Best Detector

My friend Geo
Thanks for ur reply.I'm looking for hunt gold or silver object(approximate 10*10cm size)like small
dish or rings in approximate 1m depth or a little more.pls guide me which
home made detector is the best for construct u think?
sorry for bad english
Thank u and goodluck

Best Detector

My Friend Geo
Thanks for Reply.I'm living in Iran.in here the soil is little mineralized
in more areas and some rough(mountain terrain).objects are very old
underground(relic).it will be great a detector could detect gold object 10*10
in over 1meter depth like Grave areas.i used ur good guides around DP and
construct one( not test yet).but DP has not sensetivity to Gold and
silver objects.
what is ur opinion?
thank u for it and goodluck
I have some good friend like u

pd3200 problem

i wrote a program for pd3200 working good but there are much parasite LF356 pin 6, can you help me ?

[ashkelon]

i think so nobody working with PD3200

[gurdal]

i think so nobody working with PD3200

could you uploada hex code here

[ashkelon]

i coud'nt attached the file here but there is hex file upside of the page, gave "erolunal"
thanks for your interest

HOW MUCH DEEPER CAN THIS MATTAL DETECTOR DETECTS A BURIED OBJECT OF 20CM SQUARE

coil resistance for pd3200

38cm, 400 microhenry and 0,5 ohm resistance coil has very sharp pulse shape, not moving first 150-200 microsecond, we must add a serial low resistance for coil.

Do you have any experience about this coil and resistance ?

Ashkelon, no need of serial resistance. The problem is in monocoil. You should use RX coil placed in induction balance. Here is the last circuit diagram of PD3200 before its commercialization in 2007. Added is Q6 - a MOSFET used as switch for power supply and a connector J15 for RX winding in induction balanced search head.

adress a new company pd3200 designer

hi makbg
i need web site (new pd3200 company)
Where did you find this circuit?
You can get a picture of the metal detector's Stinger( of course the metal detector)
I want to know the (pd 3200) is similar?
Sorry for bad English writing
Im from iran my language is persian
thanks

Hello, my dear friend, I plan to make a PD3200, so I ask you to send the circuit schematic and PCB Gerber files and HEX files to me, very grateful, and did you take deeper PI detector project, Iit is necessary, look forward to your help.Thank you and good luck

HEX file is only 'demo', that for free. it is without a discrimination.

I'm going to "have a go at this chip now I have my workshop up and running. Time is my enemy, in between my daughter and wife I have very little time to myself to research. I WISH they would understand that THIS is what makes the money we buy things with!

Hi,i would like to make a big square coil (120/120 cm.)for my pd3200.Can someone tell me what cable to use,and how many turns.
thanx
