Fisher 1200 series coils not what we all thought

[MarkCZ]

This weekend me an my older brother ran into something interesting but at the same time troubling events.
He has had a,
1265,
1266, and now owns the
1270,
And I have at present a 1266

Now he had recently gotten a couple of 1200 series coils. These coils were in excellent condition but they had the older style smaller gray cables, like what was used on the 1265.
Here is the problem, he got them with the understanding that all the 1200 coils interchange with most models except for the 1220 and the 1260.

So, he mounts these up on the 1270 and well they somewhat work, but they were in no way RIGHT! so he comes over to test them on my 1266 and both of them were fine and operated as they should.
So, I slide the connector housing back on one of older coils and on one of my 1266 coils and the wiring is different, the older coils had a green wire not found in the 1266 coil and the center #5 was used on the older coils but omitted on the 1266 coils?

Here is the strange thing about all this,
Those older coils (I believe to be 1265 coils) worked fine on my 1266, my 1266 coils worked great on Ron's 1270, but the 1265 coils didn't work correctly on the 1270. Not correctly I mean in air test they only had like half the depth and the unit was way to noisy.

What Ron nor I could understand is how can the 1266 coil work great on the 1270,
How can the 1265 coils work great on the 1266,
But the 1265 coils so poorly on the 1270?

Its like the 1270 is backwards compatible to the 1266, the 1266 is backwards compatible to the 1265 and so most just thought that all these coils would interchange with all these models. After this weekend I would have to say that just isn't true! I would caution anyone with a 1270 that if your looking for some coils on the used market that those older ones with the smaller gray cables may give you very poor results. Now, owners of the 1266 will probably find the older coils to be fine.

Strange if I may say so myself.

One has 4 wires and the other had 5 wires, went thru this with my 10.5 coil that wouldn't pin on the 1270 but worked on the 1265X, just fine. Fisher wanted to know the manufacture date of the coil because they made a change in the wiring and certain coil "WERE NOT " compatable as the ads said. I'll try my 1265X stock coil on my 1270 and see if it's ok, but I think I did that for Ron once before.

The connection or should I say the connectors were all the same, the newer coils just didn't have a wire connected to #5 pin (the center pin)

The newer 1266 coils really only has two wires and a braided shield for each one, two wires, two shields. The 1265 had more colored wires and the # 5 pin was wired.

I'm not sure of when the wiring change but I know that my 1266 is a VERY early model because it has the white 8" spider coil and has two circuit boards which they only did for a short period of time until they could condense the circuits into one board. And my coils has the larger black cables and the omitted pin #5

As Mark and I were testing one of us started talking about my 5x10 elliptical box type coil, why does it work? Well I didn't have it with me but when I got home the first thing I did was check and see what type of cable it has. It has the larger cable so it works just fine just fine.

Shooter if you try your 1265 coil, before you put it on the 1270, air test a dime on your 1265 and then do the same on your 1270. If your coil has the small gray wire the air test distance will be about half on the 1270. Now if you have the larger wire it should be about the same.

So for my 1270 it will be fat cables from here on.

I have a 1260 X that has a 4 inch coil and I am having a hard time finding the stock 8 inch coil, you know someone who might have one that will get me going again with the 1260 X I was reading about your coils and was hoping one of them would work for mine.MarkCZ

No, those 1260's and the 1220's share coils but not with the other 1200's
Boy, that was a lot of help wasn't it. LoL!

I would just keep watching the forum classifieds and good ole fleabay.

One place I know of might have a coil that your looking for, try East Texas Detectors (Keith Wills) you can find them on the internet by looking up brokendetectors.com he specializes in fix'in up older units.

thanks Mark I will give them a call

 

[padgett79]

MarkCZ glad I called he only had 1 - 8 inch coil on hand for it, it is now on its way. thanks again for the info

Great! that will put another classic back up in use.

Your Welcome
