  1. Take My Land Matters with you and/or study it before you go. My Land Matters has managed to implement both the new Alaska BLM & State mining claims systems on the Alaska Mining Claims Map. They even went further by including the State Mineral Withdrawal areas and the State Mining Leases in the mapping.Each BLM mining claim information window now has a link directly to the BLM ACRES case file for that claim.Each Alaska State Mining Claim or Lease information window has a link directly to the Alaska State ADL Case file.Each Alaska State Mineral Withdrawal information window has a link directly to the Alaska State ADL Case file for the Closure Order. http://www.mylandmatters.org/Maps/ClaimsAk/GetMap
  2. For those of you more inclined to viewing instead of reading, Chris Ralph has put together an impressive collection of videos here. He is working hard at it adding a new video every week. Chris is very knowledgeable on various aspects of prospecting and mining with in-depth knowledge on geology. Take a few minutes and check it out. Also check out Chris’ book, Fists Full of Gold
  3. 18/ Understanding “Below-Zero” Accepts I take this term from the language used with the first programmable, digital machines that came onto the market in the 1980’s. These set a benchmark for all others since. Part of the reason for this was because although they balanced out mineralization in the ground, they also examined the iron in the ground to see if there were targets mixed in with it. If you can imagine a scale of minus 100 to plus 100 with “0” being the line between non-ferrous and ferrous, these machines used “below zero accepts”. By this I mean that they were pre-set to examine part of this iron range (usually the first “30”increments) instead of just knocking it out. This created much better depth (by the standards of the day). These machines also had the ability to pick targets from amongst this iron--by hearing it too rather than just suppressing it. This is also the Anfibio’s strength--but with much more overall sensitivity. So what you have with the Anfibio is a very sophisticated level of filtering and processing that: • -first, gathers a full and very detailed picture of what is under the coil.• -then filters this diverse signal down to sort the (quick-responding) consistent parts from the (slow-responding) less consistent ones. This broad, detailed initial “look” at the ground means that the detector can separate out small, deep objects as well as those that are in very close to iron very effectively. In effect the Anfibio is “reaching” down into the iron range to give the machine more detecting power. This also means that desirable targets that are coming in partly within this range are more readily detectable. Things like stainless watches, corroded targets such as long buried brass also respond better than with other machines. The “trade-off “here is that the line between ferrous and non-ferrous is blurred. This is true of all high Gain detectors. Things like round bolts and some of the more solid iron objects can jump up to overwhelm the discriminate circuit. So you have a “two edged sword.” Where you want to get better responses from low conductors such as gold chains and earrings--you can run a lower discriminate and / or first Tone Break. However, when you do this--more iron, steel (such as bobby-pins), and other weak conductors will respond. Rather than an actual ferrous / non-ferrous line, what you have is more like a “firewall”--and as you bring the Discriminate and first Tone Break up--this “firewall” is made thicker. Learning to manage this “rust line” is a very important skill that will let you select targets with more accuracy and stabilize the unit at high Gain settings. A low Discriminate / Tone Break setting opens the machine up to more of this “below zero” range. This comes through in the form of “crackle” and other falses. A higher setting creates a bigger reject block between the two (plus and minus) “sides.” Understanding this--and being able to choose a correct setting is the essence of running a balanced signal--distributing the unit’s power evenly and—by standard, quietly. It’s important to recognize the fact that what a detector does is not to just punch down into the ground and alert on metal. Instead--as described above--it acts to separate ground from metal. What this means is that the iron and ground’s responses form part of the signal. A good way to understand this is to think of all metal signals as being a “peak” in the larger ground’s signal. The more of this low range you want to inhibit (block off)--the fewer targets will be available. (For hunters interested in re-working “hunted out” type sites--opening up this low discriminate range is another option that can be combined with a slow recovery speed (Deep mode) or a faster one (3 Tone) or targeted hunt methods using one of the three Frequency options). Remember--it’s not depth that obscures targets--it’s the surrounding “noise.” The more of this “noise” you are prepared to learn to “hear though,” the more you will find. Alternately--creating a wider, more solid bottom reject block can also reduce noise--allowing targets to “jump” though as with the Beach mode’s high Discriminate setting of “15.” This type of setting can be used either to bring the machine’s processing up above the noise level of difficult ground or salt sand, or to reduce the noise of dense iron and bring up masked signals.

