I have the 4" coil that came with my F2 that I was wanting to put on my Delta 4000. The plugs are the same, I was just wondering if it would work or not. I don't want to hurt anything trying it out before asking.
You won't hurt anything but if you get one to work at all it won't be optimal.
Different frequencies and electronics, many have switched coils between brands and they work perfectly but many times something isn't perfect...depth, ID's, whatever.
Nothing to lose if you try and the screw on connectors are the same, however, big money for the correct Greek coil to fit on that Delta.
Model Frequency Coil Connector Type
F-2 5.9 Hz First type: plug in --- Revision type 2 screw on
