Magnacast 5000

magnacast 5000

Hi again; I was set on gold, but I was wide open on the other settings. I'm looking at the magnacast to bypass the wind BS that I have with hand held swingers. Sometimes I find OLD brass and very old iron( must have black electrolysis on it) when set on gold. I'm sure tweaking the settings will overcome this, but not the wind. Wind is also a problem out on the water.
Oh yes; Thank God for Art. He helped me a lot. I must not speak Australian, cause R/T was confusing as hell.
Some of my areas of interest, I have no idea of what is there, and I just want to see what I can find. In a historic area I was in, a man stopped to tell me that the local detector club used this park for staged hunts and training and that I would find very little. I thanked him, turned the disc. down and started. In 2 hrs. both pockets were FULL of coins and jewelry. Guess nobody had a tweaked Minelab. A LRL would have been useless there.
I want to break from the issue to say that this is one of the best forums I have been on. Hats off to the administrator !!!!! LT

In my years of locating, NOTHING compares to a signal line when it comes to discriminating. Even with an MFD/HID, if you just use the sweep technique instead of crossing/tracing the signal line, you are not getting the physical discrimination, just mental discrimination. That may or may not get you to the target. The signal line IS the discrimination. Yes, I own an Examiner and I don't use it any more, not even with an MFD. Not saying it can't work ,just that it is not that consistent. Even a signal line is not always going to be accurate. Sorry Hung, this thread is about the Magnacast. I repeat, please start a new thread.

I agree. What does an Examiner have to do with forward gauss? There are plenty of threads in this forum for Examiner posts. Take your pick and post there.
But, since when has anyone thought twice about hijacking threads at Geotech?
Maybe this is why it takes a few hours to track down the fragments of information about any particular topic in Remote Sensing forum.

Getting back to the Magnacast 5000, a new thought is emerging that helps to explain LRL theory in general. From what I gather in Mike(Mont)'s last few posts, the signal generator in the Magnacast 5000 as well other Vernell Electronics signal generators do not discriminate metals or broadcast RF for any measurable distance. In theory, the small square wave signal is so weak it is barely detectable unless there is some metal that also has some very weak mechanical (molecular level) vibration with electrical artifacts. As the theory goes, the weak electronic square wave signal and weaker electronic artifacts from the metal are both undetectable alone when using ordinary electronic receivers. But when a piece of metal has minute electronic artifacts oscillating at the same frequency or a harmonic in near proximity of a signal generator (near = defined as a few inches to a few miles), a line in the air between the metal and signal generator becomes more detectable above the general electronic noise in the air. Thus, the term "signal line". So the theory is a small signal becomes more detectable above the noise levels when moving a detector along this line between the signal generator and metal. At least this is the theory I gather from what I read.

But this theory opens some questions:
1. According to Mike(Mont), the signal generator does not perform any metal discriminating. This is done biologically through human sensory and mental methods.
However, we see there are adjustments on the Vernell signal generators to select which kind of metal the signal generator is searching for.
Why does this adjustment exist if the electronic equipment does not physically discriminate metals?

2. We see a possible explanation to how the term "signal line" evolved. But is there any information that could explain what "forward gauss" is?
Can it be explained if we reject the Maxwell heaviside equations, or is it easily explained by conventional electronic theory?
Maybe it means the detection is done only on the forward side of the antenna, not the rear where the signal generator gets in the way...

3. From what we see in the Vernell Electronics locators that were studied and dissected by electronic engineers, they operate at VLF/ELF frequencies. Mike(Mont) thinks the Magnacast 5000 operates around 400 MHz, but can't be sure because his frequency counter does not go that high. A suggestion for Mike(Mont) is to connect a test probe between the antenna and ground, and check for frequencies between 10 and 10,000 Hz while switching through the 6 frequency adjustments on the Magnacast 5000. From what we know about the Vernell designs, this is where the frequency is likely to be found.

I think the term forward gauss came about from the info that came out in 1990 from Larry Williams of Treasure hunter mag. He put out a report that said the mfd will develop a heart shaped field with the ground probe 30 ft behind the machine and the pos. probe in front. A lot of good info in those 19 pages. LT

Early on Larry was fascinated with LRLs, but as time went on and no one could ever locate his big pile of buried silver, he became more and more skeptical about them. By the time he gave up THC, he had pretty much dismissed LRLs as a bunch of nonsense. Of course, Steve Ryland, who took over THC from Larry, was a geophysicist and dismissed LRLs from the start.

[Mike(Mont)]

Carl has a VR2000. He has electronic measuring equipment and a lot more knowledge about using it than I do. My instructions say to not touch the outputs as it is dangerous. It said do not connect or disconnect with power on. Wait ten minutes. I guess I am curious what info he measures.

When I was doing research with MFDs and LRL about 15 years ago I was skeptical of any signal lines. I had a friend of mine who could see energies on higher levels (a true clairvoyant as I had tested person extensively) observe on the higher planes any energies when I turned on the MFD. The friend could see a fuzzy white light energy line from the transmitter to a metal target. When I walked through the line with or without the dowsing rods the line would get broken and it took at least a minute for the line to re-establish. I could sense the line but not see it. The MFD would transmit to various metals depending on the frequency. Another discovery was that when the sun came up much more than 9 am the energies from the sun would dissolve the energy lines. Later in the afternoon the sun would get low enough on the horizon for the line phenomena to work. Lots of this type of discoveries coincided with old downing books like Abby Mermet.

...Be careful with what you say here, otherwise you may cause a serious short circuit in Carl&gang's neurons.

[Mike(Mont)]

Here's a technique I use. As I said, I point the scan gun at the ground and walk in an arc in front of the transmitter antenna about 13.5 feet away (radius). Now when I get directly in front of the antenna the tone and clicking will be the loudest, so I look for any variance. In other words, if the tone starts to decrease instead of the usual increase I check it out. So when I am pointing the scan gun at the ground the handle is in the horizontal position. I twist it back and forth like turning a key in a lock. I watch the meter and normally when there is a tone the meter will stay up high, or no tone the meter stays low, but right near the signal line the meter will deflect almost the full scale with each twist of the scan gun back and forth. I don't know how well this will work with the VR2000 because the receiver antenna is quite a bit larger and not too easy to twist quickly. I don't twist it all that much, probably less than forty-five degrees each direction (towards the transmitter and towards the target area).

Signal lines are just a trick of the mind.
Try re-reading your posts quoted above. It's just a load of pseudo-babble.

Is this from personal experience?

Hey Mike, nice try in your temptative to start a discussion over elevated matters, but as you see... even after years, some 'patients' still get disturbed.
Better try somewhere else... This place is doomed in ignorance.

Translation:
Better to spread pseudo-scientific nonsense, concerning signal lines and dowsing paraphernalia, on other forums than to waste time here where BS is not tolerated.

Hi hung

you are more and more Gauss forwarded. This can lead to total circular polarisation of brain wave.
