Gold Master 66tr ... I Need Help With The Search Coil

[Murad]

Hello i have this artifact metal detector (66TR) from White electronics. but i need help with the search coil pinout diagram

i have 5 colored wires ( Gray = 12v , Black = GND , yellow , blue , brown ) can anyone help me determining what are those wires for excatly

if i had to make my own coil head because the old one is lost and i cant order another one online because my country restrict using metal detectors.

i'm newbie with such advanced detectors, but i'm sure i can make my own if someone guided me through this.

 

Thanks

Welcome to the forum!

If it was me I would try to find any newer used detector possible rather than work on a 50 year old relic. If that is not an option, I can’t help you personally with a wiring diagram. However, when it comes to that and making your own coils, etc. the absolute best source of information is the Geotech website and Geotech forum.

Thank you Steve

In general how i can detect the first coil 2 wires and the second one wires using a digital voltmeter. and where to connect the 12v line and the ground line. please any information would be useful for me

How i can tell the transmitter lines and the receiver lines ?

A 66 T R takes me back in time. That was the second detector I had from White’s. I gave it to a friend and he done a mod on the batteries to keep it going still.

what is the maximum range it detects Ridge ?

 

is it worth fixing it ?

I used to own a few of the old White's T/R detectors. In fact I still have one I keep around just for nostalgia sake. At over 40 years old they are long since obsolete technology. They can detect coin size objects at maybe 2-4 inches depending. They can't ground balance and so any mineralization at all really kills the depth. You can buy similar detectors here for $50 or less. The last couple I had were just given to me because they have no value unless in like new condition for people who collect old detectors. Surprisingly (to me) there are quite a few people who do that.

As far as identifying which wires are which - I just do not know. That is why I offered the Geotech links.

In it’s time it was a great detector but it’s history now. 

Just listen to Steve and you can’t go wrong.

Steve just posted a video on the MX 7 that would be a good detector for you if you want to dig more than tin foil all day long.
