Всем привет !!

WOOOW 23860 Unreaded Posts. Long time ago folks i had been here. I was needed to take a long time break !! Wink

So the Saga is continuing. Saga called CHANCE !! Andrey F. was moved on new site hosts so here are links to new sites and his new projects.

His new email

The newest one is Full Discrim Digital IB Metal detector with superior performance and excellent discrimination called "Квазар"  Kiss Quasar Metal Detector.   Kiss
................

There are also newest software updates for Chance - Version 1.0 to 1.21

Version 1.21 improved Guard Interval from 10....99

Version 1.20

Please Register or Login

http://fandy.hut2.ru/ChanceM_120.zip


      Изменения:

    Добавлена возможность регулировки защитного интервала от 10 до 50 (по умолчанию - 30).
    Изменены маски. I - железо слегка маскируется, II - железо сильно маскируется, при этом могут быть проблемы и с латунными целями, III - очень жёсткая маска, "отрезающая" пробки вместе с никелем.
    Убран режим подавления грунта, как не оправдавший себя. Предполагается, что изменяя Барьер и Защитный интервал, удастся свести влияние грунта к приемлемому значению.
    Мелкие исправления...

Andrey added possibility for adjusting Guard Interval from 10....50 (by default - 30).
Mask change mode. I  -Ferro slightly masking, II  -Ferro hard masking, with possible "jumping" over" brass coins, III - Very HARD Violent Masking "cutting" corks together with nickel coins.
Auto GEB removed like a mod which didn't justified himself. Andrey supposed with Barrier and Guard Interval control Ground influence can come to acceptable sense. Soft correction in code.
So folks from 1.20 there is full manual GEB. Everything depoend of your skills !!  Violent

Just listed for compatibility tests !! You can try if you want !!  Fight

Oscillograms for V1.21

Напряжение на катушке (точка X1.1, жёлтый луч) и форма тока через катушку (голубой луч). Общий вид. Для измерения тока последовательно с катушкой надо включить резистор 0,1 - 1 Ом, и смотреть напряжение на нём.

Voltage on coil (Check point X.1.1 yellow beam) and current waveform (blue beam). Common view. For Current measuring use in series with coil non-inductive resistor 0.1-1 Om and look at the voltage on them.

Original Chance coil L = 400 uH, R = 1,7 Om, Wire d = 0.8mm on acrylic-plastic framework d=4 mm. You can try lower Inductance value and use Litz wire for best performance. One of Treasure hunters gave excellent result 35 cm on 1 euro coin.

If there is much interest for Quasar i can open a new thread and give all important info for building and trimming this detector. So vote for new tipic here if you have real intention to build something new. I need minimum 10-20 interested treasure hunters and potentional builders. If no interest - well never mind - little job for me !! LOL !! Cool

Thats all for now. Good Luck at built and much bigger Luck at Treasure Hunting !! Detecting

When doing a big document always do it in word first that way you will not lose it. I have lost many posts for many reasons.

All the best

Sorry but i donít understand.
Are you telling us that we have to buy it from eBay as a complete kit?
Or are you selling it, and if so how much?

Hello
One question, it's better, use coaxial cable to connect the coil?
Thanks Luis

I'm not too sure that the twisted wire on the coil dose it much good.
