The First VLF metal detector............

[Melbeta]

George Payne, who was working for Whites Electronics back then, began testing for frequencys in 1973. He came up with his design in 1974, and Whites went into model production in 1975. The unit was set at 1.782 KHz frequency. One of the units was given by Ken White Sr to Rocky LaGaye, who took it to Texas along the sea shores. Rocky found it TOO SENSITIVE, said it "even found the SMELL of iron"... Now I was a Whites dealer back then, so I got a copy of Rocky's test.
Here is that test...

Now George Payne, since I was a dealer, I got George Payne's document, which was inside the Whites magazine, and since it was very enlightening, I am going to put it right here... Sorry, something happened. I will try again... Ahhhh Heck, I give up, I could not stick it into this place....

Yep, I "enhanced both of these copies, for greater clarity", and both are very enlightening. Now up in the NW, Allan Cannon, had one of these Coinmaster V Supremes, he used his in old parks and old sites, and praised that machine immensely! He found old coin after old coins... But in 1976, Whites by then had so many complaints, because of its depth and sensivity, that Whites changed the frequency, from 1.782 KHz over to 6.592, and it was then more stable as far as its sensivity and depth. Whites also later on, in 1976, stuck in a TR discrimination circuit, and later on, they came out with a new coil in either 1977 or 1978. I got a 1976 Supreme with that new coil and with the revised TR discriminator in it... By then. Allan Cannon had sold his 1.782 KHz frequency Supreme, had the newer 6.592 unit, and said the depth was no longer in the machine and he was disappointed in the unit!

Well, I gave up, then posted, and dang if it did not go right into place then.... At least all three are in the posting earlier then this post!

Okay, first we had George Payne come in with the new VLF. Then whe got engineers, who introduced FILTERS. Now there was fast swing detectors, and slow swing detectors. What were they doing? Both were trying to FIX the problems with Phase Shift Technology Discrimination. Why? So their company could CAPTURE the SALES MARKET with their own fast or slow swing detectors. I have material, that goes each way. Going to begin posting so you decide.

First we will post Chief Engineer John Earle's discussion, of Vari-Filter technology. He explained it to us, and he also explained it to other engineers. But Compass Electronics was going through bad times, tottering, then they began to go out of business. So John Earle, went to work at Whites Electronics, and while he was still in command of his health, he came out with some great machines. He had some great machines at Compass Electronics as well, toward the end o that that company. What was Vari-Filter? It was a compromise using the Compass Scanner machines, to compromise between swinging the detector FAST or SLOW over the target! Here is John Earle explaining his Vari-Filter units... Now below, are two of Chief Engineer John Earls's files on filters, and a third file, by Monte, who also posted his explanation on the Vari-Filters... So now, after reading all three, you will understand all you want to know about filter technology...

Now I am still digging out of a hell of a snow storm, I got 14" of snow, entire all day yesterday, and it ended during the night. Now I am no spring chicken anymore. I learned to drive at age 9 years old driving an 1937 International farm truck, with stick shift, 2 speed rear axel, and with such a low speed, we called it Tractor Low, as I was born on my grandfathers farm during the Great Depression. I also learned to drive our two tractors that same year. We had no hired hand, and mom said you have to help, so I grew up quick and helped. Not bragging, just telling the truth here!

Now Monte, worked for Compass Electronics at first, was very knowlegable regarding electronics, has died the same as John Earle has also died, and left the earth. Now I do not know where either one went, neither one phoned me, nor did either one write or email me. I just know that they left and I still have what I got from them and saved it... Monte wrote about Phase Shift, not going to argue or defend it to anyone who does not want to believe anything I post. I used to argue with Monte, until I realized this guy (Monte) IS RIGHT. He never argued back you see... (Attachment is on Phase Shift) Phase Shift_s_vs5.0.pdf

Got to go out back now, and finish shoveling that 14" snow storm off of my lower patio cement. If not, it builds up, and then I cannot get rid of it until spring!!! After I get done, I rest you see, i do not want to have a heart attack...

