interesting.i bought one of these last year assuming it is a DD coil..haven't used it much..how would a guy figure out what coil he has? hot spot on the coil is center...
The electronics of the 1200x isn't DD friendly, in other words they didn't make a DD coil for it. The use of the DD coils came along later in detecting history than the 1200x's.
Now, that being said! (This is my understanding of the DD coil's)
The idea of them goes WAY back, maybe into the 1980's but they couldn't make them work very well due to the older electronics of the day, so they just put the Double D concept on the top shelf for a later date. Well, that happened in resent times with the more modern electroincs.
So, I'm at lest 85% certain that the 5"x10" elliptical 1200 series coil isn't a DD coil, its just an elliptical! Another thing I noticed about the 5"x10" coil is Fisher made an early model Gold Bug that uses a 5"x10" coil as the Stock coil for it, in fact it looks just like the 1200 series except for the decal, the decla on one is much smaller than the other. Now the Gold Bug detector runs at a much higher frequency so the I don't see the coils interchanging with each other. But if your looking at buying a 5"x10" for the 1200 then I would say be careful you could end up with the Gold Bug coil!