  4. I'm proud to announce my new book on the Anfibio Multi. Had this detector in at some of the worst most iron infested truck grove sites around last year and did really well--wanted to share some of the things that have worked well for me. cjc Successful Treasure Hunting with the Nokta / Makro Anfibio Multi Clive James Clynick is the author of some 25 detecting “how-to” books and numerous articles. In this detailed and informative book he shares his 40 years of experience and instructs you on how to become a more accurate and successful treasure hunter with the Notka / Makro Anfibio Multi detector. Topics include: · Getting the Most from the Anfibio’s Selectable Frequencies · High Gain Power Basics · Dense Iron Methods: Recognizing False Signals. · Coil Control Skills and Methods. · Deep Silver Coin Hunting. · High Power Signal Balancing for Depth and Accuracy. · Mode Change Methods. · Anfibio Gold Jewelry Hunting Tips and Methods. …and much more…
  5. Robert Verish is a Gold Basin meteorite expert. He has published many articles on the finds made there. Here is an article where he 'puts it all together' and lets you know what you have found or what you could find in Gold Basin. There are more updates if you are interested in the area but this is a primer. I know I could say that I've found over a pound of meteorites from there over the years. http://meteorite-recovery.tripod.com/2008/aug08.htm Mitchel

  11. anyone know about any metal detecting books like about metal detectors or has metal detectors in it like treasure hunting
  12. Hi there, has anyone here used geophysical surveys to define a buried river chanel?
  13. Finally got to hunt an old home site yesterday evening. The elderly gentleman had given me permission to hunt all his property and he had kindly given me a little history of the different home site that were on the property. I listen intently to every word to obtain as much information as possible of each locations. One of the sites was a home assembled using wooden pegs. He proceeded to explain that he tore the home down and burned the balance then proceeded to get a dozer to grade the property and fill in with dirt. He did explain that anything there would be over a foot deep and he was correct, I couldn’t find anything that would date the property to the early 1800’s. The second site I hit yesterday and even though I didn’t find any nice relics I had a lot of fun just hunting. Moving around in the area I noticed a section where the Equinox would give many false high tones. Knowing this usually meant iron I opened up the screen and every sweep revealed multiply low tone iron signals. After a while I decided to start digging these low tones that gave an ID of -3 and found my answer, cut nails. Wow, that means I’m on an old site, yes, excitement overwhelmed me for a few minutes. Noticed the Ole man walking up the field to where I was I waited for his arrival. Knowing he would have more to say and the very first thing out of his mouth was, “have you dug any cut nails yet?” My answer, yes sir and handed him one and the story unfolds more detail of the site. He said when he was a child there was only a few foundation rocks left of this house, no wood but only the rock foundation. That was 80 years ago and he estimated the site may have been 200 years old. At that point I got extremely excited at what might be here until the very next statement from the gentleman. “Mark, I had the site leveled many years ago.” “But I pushed all the dirt to level the lot in one direction and I would guess your best bet of finding anything would be along the banks of the hill.” Well, yet another let down, a site dozed, that destroys the originality of where and what could have been found. But I’ll continue to hunt while I can and digging cuts nails is still fun. "Nails provide one of the best clues to help determine the age of historic buildings, especially those constructed during the nineteenth century, when nail-making technology advanced rapidly. Until the last decade of the 1700s and the early 1800s, hand-wrought nails typically fastened the sheathing and roof boards on building frames. These nails were made one by one by a blacksmith or nailor from square iron rod. After heating the rod in a forge, the nailor would hammer all four sides of the softened end to form a point. The pointed nail rod was reheated and cut off. Then the nail maker would insert the hot nail into a hole in a nail header or anvil and form a head with several glancing blows of the hammer. The most common shape