METAL DETECTOR ADMIRAL TWO TONE - KIT - All you need to build powerful detector.
The Detector works on 8.4kHz frequency and has potentiometers for:
- Manual ground balance (GB)
- Discrimination
-Threshold (or Sensitivity)
-Volume
and switch for two tone & single tone with reject iron.
Also adjustable low battery indication.

Coil data - TX-1mH with wire 0.40 - 0.50mm, RX-7.65mH with wire 0.22-0.30mm but also can be higher. I recommend somewhere between 10-12mH for more deph

If you want to see how is work and how to build it you can check out my Youtube channel for more info - @HoBByTV_The_King_Detectors
 I have a lot videos about Admiral metal detector.

Notes: Some parts may be different depending on what is available in the store but will be the same value.
Тhanks for understanding!

Good luck with the projects colleagues!
