VLF

[mwaynebennett]

What is the advantage of Very Low Frequency machines? I see that Big Five Sporting Goods has a Famous Trails VLF machine for sale for $99 and it got me thinking about what a VLF machine might do. I know that the US military has buried large antennas in the ground so that submarines on the other side of the world could receive VLF radio communications right through the earth. So maybe VLF metal detectors probe deeper than non VLF machines. Is that the case???

I'm sorry but a $99 dollar metal detector will not get your anywhere. Those are not great units, even if they are VLF. If you want a decent starter's unit then go with something like the Ace 250, Tesoro Silver Umax or something like that. I think that what you are looking at is a very low end Bounty Hunter, I have never heard a good thing about that model. I do have a Pioneer 505 for sale. I want 175.00 for it, just came back from the factory, tuned up, new 8" coil, new button membrane, mind you it was only 4 month's old when I sent it in. I just wanted to send it in and get what ever done on it before I sold it. I out grew it to fast, I have many other machines that I like better, and they work better in my area and ground soil. Hope this helped a little.

BH1972:

I'm not in the market for a MD. I don't know where you got the idea that I am.

The add (see copy below) clearly states that it is a Famous Trails and not a Bounty Hunter. Where ever you got the idea it is a Bounty Hunter when I clearly stated in my original posting that it is a Famous Trails brand, I do not know.

You still did not answer my question about the advantages of a VLF MD.

Well talk about rude. But let me tell you K, Bounty Hunter MAKES THOSE, get it. You come in the bounty hunter fourm's, asking questions about metal detectors, and just assumed you were looking to buy one. but you know what let someone else help you i wont. The information is on the Internet, google it and find out yourself, or can you not do that?

BH1972:

It was not my intent to be rude. I have never seen any Famous Trails models listed in the Bounty Hunter product line-up. Do you have a link that shows "Famous Trails" as being part of the Bounty Hunter product line-up?

Are you in the market to buy a metal detector? I don't believe it is a given that everybody who visits this forum is in the market to buy a metal detector.

I asked a question about a specific MD technology and your response seems to be a marketing pitch to unload a metal detector you no longer want to own. If you were offended, please accept my apology.

It appears to me that Famous Trails HQ is in Anaheim, CA and First Texas's HQ is in El Paso, TX. I believe they are different companies and that you are mistaken.

Pretty much almost all MDing machines operate in the VLF frequency range 3-30 Khz. My Landstar operates about 6.6Khz. Some Mfg are higher some lower. In searching the web I found Minelab is using freq. near 50KHz and below 3Khz, Garrett around 7, XTL at 6, Fisher at 3,etc. VLF does penetrate better. Saying a machine uses VLF technology is more of a selling gimmic. They almost all use VLF.... Hope this helped..

I have an Elite 2200 which is the same as the Discovery 2200 I have been told. Nowhere in the owner's manual is the operating frequency mentioned. Do you know where I could find that info.? You seem to know the frequency's of various machines and want to know if you know if all the BHs operate at the same frequency since I believe all the coils are interchangeable.

Yea, that is 6.7Khz. It seems that BH operates around that freq.. I just googled the MD model and frequency to find out. On a side note being a FCC tech. MD units are probably typed accepted to operate only in the VLF freq band. Unless for special applications.

I believe most any hobby detector are either VLF or PI (Pulse Induction). I have not seen any ads for high frequency detectors other then ones for use in the food industry production environment. I have seen it said that the higher the frequency of a VLF, the better to detect gold, but it is still a VLF detector. Lower frequency may get more depth and sensitive to silver, but less sensitive to gold and nickel. High frequency more sensitive to gold, less depth, less sensitivity to silver.My understanding is PI detectors are more stable in mineralized soils found in gold bearing areas and for use in salt water. The down side is PI detectors have limited discrimination ability therefore not suited to trash laden sites.

I am no expert, this is just my take on what I have read here and there.

To answer the question, VLF technology will not get the same depth as Pulse Induction units. As a general rule PI units will get 2 to 3 times the depth as a standard VLF machine. While VLF technology has the benefit of decent discrimination. Hope this answers your question. regards Nugget.

LoL. I'm sorry BH1972...... I gave up a long time ago. Mark, your 2200 is a VLF detector!

Hey JJ:

Are there Very High Frequency machines? Are there Medium Frequency machines?
