Hi,
Ivconic whats up.
Have you cook something new lately?
I am happy to tell you that I have found my first small roman coin.Its cooper but I dont know from what ruler?
I will e-mail you soon some pic-s as we speek earlyer.
This happen before 2 days.In this snow!I were shore that I finaly found a coin when I heard the sweet honey sound.
This hill fortrres is like cheese holl to holl.But I get this neer one tree.Only 3 cm in soil but under the leaves +3-5cm.
With what did you clean your coins without damaging them?
Thanks
p.s.I see the D and N bn coin?Very strange.But I am almost shore that this one is copper.

Nice.
I do not "clean" coins. Usually i do put those in a hot water for hour or two. And that is all. If need some to clean than i ask one of my friends to clean those. He is expert and i am not. You better do not try to clean those but just keep as they are.Otherwise, you will risk to destroy possibly rare and expensive coin. As suggested, look in some catalogue or ask somebody who knows about coins.

Hi

Hi Ivconic!
How are you?Thanks for this tip!I will only wash my finds with wather.
What do you think about this scope please advice me!!
Can I null coil like your with this old model?
Because now with only multimeter at pin 7 of LF353,and I can reach around 150mV.
Device detect 10 euro cent coin at 25-27cm in air in disc mode!
What do you think can this TGS detect lets say a pottery full with coins at 60cm?Or this is inposible task?
Thanks
p.s.I will send you soon those pictures that I have promissed to your e-mail.I am having troubles lately.
But I think that this TGS is VERY good machine!!!
Yesterday I were able to detect in snow storm and the surfice were covered totaly with 20-40 cm snow.
Have you tryed to hunt in snow?
See you soon...............

Hi,
"What do you think can this TGS detect lets say a pottery full with coins at 60cm?Or this is inposible task?"

Now for you is POSSIBLE task, at least in medium soil.

Have a good time with it!

Kind regards,

Hi,

Hi,
I wish to all involved in TGS tread HAPPY NEW YEAR.
And wanna thank to Carl for this forum.This way our hobby is going further and further.........................
Only nice things in 2008.

p.s.Ivconic were are you?Havent post lately?

Hi Ivconic and all TGS fanatics.
Well i just whant to tell and share my expirencies and problems found with TGS coil.
My best coil it measures 4.8 mH and 5.7 mH, resistance btw 17 and 19 ohms respectively, for a 28 cms coil form, wire is 30awg or 0,25mm.
I measure the frequency and this reads 19.2 Khz
I tried another 28 cms coil, with 120 and 125 turns, resistance was around 34 ohms, and inductance was over 10 mH
Then my next coils were 28 cms form, 24.9 and 24.2 ohms, inductance 5.65 and 5.25 mH. Numbers of turns 90 and 95. This were the closest values i got, the frequency on the coil 15.1 Khz. Detection very poor.
Now i have more questions than before, cause i can get the correct deep results.
On this last coil i made, i measured inductance with ordinary multimeter, then i measured with a good inductance meter and this reads values around 8 and 8.9 mH. This also means to me that if i whant to get around correct values i should remove more turns, and this less than 90 and 95 turns.
So finally i belive that i must correct somo caps on the circuit.
I hope the experts on TGS can give me orientation on this, cause i m very confused now.
Ivconic, what inductance meter did you use?
120 turns give me more resistance than the one you posted.
I know i have errors here but can´t figure out what are those.
Regards and thanks for your support.

"...Ivconic this detector with 40cm coil is IB too and 6kHz I think,1000 steps earth filter,modern disc and ......... bla,bla,bla but have digg many ithems and a lot of coins...."

Actually...most important thing is LUCK ! And md operaters skill...of course!

Hi,

Hi,
Nelson.
I think that you use wrong data!
For DD 28cm TX=100 RX=105 w!

My TGS is working realy good now!I have found my first coin!And haven't even measure the working frequency!

I think that you should try nulling the coil from LF353 pin 7!
This way I finaly null my coil more than workable!/you null now using L2 end and start right?/

p.s.Happy new year

Hi,

Ivconic,
How did you conect two 10mF electrolitic capacitators to replace 4,7 mF Bipolars?
-++-?+--+?+-
+-?
Thanks
Because I cant find this here where I am located lately!

Try to get from 14 to 15Khz... better if from 14.4 to 14.8 Khz... if so and you null well the coil you go well depth with TGS.

Look also for optimum GEB setting ...otherwise you'll get many falses.

My TGS works so great now that I cannot post here about

People don't wanna belive me... think I'm a joker or something if I post.

Kind regards,
Max

HI TIKTAK.
WELL I HAVE 90 AND 95 TURNS, RESISTANCE 24,2 AND 24,9 OHMS
INDUCTANCE 5.25 AND 5.65 mH, FREQUENCY 15,1 KHZ
IF I MEASURED INDUCTANCE WITH MORE PROFESIONAL METER I GET 8.25 AND 8.65 mH. SO WHATS WRONG?
COULD BE THIS A PROBLEM WITH SOME TUNING CAPS ON PCB?
MY BEST COIL IS MESURING 4.24 AND 5.2 mH, RESISTANCE AROUND 18 OHMS, FREQUENCY 19.1 KHZ

Hi

Hi,
Nelson.
As I told you I never measure the frequency on my TGS.I just have experimentated a lot and with help from Max and Ivconic found the best nulling for me.
I think that the small diferances in some parts make a diferance,so every TGS is for itself no metter that we are using same elements.
So I sugest you try wind another DD with TX=100 and RX=105 and null afther firs OP!LF 353 pin 7.
Try.

[nelson]

Hi, i think i found my problem with coils for my TGS. I noticed that a 5 PF cap is on pcb, very close to RX stage. (See the drawing), btw pins 6 and 7 of LF353. But on the schematic there is a 10 PF cap. So can this change my RX frequency?
I m using a 5 PDF cap instead of the 10 PF cap show on the schematics.
Please give me a detail explanation, cause my best performance for TGS is on 19, 2 Khz.

Nelson

Hi,

Hi,
Nelson.
Unfortunatly I cant help you with detail exponation,you should ask Max or Ivconic for such.I am only entusisast!
But this 5pF cap is not your probleme!First this cap were 5pf and then the value were changed for better performance.But I havent notice any differance when changed this on my PCB.
I am afraid that your probleme is different.

Hi,
change about nothing... use one of the 2 values...

This isn't your problem.

Your coil is wrong if you get such higher frequency... as I told you before... maybe it's wire... or number of turns... or you made wrong tightening of wounds... leaving turns too open etc etc.

Also varnish tickness is important cause of the surface capacitance increase or decrease you can get.

I suggest you find sure 30AWG and made it again using provided data.

The bare wire will be exactly 0.25mm not other things (the varnished wire diameter goes from 0.27 to 0.28mm).

Wire is critical if you use Ivconics numbers on turns... so stay close as possible... otherwise you'll get another wrong coil.

Then nulling is most important phase in all this stuff... and require extra care... it's not easy thing... but you can do. Don't worry.

Kind regards,
Max
