Схему и Гербер файл платы выложил на форуме. Страница 38.Софт выложу позже.

The scheme and Gerber file of the board posted on the forum. Page 38. I'll post the software later.

It means "shield".

= Screen / shield

Now it's clear, cable shield.

I expect it to be more vulnerable to coil imbalance than other detectors of this kind. Rx gain is critically high.
Also the Tx PA is vulnerable to cross conduction (with both MOSFETS conducting at the same time) regardless of the resistors and diodes on the gate side. Easy fix would be placing a drain resistor in each drain instead of a common 10 ohm resistor.
Otherwise it is a simple clean design.

Новое ! New !

Два АЦП это сила ! Two ADCs are power
5 копеек СССР 30-32 см в грунте. 5 kopecks of the USSR 30-32 cm in the ground.

Квант БТ. Первые тесты. KVANТ BT. The first tests.

5 копеек 1981. СССР
Металл: медно-цинковый сплав
Масса: 5 г
Диаметр: 25 мм
Толщина: 1,5 мм

5 kopecks 1981. USSR
Metal: Copper-zinc alloy
Weight: 5 g
Diameter: 25 mm
Thickness: 1.5mm

Позже на тестовой ямке сравню. На Апексе частоту 15 кГц поставлю. Катушки считай одинаковые у Кванта Фи=250мм, у Гаррета 280х220. Думаю Апекс все же выиграет. Если проиграет дедушке Гаррету придется всех своих инженеров уволить!

I'll compare it later on the test pit. I will put a frequency of 15 kHz on the Apex. The coils are considered the same for Quanе D=250мм, and Garrett 280x220. I think Apex will still win. If he loses, Grandpa Garrett will have to fire all his engineers!

Продолжение следует..To be continued..

Buenas tardes!! Thank you very much for sharing this new project!! What is the last skit? Could you give the data for the construction of homemade coils? I wonder if it will work with the 11 inch SIMPLEX coil?
