Need help from experts VDI connection

[beyonder]

Hi out there, I have a vdi unit that I bought it has a positive, a negative an X and a Y for connections. What I am trying to do is make an inline vdi attachment. The wire from the coil would enter the unit, then exit the unit and into the housing. The problem is this: How exactly can I connect it? I believe the X and Y are outputs but im just not too sure. I bought the unit online and I was able to power it up with batteries or the actual detector. I dont want to open the detector and void the warranty. Any help would be greatly appreciated. Thanks in advance

Sorry to say, but it will not work the way you want.
It would have to be connected to the X and R channel
on circuit board after the demodulators. Only a Minelab sovereign has the
the proper signals to the coil connector as far as I know.

Where did you get the vdi unit?

you could do a test on it outside of a detector.. to gaiin confidence in its ability ..

Power up and arrange 100mV on the X and Y inputs, you may see 45 as a display.

Thanx for your replies. Couldn't I demodulate the signal, attach the x and y then re-modulate it and send it back to the detector? Im trying to add this to a blisstool.

I've just read this thread which I found interesting as I also have a Blisstool V3 and intend fitting it with a meter, possibly one taken from a redundant Toltec 80. It has been done before and a video posted though that is no longer available. Really, we need two Blisstools, one to use and one to mess about and experiment with. With the newer versions coming out, it may be possible to get an old one a lot cheaper now on the second hand market. Connecting a multi-meter to the circuit should give an indication as to where a meter is best connected. Please post your findings if you get anywhere with this project and I'll do the same.
