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.

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.

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.

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.

      I'm new to nugget shooting and have recently got a Gold Monster a couple weeks ago.  I wanted to get a little time on the machine and there's snow on the claim I have access to so I took the machine out to some nearby dredge piles to play around.  I got about 8 hrs on the machine so far. These dredge piles are about 15' high and I quickly found out how dangerous climbing around steep, frozen big boulders was....lol  I did get a few "hits" on the GM on top the piles but after carefully removing rocks one at a time I realized whatever set the machine off kept falling down in between the rocks deeper into the pile the more I chased it?  Very little small gravel/soil type material....just big cleaned rock.  So I learned that hunting the tops of these piles will most likely end in defeat or injury.  I hunted just a few hrs on the wooded flats near the base of some piles.  So far I've dug lead bullets, casings, some iron, and new aluminum so the machine is working, etc.  My question may sound stupid but I'll throw it out there.....   Is there a semi productive way to search these piles?  Should a guy just search around the bottoms and flatter ground where maybe some of the finer material has finally settled?  I'd taken a rake along with me when I went but never really used it as the rocks in the piles were much bigger once I got up close....lol
      PS.....Having only driven by these piles for years I must say that once I actually crawled around on the piles I was VERY impressed how much material those old dredges dug outta that creek.....amazing to say the least..........
       
      Thanks

      It has been a while since we last heard from Klunker on this forum. I sure miss hearing his insights on detecting and his other commentary. I don't know if he is just too darned busy detecting and finding gold? Or his computer broke? Or if he has been banished from the forum from the powers above . Any which way, I sure miss his 2 cents worth. Please come back!

      To start with need good MD to take with me so please give me your advice on the very best gold nugget detectors for the budget of $800 or less?
      What are the very best gold nugget detectors for the budget of $800 or less? Even these Chinese made MDs if you think they can do the job comparatively then please list them all. 
      Thank you.