[Melbeta]

Okay, finished earlier shoveling that large cement patio, and then since I have our youngest son coming here tonight, had to shovel the yard and shovel the driveway, and make a turn around place, as he is not going to come up driving into the yard.

So here I am today now, rested up a bit, enjoying an ice cold Dr Pepper, and am going to stick in another collection from MONTE! I wrote a bunch of pages, to Monte, as he asked me to do that, and emailed them to him. He answered each and every question that I asked. So here it is, a ONE OF A KIND technical document, full of questions, and full of the technical answers I wanted to read. Enjoy what I asked, and enjoy what MONTE said......

Here is where Monte explained what FILTERS do, and casually said that some filters, do affect the detectors ability "to see those targets"... Now that disturbed my thinking. I like to use my mind as the discriminator. I do not like a machine doing the discrimation for my mind! But discounting my feelings in regard to FILTERS, here is what Monte said in his explanation of FILTERS... I made some of his answers in BOLD TEXT!!!!!!!!!!!!!!!

I have another document to post, on the 1975 Whites Coinmaster V Supreme. Ken White SR, gave one to Rocky LaGaye, who took it down into Texas, to test it on the Texas Gulf Coast. He tested it, I got the TEST, Rocky found it TOO sensitive, with it running 1.782 KHz frequency. He said it even SMELLED the rust in the Gulf water. You see, the idea was to see if it would pick up the Spannish ships, that sank along the Texas shore line. So Ken White SR, along with many other complaints that it found too much iron, decided to change the frequency, from 1.782 to a higher frequency, and he did that change, he changed it in the 1976 model to 6.592 KHz frequency. He also made other changes to the 1976 model, he stuck in a TR DISCRIMINATOR circuit, making it run at VLF 6.592 KHz frequency, along with a TR Disc, running at the same 6.592 KHz frequency. It WAS A WINNER at that frequency! LATER it would have a newer better TR DISCRIMINATOR, which came out later and was still a TR DISCRIMINATOR. Eventually it would end up with a VLF MOTION DISCRIMINATOR circuit, but I do not recall what year that was right now..

Now it was NOT a PHASE SHIFT DISCRIMINATOR (PSD) circuit at these earlier TR Discriminators!!! The PSD would come because of the Compass Electronics Coin Magnum 1975 model which had a NEWER NO MOTION TR DISCRIMINATOR. There would be a battle between the Compass Coin Magnum and the Whites Coinmaster V Supreme, which dropped the TR DISCRIMINATOR, and stuck in MOTION DISCRIMINATION.

In the meantime, Charles Garrett, at Garrett Electronics had a built a newer machine, based on the Compass Coin Magnum, and liked it, but knew it still had problems SEEING IRON NAILS. Garrett had been testing the Compass Coin Magnum units, and been testing HIS OWN VERSION of the Compass Coin Magnum. How did Charles like the Coin Magnum? He liked it, but liked HIS OWN VERSION BETTER!!! He did not like it seeing very easy iron nails though. He wanted to test, experiment, and eventually figure out someway to get rid of the ease it had seeing iron nails!!! Read it and read Charles OWN WORDS!!!

Do I like the NO MOTION??? You bet I do!!! It finds silver dollars and finds gold coins very easy if they are in the ground under that COIN MAGNUM coil!!!!!!!!!!!!!!!!!!!!

Do I have Garrett's test??? You bet MELBETA has it too!!! I will stick it down there, right after the Whites Rocky LaGaye test! How do I have it??? I was a dealer with Garrett's, and also a dealer with Garrett's "brother in law", who had married Charles Garrett's SISTER!!! You see, Charles Garrett had sent his brother in law the results of Garrett's testing of the Compass Coin Magnum vs Garrett's own Coin Magnum!!! And now, you download it right after the Coinmaster V Supreme EVALUATION, and you get to read Charles Garrett's OWN WORDS!!!

