Fisher 1266 Part 1

Too bad it was not Stainless Steel !!! How old , Before world war II ?? How deep in the ground ?? Amazing , That's something more like from China or Japan , not U.S.S.R ?? May I ask what machine you used , P.I. or VLF ??...................Eugene

Hi Sean Goddard

Fisher 1266 Part 1

KT315 , I just checked some history and Russian Sword's and Sabre's go back to the MID 19th century and from looking at the rust , maybe they are very old !!!! Wow, Are those worth anything ???? ..........Thanks .....Eugene

I repeat ALL INFO ON COIL HAD BEEN IN FORUM! ... and I say nothing new now

simply get it and enjoy!

Hi KT315

I saw that pages latter, but I don’t remember where I saw them.
With those pages, was another circuit diagram.
Are you having them complete? Can you upload it completely?
Do you know circuit model?
Regards.

There exists wonderful Chinese metal detector called the MD3030. I import huge numbers of these into the UK and sell them to hobby shops, outdoor pursuits, and garden centres.

Now, this machine IS a 1266 clone, soooooooooo the search head will work fine, and the BEST bit is they are VERY well made resin cast well balanced, open webcoil and they only cost $50 each!! I can get a whole load of them if people want them but you will have to change the connector your self, Or use the same one on your own Fisher clone .

I would have to have around 30 requests to make it worth an order "out of season", but if enough people here want these heads, I am happy to buy a load for the forum.

KT315, I have that somewhere too, originally from the UK repair centre (the OLD one). It's amazing what you can get with a little spare change

T101 is a STANDARD centre tapped AUDIO output txfr. The sort you find in cheap transistor radios. All you ae loooking for is the 180 degree phase shift.

I agree those are very cheap and presents excellent starting machine. I had 2 devices so far and sold them out also.
But first i perormed detailed checks.
Looks like some of Fisher's previous models, but i am not sure it is 1266 clone.
Many things done different than on 1266.
One thing really bugs me on MD3030 is huge unstabillity. I tried somehow to correct that problem, yet without succes.
My last doubts are in coil. Although very fine,hi quality...seems coil is not that good inside. Something is missing there. Performs like without faraday cage or not nulled well? Not sure.
When Sense is high MD3030 is "feeling" to much grass,hotrocks and minerals. Bedlam of false signals. Yet if Sense is lowered to stabilize it, than depths are low, very low...turns to very shallow detector.
Not the case with original 1266. At original 1266 operater can always notice huge difference between good signal and false by such different audio. At MD3030 audio is same on good signals and falses, no difference.
Pitty. Device itself is produced very quality. All looks excellent. Enclosure,shaft,coil especially....it is very cheap..shame.
So..Sean i am very interested in you reasons to beleive it is actually 1266 clone?
Best regards!

I keep these too. but I do not keep all comments following the schematics and certainly can say nothing about it was released or not. it was a clone of 1266 I believe.
happy hunting

Hi KT315
Thank you, yes this is my intention. I had that file completely
But I can not found It on my cd’s .
Are you know any body built it?
Or anybody built it?
Best regards.

[kt315]

Hi KT315
Thanks for all. Yes, some parts of circuit seem as fisher 1266x.
Best regards.

Hi KT315
Please see 1266x clone circuit, on the pot. Wrote “npar”.
what in meaning of “npar”?
Best regards.

Hi KT315

seems like Bulgarian but maybe Serbian. I think PRAG means POROG in Russian then it would be THRESHOLD.

Hi
Maybe you know about russian Metaldetektor AKA model BEKTOP,its with LCD screen. Did you try and test this MD?
