RELIC HAWK

[tiktak]

Hi,

Hi,
From what I can see the windings should form 35cm circle innner d and 35,5 outher d!Which is cased in 37,5cm coil housing?Which have inner d=33cm?Because I cant find this size I will have to make a coil housing this days,so it can be readey for saling soon.And I am wondering what are the exact dimensions?
Also what is the shape of the overlap area?I remember that you have used minelab shape for this 27cmDDcoil for TGS.So it must be the same?But still think that we miss something there.
Finaly I will see this 37,5 cm coil.I am curies will it be deeper on my ruff terains?

Hi,

Max can you tell me whic IC which is?Please!
On this last schematic.

Hello Max and forum,
"do you think RH has a better electronics and balance, so will shine over TGS using same coil type/dimension" ?
I Agree with you 100% , perfectly ,
If the electronic schematic is better and good for the RHL , I will go ahead, search for the ic's number label??? and made the printed circuit , coil, etc... because here where i live in Mexico many mining soil , and the ground is worse very mineralized , we need vlf like Australian soil....
( I have a good home Pi for iron 100% !!!and very deep ), but now i need a good VLF to go deeper 1 meter or one meter and a half with discrimination for one feet square target...or less
Last week I test the TEJON (Tesoro) with his owner who know it for two years in our field test ...Do not detect target(copper 20X20cm) down deep to 80 cm in this mineralized soil ... and my doub was if Tejon is one last design from tesoro , I do not switch to Silver sabre to deceive myself...I have the Toltec 100 with original coil also it is same!!!...dn`t go deep...

perhaps like Ivconic say I must make a homemade coil for testing good (not tesoro coil because it is standard coil not very "tuned")

Also the same day we test the Minelab 3000 and 3500 for deep search with the big coil , the two react the same(no one better another) and go nicely to 1 meter deep for a 20X20cm copper target...
Thanks for this superb forum
...nobody sure have the time to experiment all the forum ideas ...
Saludos a todos.
Alexis.

Max preformulated all questions in one simple and correct question.
I also like to keep things as simple as possible.
Answer is YES, RH is superior over TGS in all points. YES i do beleive, RH with eventual 27cm coil will perform much better than TGS.
RH has more better optimized circuitry,more suitable working frequency for higher depths and more stabille&accurate discrimination.
Main advise would be; yes do make RH instead TGS, you'll get much better performances.
Only....problem so far was i didnt have all correct documentation for RH. TGS turns to be easier to make, fast and cute design, suitable for amateurs like us.
Now, RH "fragments" collected and maybe is time to give a try and make it.
Coil for it would be least problem. First need to resolve accurate schematic from all those versions, we have here.Last one looks more accurate.

"...and my doub was if Tejon is one last design from tesoro , I do not switch to Silver sabre to deceive myself...I have the Toltec 100 with original coil also it is same!!!...dn`t go deep..."

Most Tesoros not supposed to go deep. Those are not designed to go deep.
So it is normal.
Those machines are primary imagined and planed as excellent coinshooters.
I am more than satisfied with TGSL as coinshooter. Performs much better than 90% of coinshooters on market today.

RH on other hand, is designed as relic prospecting machine, so logically it goes very deep, no wonder.

Do not be confused here, those are quite different principles. Do not mix them and their performances.

Hola Ivconic,
Thank you very much for your clear response and sincerity,
First need to resolve accurate schematic from all those versions, we have here.Last one looks more accurate.
I agree with you , lot of headache if schematic i not accurate , if we can have a good schematic, it will be ideal ,and all the hard work will be concentrate in the realization of a good coil for the RHL.I will put all my work to try to help in this project of RH.
I understand also the big difference between coins research and relics ,and to not mix the case.... Here we are must interesting to go for relics or pots of coins... we have found already many coins all this years ... to want now concentrate in finding more "big things" !!! For you it is not the same with these beautifully Greek coins field where sometimes one coin represent a big artistic and monetary value.
Also we know the possibility and lacks of the PI design and for the moment forget to try to discriminate with it... waiting to see the real advance in the devil Nemesis project ???
Have a nice day of projects,
Saludos from Mexico

Hi,

Hi,
Ivconic.
I now that this is not the most important now but can you tell me what size is this coil finaly?I mean coil housing!Outher d=37 or 35cm?On the coil itself must be 35!/the windings/And finished coil 37cm!Right?