I put it all in this forum, as I want Carl Moreland to have it as well!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Knowledge is power you see when one seeks knowledge...

But here is the Rocky LaGAYE test, I shall stick it right below. Now if you want to learn, you need to read and study everything I post, including each attachment...I do not put them into this forum just for the fun of it! MELBETA CM_V_Supreme_Evaluation_s_V5.0.pdf Garrett_NewsPaper Story_vs5.PDF

And here, it George Payne's 1974 CoinMaster V Supreme PATENT... Now it was for the 1.782 KHz version of course, metal detection only. MELBETA

Now the very first VLF, was the LOG MASTER unit, designed by George Payne for the LUMBER INDUSTRY!!!!!!!! IT was to find the IRON NAILS and SCREWS in the forest trees, so they would not damage the Chain Saws!!! Do I have that information MELBETA???? Yep! Melbeta even has that information on that UNKNOWN unit.......It is below... Can you enhance it so it is very clear and beautiful? YES! I just enhanced it before I posted it... But I have to tell you, only the logging industry bought them... Oh, I did the artwork on the Log Master as far as enhancement, so I have a copyright on that artwork!!! That copyright travels with the downloads of it too... But that copyright is good for this forum you see...

Oh, did Whites Electronics do a HIP MOUNT version???? Yes, they did a hip mount version. Very few were made and sold though, so they are a bit rare. Do you have a photo of the hip mount version Melbeta??? Yes I do. Ask and I will post 3 photos which I had stored in my folder. What about a Body Mount version Melbeta??? Well, they did it to mount either on the hip, or on the body (chest area), but theyMy only called it an HIP MOUNT version... Oh, this HIP MOUNT was not the Log Master unit, it was the CoinMaster V Supreme model you see. The Log Master came as the brochure shows it featured...

MELBETA, did White's Electronics ever make an detector that would find oil for oil well digging???

Funny you would ask that. Yes in 1938 Ken White Sr made what he called an OIL LIGHT. That was far before he made metal detectors you see. Photo??? YES, I got one photo in my files, and I will stick it below. Did it work? I never had one in my hands. So all I can say is "I think it worked". MELBETA

[moodz]

nice ..

[Melbeta]

nice ..

yes, it is very nice. Not sure what your oil light (your attachment file) is though. Can you explain???
MELBETA

[Carl-NC]

It's the owner's manual for the "Oil Light".

[Melbeta]

nice ..

Ahhhh! It was not Ivconic who posted it, it was you Moodz,n420479. So I have to apologize to you for not LINKING it to you Moodz. And I need to apologize to Ivconic, for thinking it was he who posted it. I suffer from Short Term Memory Loss, some things I can remember and can LINK them, other things I for some reason, do not and can not link them to whoever said or posted it. If Carl Moreland had not emailed me and told me, I would to this very moment not realize and not link it to whoever posted it. I read it, never had it before, all I had was the photo of the Oil Light detector unit. Thanks Moodz for giving it to me in this post. And sorry Ivconic, I thought it was you who posted it. I apologize to each of you guys. Thanks for it.

I seem to learn something each day, and the problem is to remember it! I got it now though!!!!!!!!!!

In 1975, when the Whites CoinMaster V Supreme detector came out, it was an ALL METAL unit, had no discrimination. But guys wanted discrimination, so Whites engineer began to build Discrimination "accessory" circuits to go with with the 1975 unit. It a kind of a TEST time back then, and I do have those circuits material in the directory. In 1976, it was the 200th Annivesary of AMERICA, so Ken White came out with an ANNIVERSARY unit. I got one, but mine has a newer discrimination in it, then the one they came out with in 1976, the fellow who was building the discrimination units back then was later the guy who build the Discrimination units for the Teknetics models. He was a friend of George Paynes, an engineer as well. I think he even followed George Payne into Discovery Electronics where George made some remarkable detectors.
