What md should I build next?

[Dean1971]

hello qiaozhi thank you
for your advice
i want to build krot but i think i will leave it until i have more experiance
i think im going build the tgsl
who is selling the kits?
ithink silverdog sells them do i need sepparet pcb for vdi mod
thank you
regards dean

The prices are the same between tgsl and the krot2.
The krot2 coil is much easyer to null. If this is yoour first vlf,
It will be easyer to make it work.

The kit is available here -> http://www.silverdog.co.uk/shop2/ind...&product_id=99
Silverdog doesn't supply PCBs or kits for the VDI option.
There's a 7-inch 5-pin widescan coil on eBay at the moment which is suitable for TGSL. BIN price is £50 with free postage. Plus it comes with a coil cover.
http://www.ebay.co.uk/itm/TESORO-7-I...4AAOSwOdpXzGaT
The same seller has a few similar coils for sale, including a couple of 11-inch widescans.

I would build TGSL first, then figure out how to build the VDI later. Once you know how to program a PIC to read the ADC inputs, and output to an LCD, the rest is fairly straightforward. The technique of target discrimination using phase demodulation is described in ITMD.

Hello qiaozhi
thank you
is pic programming same as doing a sketch on Arduino?
i thing I am going to buy the tgsl-edu
can I ask what the edu?
Thanks

Edu - means Eduardo1979, guy who redesigned pcb a little bit.

Hello cdi
thank you
i thought it might have something to do with the circuitry

Hi,
It's about the same. You can also programm PICs with ARDUINO if you have a UNO board waiting for job.
https://forum.arduino.cc/index.php?topic=92929.0

You can build a TGSL which has ONLY one tone. You can add a two tones mod. You can add VDI mod.
Or you can make KROT2 project which already has everything you dream of. But TGSL is a very nice project.

U can also make this Quasar Avr, which is DIP component and very similiar to Krot project.
Multi tone, feritte calibration, nulling coil without scope or multimeter cause there is ac voltmeter inside machine.
If u have problem to read Russian, i can post files for you.

Hi reptooyepi
thank you I do have 2 uno,s one has dip chip in the socket can I program it and remove it and use it for krot ?
and one has smt chip

hello cdi
thank you that's very kind of you
where can I buy the pcb or can I make the pcb?
been wanting to try etching pcb's
what coils can use?
what kHz ?
Krot? Tgsl? Quasar? which is best for iron infested soils because uk as a lot of iron minerals in soils?
Regards dean

i got one order on King Cobra... people are on Bara-Marauder-3 too... but i have slightly to change both... after that i will order batches... all winter project's orderers will get winter project before winter going...

I don't know about Krot or Quasar, but Tesoro detectors are well known for their ability to work in UK iron-infested soils, and are especially good at detecting small hammered silver coins.

only reminder. i have only direct output on Spectr author http://kusav.chat.ru/spektr_const.html

if you are not in course -

Clone PI=Koschej-5I/IM --- Andy_F vs Schedrin
Spectr=Koschej-18 --- Kusav vs Schedrin

I SAY AGAIN - AUTHOR OF KROT IS NOT ADEQUATE GUY AND VERY CLOSED FOR SOCITY. you can NOT get a help from him if you
will meet a problem.

I will post files later cause im not at home right now.
Well, for iron infested area's, there is no faster machine than Xp Deus, no doubt. But there is word about diy. For iron infested area, tgsl will be good, it has very good recovery speed and it is realy good in rejecting ancient rusty nail's.
