffinite, or Jurassic todilto limestone. The Jurassic todilto limestone (JTL) rocks have an age of approximately 200-146 million years.  The northwestern cliffs at Jurassic Canyon are part of the famed Morrison Formation, known both for uranium and also for ancient dinosaur fossils.  More dinosaur fossils, and more uranium ore, have been recovered at Morrison Formation rock sites than at any other geological sites in the USA.* Two of my finds  were fossilized skulls of juvenile velociraptor dinosaurs; both are enriched in active uranium.  Some of the enclosed rocks are from the Lisbon Valley uranium region in Southeastern Utah, where I searched for rocks in 6-2017.  Some are from Uravan Colorado, where I gathered uranium rocks in 4-2018 and 6-2021. For shipping, the rocks are contained in metal cans for shielding while being transported, so I may need to swap in other rocks to fit the space available in the containers. *Source: William Chenowith: Uranium mining in the Morrison Formation. Modern Geology, 1998.     $190.00, plus shipping   SIXTY DAY MONEY-BACK SATISFACTION WARRANTY About half the geiger counters sold on Ebay are advertised as, "Untested - No Returns."  I suspect that Ebay sellers who advertise in this way are unloading their dysfunctional junk, and they know it. Why buy from them?  I offer Ebay's best money- back returns during the first sixty days. You can return the instrument even if it works perfectly, but you expected more features. Shipping costs are nonrefundable. SHIPPING COST Shipping will be via UPS-ground. Any overpayment on shipping costs will be fully refunded, immediately after the parcel has been shipped. The parcel will be insured by UPS.