Ivconic,

Here is corrected schematic of Coinseeker2Pro. I traced PCB in your "post#27" & used schematic in "Amtech2005 post#16" in this thread as basis. It is 99% correct. Please check! Can you check component values? Do you have values for the 2 resistors connected to pin 3 of TL431?

[RufusGartz]

I make mistake in schematic.
New schematic & changes shown.

RELIC HAWK

HELLO, ON THE BOTTOM LEFT NEAR THE TL431, 2 RESISTOR VALUES ARE MISSING . DO NOT FORGET THAT A NEW CORRECT SCHEMATIC HAS BEEN POSTED AND IT IS COMPLETE. JUST NEED THE IC'S MARKED U-1 TO U-12 ETC............. THE NEW SCHEMATIC SHOULD CORRECT ALL PREVIOUS ERRORS. WE ARE ALL ON THE RIGHT TRACK THOUGH, EVERYBODY CONTRIBUTES HERE . THAT MAKES THIS FORUM SO GREAT!!!!!!! THANKS ,EUGENE

NEW SCHEMATIC HAS ERROR -

NE5534 in bottom right corner:
Output of op-amp is pin 6 on PCB not pin 1 as shown on schematic.

4053 - inputs for Z0 & Z1:
Pin 1 of TL082 connected to pin 3 of 4053. CORRECT
Pin 7 of TL082 connected to pin 5 of 4053. CORRECT
In that case for pin 3 & 5 = Z0 & Z1 mislabelled on IC or schematic needs redrawing to have pin 5 = Z0 & pin 3 = Z1. CONNECTIONS TO IC PIN NUMBERS ARE CORRECT.

Lots of pictures of Coinseeker 2 Pro PCB with & without components at:

When LM338 is substituted for TL431:
resistor from TL431 pin 3 to V+ is 10k
resistor from TL431 pin 3 to TL082 is 100k

I have no idea what values to use with a TL431.

DO NOT FORGET: This Coinseeker2Pro schematic is Bulgarian cutdown version of Relic Hawk.

[BGR]

this version has: VERY BIG REPONCE TIME, the discrimination is not working that good in ground, in air is FINE, GB is very good. Parts worth 15$ - good DIY device.

RELIC HAWK

THIS IS THE SCHEMATIC THAT I WILL BUILD FROM!!! I AM NOT GOING TO BUILD COINSEEKER-2 PRO BECAUSE TO MANY THINGS ARE MISSING !!! PEOPLE ARE COMPLAINING IT IS NOT GOOD COMPARED TO RELIC HAWK!!IT WOULD BE A BIG WASTE OF MY TIME . MAYBE THE COIN SEEKER 2-PRO WORKS GOOD IN EUROPEAN SOIL ,IT WILL NOT HELP ME OVER HERE . I NEED POWERFULL DEPTH WITH DISCRIMINATION. THE OLD SITES I GO TO, "THEY SAY ARE HUNTED OUT" OR "CLEANED OUT". BUT I KNOW THEY ARE NOT!! .................Eugene

[amtech2005]

RELIC HAWK

DOES ANYONE KNOW THE EXACT PART NUMBER OR ANY RESISTIVE MEASUREMENTS ON THE BLUE TRANSFORMER SHOWN . SCHEMATIC SHOWS A CENTER TAP. AND I ALSO DO NOT SEE A SECONDARY WINDING ON THE SCHEMATIC???SO IS THE PRIMARY WINDING USED AS A CHOKE OR LC FILTER ???? THANKS...................... EUGENE
