IDX-PRO+VDI

Hi

I become PCB from Silverdog, realy higt quality and shipping was incredible fast.
Now I finished my PCB, coil I make like in Silverdog`s manual for DD coils. I just wanna be sure, that I understand correct coil connection to PCB. Is this right?

finish it and need to help

hi
i need help connection to the board.
my shield is ok??



the connection ok ?look the under pic ,please

Excellent for me the shield of your 2 reels must not touch.

no guru here!!!

any body here use lm7808 , becuse my battery near 11.9volt and dont work the detector(in datasheet write Vi=14volt)
correct?

hello, I need help.
I built two IDX and no work. PCB´s are from Silverdog. I tested the components and apparently are fine. I used the coils maxima 1500 from white's and the Spectrum XLT coil. I checked the supply voltage and correct. No sign of TX and the circuit makes sounds when my hand approached to the PCB. Both pcb have the same problem.

Can be the problem of the pcb?

ashert has wrote you -! ISOLATE ONE WINDING SHIELD FROM ANOTHER YOUR SHIELD IS SH-T.

Boards are fine built one and it works brilliant. There was a batch where one of the pads caused a short. post a high res picture of both sides of your finished boards would help. Do you have oscilloscope.

hi kt315
ok (i think your means)i remove foil and nuling one of the DD coil , correct ?

[kt315]

NO REMOVE FOIL -! only isolate, take a scotch tape and make.

Hi Kt315

I built a DD and did not put a resistor in the TX shield. Would that cause my coil to have a lot of chatter. Coil works fine sometimes and very deep but then it will become unstable. Another coil works fine.

Going to build another as it is also too heavy as well.

thanks a lot Mr kt315

insulate the shield of each coil with an insulating material such as tape eg to avoid the two touch screens.
