Pinpointer with tone discrimination Metaldetector

i want to say 2 or 3 things..

whos using Ferrite and have some problems.. not stable every rotation change buzzer is beep...

1- ferrite feel on the Earth's magnetic field ..
2- when the ferrite Standing on the table stable is well but when you change its destination ferrite will will be affected from magnetic ( physics rule )
3- easy way use little coil and thoroughly wrap with foil and use electrical tape and wrap again
4- use silicone ...required places with silicone ( housing )  

youll see work better than before ...

I had a stability problem  with just a plain coil, no ferrite. Discovered  that it was with the leads connecting to the coil. If I  put my hand near them, the buzzer would go off. Sometimes just moving place to place set it off. Coax shielded lead to coil fixed that. Still gets falsing tome to time. Going to try a small cap (.1uF or 100nF) across the reset switch.

	Thank you. I get the picture. However I am not going to join a Russian forum just to thank someone for his design. He can read it here. He is most welcome to join us. Dusty Carl Posted on: April 20, 2015, 03:01:59 pm Just found eddy71 in our member list. He joined, but has never posted anything. Nothing since 2014. Either he forgot he joined or doesn't want to talk to anyone, just download our ideas. Well now we have one of his. Dusty Carl

Just want to mention, I  am using a cell phone for most of my posting. No internet at home for laptop. Using phone as a hotspot costs me a lot of money with my provider. Not sure if you are aware or not, but there is no cut and paste on my phone. Will wait until I get to a wifi hotspot again so I  can use my laptop

A bad day at gold prospecting or metal detecting is better than a good day at work.

It will only be to my taste when I get to see it working in field, bench testing will remain bench testing.

At page 72 :

Addy sad ' important not to forget the 100nF on foot controller. Electrolyte to the board and I forgot to separate soldered point wiring. "  ( google translated )

and page 80 :

The better capacitors, the less false positives .. .. Checked ( google translated )
