Filter for MFD

[Capt.Betances]

Hi all

I have a MFD that works good, but sometime it locate mineralization. I can identify if it is a rock with mineralization or some buried treasure using a metal detector. I need to know if there is in the market some filter to be attached in my MFD and save time locating mineralization.

Any help will be appreciate.

P.D.
I forgot to write. When I detect a very deep target, and my Eagle eye can't detect it, then, I have to dig and waste my time.

A common device that Bill Morgan (deceased) sold uses a 50k Ohm or 100k Ohm potentiometer wired between the two L-rods. Full resistance will pick up all targets. Decrease resistance to filter out smaller stuff. Or if you only use one rod you can attach one wire to the rod and hold the other wire in opposite hand. Other systems use a decreased voltage to filter out the small stuff. Like 135 millivolts.

Do you know about this filter sold in Europe?

Yep, I read the advertisement, and now I know what the manufacturer knows.

Looks like a fancy weight check unit to me....The same thing can be accomplished with a simple household dimmer switch with a small magnet attached to the green wire... Art

Vernon Rose designed an MFD "Weight Chek" that worked somewhat the same way. It cycled through the frequencies and there was some adjustment to eliminate the small stuff, probably a frequency shifter.

I agree with you. Electronically speaking, I think it is the same thing; a variable resistor controlling the frequencies.

A little note here about the device that Art talks about. Just so you know what he explains is different than what I saw and have. So if you build what he describes and it doesn't work, well that's because he didn't do a very good job of copying it. (My politically correct version).

Of course if you mental dowse then it doesn't matter how the device is built or what it actually does if anything.

Ok!!

Thank you Mike...If you try to mental dowse with one of these devices you will fail...Art

No need for a customer to be concerned with such details. When it comes to LRL's, they all do what the manufacturer designed them to do.

Since they all do what the manufacturer designed them to do, in the LRL industry you see very little in the way of comparisons between the products of different manufacturers. However, the Electroscope Gravitator ad is unusual in that it does admit that there are others, and then makes the claim that the Gravitator does the job the best. I don't know if that advertising claim is true but I certainly wouldn't argue with it.

C.B. I think it will work. An old MFD Weight Chek I mentioned is very similar. I guess it depends on just how much mineralization you have--too much and you will have to filter out the smaller gold, and it is possible that there are places the mineralization is more than that device can eliminate. But most places it should work. The old Weight Chek says it can eliminate around 5 kilos or so (15 pounds).

My weight check works perfectly! I'd shown how works my LRL in front people and they like to buy a LRL.

C.B., which device are you using for weight cancelling?
