PIM-2 Digital Metal Detector Project

[sparky]

My 12" coil is 2.2ohm and works great.
My 2mx2m coil is 2ohm (3 turns) and working great!

I'm thinking that the PIM2 isn't strong enough or has to be modified to drive the 50cm x 5m coil.

Thanks for all the help.

My large coil is actually 50cm x 5M. 3 turns with single wire as per PIM2 manufacturer. I did move the coil to another spot in the yard and now I get "connect coil" error. I made the coil with Telephone station wire which I believe is the same as cat5. (24ga, 8 cond. twisted pair)
I will make a 2mx2m square coil tomorrow and test it.

Hi sparky
What a test result for a small coil?
As for the large 2m x 2m coil high probability mis Specifications like In the number of tu,---,-----!

Important Note: You can make a test small coil and put any small metal beside him before the start on/off of the project will give the same message.
Read reply#93,#106,#108.

I did try that outside. The resistance is 2.7 ohms. Does that seem low? 3 turns of 24 gauge wire.
I will go back outside and try another spot in my yard. who knows, maybe I was over some gold bars.

Hi sparky
Testing must be out of the house because of the sensitivity - when give this message means that there is metal beside the coil.

Minimum and maximum resistance for coils

What is the minimum and maximum resistance for coils? My small coil works perfect but am getting "coil error" on my 2m x 2m.
Do I put a resistor in parallel between the two coil wires?

Hi volcano
R5=680 ohm 1W In parallel with COIL.
R16=2.2/5w The regular use Resistance or used.

Hi volcano
I make a Hardware pcb+ v05 only....but V06 more sensitivity lead to more depth+Less componentson pcb+ an unlimited time.

thank you jap
please give me the result of your test V5.
and I have a question ( some members talk about "dumper 680 ohm 1W " ) I don't know this resistor.

THANKS.
