Would a 2.5 m coil frame work?

[AmmarFoggara]

Hi,
The largest one in the famous table for PI coils is 1.8 m with seven turns. I wonder if 2.5 with 5 turns would work. Perhaps, it's too large and impractical. But I don't care. I want the extra depth. The cache we're looking for usually here are way too deep. We should be working with gpr but we can't afford one. Has anyone tried such large coil before? What does science say about such big frames?

Any help would be much appreciated.

Even if it did work, it would be impractical to assemble, carry and more around with it, unless you have at least 2 people to carry the coil and you carry the MD unit.

It would be easier to buy a metal detector that detects voids, most probably you're looking for an entrance of a tunnel/cave at that depth.
Besides the Ottoman empire, I don't know of other people digging that deep in soil to bury valuables. Even then, they dag at 3.3-3.5m which you could locate easily wth a 1.5m coil.

If the cache is not completely made out of metal, I don't think it would be easy to locate it with such a big coil because of the small amount of metal relatively to the target size.

Sure, you can make the coil that big. What detector do you plan to use?

Hi,

a 2x2 meter coil is no problem see picture. A 2,5x2,5 or 3x3 meter coil should be also no problem. You only need a stable frame works.

They used this big frame for search in Mexico desert ,meteorites ! can cover large surface area quickly....

Thank you for all the responses. Sorry I didn't respond quicker. I was in a remote area without coverage.

I don't mind the impracticality. I'm just worried about other aspects.

What kind of detector are you talking about, please?

Besides the Ottoman empire, I don't know of other people digging that deep in soil to bury valuables.

We are talking about underground chambers. We had people finding a chamber beneath a chamber and they suspect a third one to be beneath but they couldn't find the entrance. And it's Roman. We understand that kind of targets needs GPR but it's just too expensive here. They're being sold for x7 of it's actual price here.

Sure, you can make the coil that big. What detector do you plan to use?

A modified felezjo. It's pretty good and can detect void too.

You only need a stable frame works.

Thanks for the tip. Now that you mentioned it, it's gonna be a bit challenging for such large frame. I wonder if pvc tubes would cut it.

Yeah, what I've read so far is that people use big frame to cover more ground much quicker. But I can't fully understand why it's not favored for its effective depth. Made me wonder if I'm wrong about this somehow. I can't be smarter than all the PI users that came before me. Maybe you guys just never hunt for such deep caches?

If you found the second chamber there's a high probability that there is no other chamber, unless it is very well hidden and sealed with horasan, in which case the only real test would be with vinegar and hammer taps on the walls and the floor.

The only machine I've tested in voids is White's TM-808 but I'm sure other similar detectors would do the trick. More experienced users will give a better answer on this topic.

I didn't find the chambers. Others did. I was just giving an example of the kind of targets I'm aiming for with 2.5 m frame. Would it work? Felejzoo manual says 2m can give 8m depth. Could 2.5 give 10m?

Hello
Can you give me the felezjoo manual?

[MDfanatic]

I can't find a reason why it wouldn't work, all you need is 5 turns with 0.85mm wire. You can wrap the coil with tape so it can be flexible and you can construct the frame with PVC tubes and assemble it on the spot.

But even if you did find a target so deep, you would have to find the entrance anyway, unless you want to dig through hard soil and rocks

These are both the original man in Persian and the one I got after using google translator to turn it into English (With some manual editing). Hope it's helpful.

That's how we roll

Thank you for your kindness
How about Your Felezjoo pi stability ?

You're welcome. Mine is pretty stable. The one who made it said the felezjoo on the internet is very unstable. He claims to make some modification on the original version. I can't tell what he did but his version is certainly stable. But I never used one that was made exactly like Hamid's original schematics.

doing more much frame you lose out the depth to small targets. you can NOT deceive physics rules.
