The best metal detector coil that you can ever have for P.I metal detectors, unbeatable performance

[@Jennifer-007]

I LOVE my Sadie…… Good video Woody.

[@RedbackAviation]

Bunched coil NF 18 spoke Advantage, best coil I ever used, all size targets and true depth punching ability.

Very informative as usual Woody .

[@DetectorMods]

Thank you kindly

I was looking at frequency generator I bought a few yesrs ago never did anything with. It has b LL a 3-15 v input and two wire outout. .1%-100% and 0.1-150khz, i also have a bag full of mosfet breakout boards basically, its basically a relay using MOSFETs in place of s coil and contact. I was thinking about attempting a crude detector using it, using a send coil, and a receive coil, use a am radio if nothing else, set off station with the coil connected to the antenna but use an Arduino to sense the pulse current then listen to the sense coil, with the ability to pulse the coil to 150khz, in 1/10 hz increments, i was thinking of using snout 48 strands of 44 awg wire gor thr coil i think that is 0.01mm wire, its the smallest i can find, probably smaller than i can comfortably work with. I'd kinda like to attemp braiding it over to vinyl line about .1mm, its not to build a detector really . Its to experiment, the mosfets are good for 400 watts, each, pulsing a coil with 15plus amps. A coil with 0.2 dc ohm , maybe get a large high voltage capacitor and a high voltage dc boost converter, using the MOSFETs I have as a gate driver for a high voltage, high current IGBT, pulse the coil at 480v and instant current around 5-10 amps plus, using a higher resistance coil , possibly read the current ifvthr pulse a simply as using a shunt, with a micro controller, the the voltage to digital signal and such could come in handy , block the pulse then read the coil during the dead time. I would like to play around, see what i can learn. Maybe stuff that csn be readbinba book, that was learned 75 years ago, experiment and experience is thr fun of learning!

What about aerogel? Encapsulated in a very thin e-fiberglass as the former? I know there aerogel is fragile . shaping it then add a silk thin layer of fiberglass or even use wax, shape the wax coat in fiberglass, then melt the wax out, so its a hollow former, then the coil cover/housing. Possibly a medium infill 3d print. The possibilities are endless, and only a handful are possible to consider perfect! Have a awesome day!

I have a Vanquish 540 device. The company confirmed that it is the original, but I have a problem with the depth. Do you have any ideas for adjusting the depth and stability? Please.

[@DetectorMods]

I have never looked at one so I have no information on it.

[@janusstark4259]

How does it compares to the 8" from DETECH ?

[@DetectorMods]

I only have an elliptical from Detech, I do not use it. This coil is out being tested on a 6000, so I will be getting some feedback shortly.

Hello sir, I am from Egypt and we do not have graphite spray. Is it possible to grind the graphite column in the radio and add it to the liquid varnish and use it as a shield for a Surf metal detector?

[@DetectorMods]

It will not work but you can try the carbon from a battery.

[@WilliamKanavan]

Hi woody can the SDC 22x5 be reworked to suit Algoforce making it a 12x5 mono Cheers

[@WilliamKanavan]

12x5 not 22x5

[@DetectorMods]

All these detectors use a 300uh type coil, they are most likely interchangeable.

[@DanielSchweinert]

Great Info! Woody if I want to make my own 50" mono coil with this litz wire do I have to use the same 15 meters? Or how many turns and microHenry does the 50" have to be? Thank you very much for your videos!

[@DetectorMods]

Contact David via the Detectormods.com website as he has the info.

[@DanielSchweinert]

@@DetectorMods Thank you - will do it now!

[@frankgibbs5696]

Frankg Woody looking for a small coil for use with my SD2200D and also with my GP Extreme would you have a recommendation ?. or would a Sadie be OK

[@DetectorMods]

I would find a 8” mono or 10 x 5 sadie.

[@kamelkamel-qo6ch]

Woody thanks.

[@bunker_1284]

Hey mate, do you have any vids tearing down an NF evolution? I had pulled one down due to cut wire and was re joining inside the coil but forgot whether the stripped portion of the cable starts inside the ferrite choke or further back.

[@DetectorMods]

Ferrite choke?

[@bunker_1284]

@DetectorMods ferrite suppression sleeve might be the more correct term... this coil has the cable running throughout one where the main cable gets soldered to the winding wires and the smaller farraday coating wires. Now I'm not sure if the stripped portion of cable started inside it or further back

[@DetectorMods]

This is interesting as i incorporated a ferrite sleeve into coils going back 10 years or more, it is in one of my very old videos, i went away from ferrite to use a higher permeabilty iron powder type core as the coils are more susceptable to lower frequency interference from AM radio stations, as they are structurally air gapped you can use a very small core as they do not magnetically saturate. @@bunker_1284

[@bunker_1284]

@DetectorMods ok interesting... I can send you a photo if you like via email don't think you could tell the exact material though

[@sauddammam3389]

According to your experience,do large coils have an effect on health?

[@rodparker6530]

Yes, big nuggets are life changing.

[@metaldetectormilano6301]

how many uH for this coil?

[@DetectorMods]

It can be tailored for large and small pulses from 280 uh small gold to 340 uh for larger gold but 300 is a good .

[@stoop-tech1060]

Woody Woody thanks thanks 😢❤❤❤❤❤❤ fo🎉🎉🎉🎉 you make me very happy thanks alot .....you know i don't know how i thanks you ❤❤❤❤❤❤❤❤ i was have questions about that ...and still tell you are unik. ....i was need it

[@steveb9270]

Good content, the little sadi hardly ever comes of my 4500 .

[@DetectorMods]

Definitely a good Hoover.

[@scadstersworld5634]

Sir, I own a Fisher CZ6 with an 8 inch diameter coil and it has decent depth, but I would like to have a bigger coil so I could find things at deeper depth. I used to own a 10.5" coil and used it for relic hunting. I would like to have a bigger coil than that one. Do you know anyone who would build me a 14" or 15 " search coil to use on my Fisher CZ6 metal detector?

[@DetectorMods]

I do not know anyone that builds Fisher coils.

[@alexman1970]

Дорогой друг! Вы можете сделать большую катушку сам,это не так сложно как кажется, у нас в России многие делают,работы там немного,но самое долгое это ждать полимеризацию смолы, смола в катушке должна окончательно отлежаться почти месяц чтоб ее свойства были окончательно неизменны. Так же очень хорошие свойства катушки показала заливка катушки клеем kleyberit 501.