was the rosehead; however, broad "butterfly" heads and narrow L-heads also were crafted. L-head nails were popular for finish work, trim boards, and flooring. Between the 1790s and the early 1800s, various machines were invented in the United States for making nails from bars of iron. The earliest machines sheared nails off the iron bar like a guillotine. The taper of the shank was produced by wiggling the bar from side to side with every stroke. These are known as type A cut nails. At first, the heads were typically made by hand as before, but soon separate mechanical nail heading machines were developed that pounded a head on the end of each nail. This type of nail was made until the 1820s. By the 1810s, however, a more effective design for a nail making machine was developed; it flipped the iron bar over after each stroke. With the cutter set at an angle, every nail was sheared off to a taper. With the resulting nails thus all oriented in the same direction, it became possible for the same machine to automatically grip each nail and form a head in a continuous mechanical operation. Nails made by this method are known as type B nails. Cutting the nails leaves a small burr along the edge as the metal is sheared. By carefully examining the edges for evidence of these burrs, it is possible to distinguish between the earlier type A nails and the later type B nails. Type A nails have burrs on the diagonally opposite edges, while the type B nails have both burrs on the same side because the metal was flipped for each stroke. This kind of evidence can be used to establish the approximate period of construction or alteration of a building. Type B cut nails continued to be the most common through most of the greater part of the nineteenth century. With the rapid development of the Bessemer process for producing inexpensive soft steel during the 1880s, however, the popularity of using iron for nail making quickly waned. By 1886, 10 percent of the nails produced in the United States were made of soft steel wire. Within six years, more steel-wire nails were being produced than iron-cut nails. By 1913, 90 percent were wire nails. Cut nails are still made today, however, with the type B method. These are commonly used for fastening hardwood flooring and for various other specialty uses."

  16. Steve has listed many valuable USGS books, publications and other items for you to obtain or find in a library so you can see where gold was found..This makes decisions so much easier about areas you might be interested in.. One bit of advice that I learned from these publications and I have had most of them for years for I studied the ones I was interested in carefully ... I soon realized these old time geologists that traveled to these sites many times on horseback is this, they were very thorough in their investigations... The language they used to describe what they saw made me realize this was the info I needed to successfully use a Detector in that area.. These words that you are looking for are Coarse, Shotty, Rough, Nuggety Heavy Etc..These are areas that contain gold that can easily be found by a persistent hunter.. Good Luck, Good Hunting and Never give up.....
  17. I was reading a news story today and was shocked at what they use for Chaff. Small bits of aluminum foil are sprayed out over a large area to confuse radar. The Australian military shot out a massive amount of chaff over Sydney to hide a training exercise from foreign Radar. I would be greatly annoyed if chaff was deployed over any area where I detect. If you checked the weather radars for Sydney yesterday you could have been forgiven for expecting a patch of heavy rain just north of the city. But if you poked your head out the window, it was nothing but blue skies. All that action on the radar picture above is chaff, Sydney had clear skies on the day of the exercise. What appeared to be an ominous storm cloud rolling across the weather radar was actually a military aircraft tactic used to hide activity and confuse the enemy. Known as chaff, it’s a radar countermeasure in which aircraft or other military targets spread a cloud of small, thin pieces of aluminium, metallised glass fibre or plastic. The radar-jamming material either appears as a cluster of targets on radar screens or overwhelms the screen with hundreds of returns, or “false echoes”. https://www.news.com.au/technology/innovation/military/it-looks-like-rain-but-its-actually-secret-military-exercises/news-story/0bd86fdc0b62ded8c5a32d04d96d78eb And you think canslaw is bad! ?
