CCO Metal Detector
This is the CCO metal detector in operation, I'm using the republished modified circuit which uses a 4069 hex inverter and a TL071 to replace the AM radio in the original circuit.The coils are not the full 50 turns and made from the wrong gauge of wire also, they have yet to be mounted properly on something. The sensitivity of the circuit is too high, touching any parts or wires will cause random chaotic frequency shifts, even shielding the wires doesn't work since the main problem here is induction and not em waves. When complete, all parts of the circuit will have to be made rock solid so that they can't move relative to one another, other wise using the detector will be impossible.The pcb was made by grinding away the copper foil with a dremel and a small broken drill bit. Crude, but it works.
World War II Metal Detecting - Luftwaffe MG15 Machine Gun and Hitlerjugend Relic Hunting (HD)
Fresh video with the recent relics from Team WWIIMD. Last february we visited the former airfields of the German Luftwaffe in world war two. In the search for war relics we discovered some amazing finds that we will share in our new battlefield research video. Such as medals, awards, fighter plane parts and even a MG15 machine gun! We also found equipment pieces and other interesting things that were left behind in the woods after the war. Feel free to leave a comment. Greetings from Holland!

Simple BFO Metal Detector
eBay link (schematics included): http://www.ebay.com/itm/251484583990?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 This is an extremely simple BFO style metal detector demonstration using two basic coil / inductor oscillators running at about 430kHz producing an audible beat frequency in the presence of metal objects. How it works: This particular arrangement "looks" like a typical Double D style coil arrangement, but don't let it fool you. A "DD" has one drive coil and one receive coil. In this case both coils are being driven. When two coils that are driven share the same plane they will mutually oscillate and seek the same frequency. The magic happens when the coils overlap slightly. When they overlap at a certain point there is a balance where the mutual oscillation goes away and they don't influence each other, allowing them to freely oscillate and become easily altered by their environment ... i.e. a metal object. The Idea is to place the two coils in this overlapping arrangement so that they are JUST on the edge of influencing each other at the same oscillation, but are very susceptible to being altered externally. This type of detector has a slight advantage over a standard BFO in that "both" coils are near the sense field which help to minimize any ground effects you might otherwise have using a single coil near the sense field. Ground effects are caused by soil variations, such as mineral content, moisture, etc. Since both coils experience virtually the same ground conditions (unless passing over a metallic object), ground effects are mathematically canceled out leaving you with a higher signal to noise ratio when detecting.
World War II Metal Detecting - A Weapon Treasure - Eastern Front Relic Hunting Episode 9 HD
Episode IX: This is a video of our last tour this year. It's not really a tour like the other ones we've been on, this one was just a one-day-tour actually. But even though it was a short tour, it was our best tour ever. We found a weapon dump pit with a total of 6 weapons in it, plus a lot of magazines in really amazing condition. We found the long awaited MP40, plus 4 Degtyaryova Tankovy (DT) machine guns, which are quite rare relics to be found with a metal detector.. It was really a find of a lifetime and we invite you to take the tour together with us in this video. Our advice: don't skip the video, just sit back and enjoy :) Feel free to post comments or ask questions. Enjoy the video! *Updated video* This video is an update of the original one, posted in December last year. The old one had some flaws in it, but it will stay online for now, this version serves as an enriched second part/update. We added some updated information about some of the finds and also more information about the location where everything was found. We have received a more than average amount of questions about the location, so we decided to give a bit more information. We still don't reveal the real location, something you'll understand. However, we explain in this video (with the use of a map) what happened at the location during the war, and why we found all these dumped weapons. Note: this is the last reupload for now, the next video will be a brand new one! Stay tuned :) A hunt with Boddeus and Lean, visit his Boddeus' relichunting channel https://www.youtube.com/user/boddeus and Lean's channel https://www.youtube.com/user/emmuh0uttt Note: I do not own the music used in the video, nor will I make money with it!

Cache of coins found while metal detecting- LIVE!
Added: We do acknowlege that the use of a knife was a very bad idea. Mike thought it was some sort of plate and called me once he brushed away the dirt to film it's removal. The overwhelming excitement of realizing it was a container and anticipatation of what might be in it took away any calm sensibility.And for those asking, it was found with a Tesoro Cibola. Thanks! While metal detecting during the Grand National Relic Shootout sponsored by The Treasure Depot, Mike uncovers a cache of coins in the area of a Civil War camp among artillery frags and shells.

World War II Metal Detecting - Eastern Front Relic Hunting Episode 8 HD
Metaldetecting WW2 Episode 8. Hello friends! This is already tour no. 8 to the Eastern Front, time really flies :). In this 2-day-tour from October this year, we found several interesting relics, including several weapons (Mosin Nagant rifle and carbine, K98k) magazines (Stg44, MP40, MG42), a WWI model M18 Stahlhelm, canteens and other cool relics. We visited multiple locations, so all this stuff was not found in just one place. The locations we visited are not well known to most people, a thing that makes them much more interesting and, as you can see, offers a lot to discover. As always, we don't sell any relics, we only dig them up to save them so that they are preserved for the future. Our finds end up in some private collections, but they will be displayed together in the future (in public), rather soon that later :) Feel free to post comments or ask questions. Enjoy the video!
