Machine specific Coil eg: Fisher F4

[Joe Prime]

Hi All, I;m a newbie to Geotech and have a question. Does anyone know(does anyone care) what the coil configuration is like for the Fisher F4 (11"DD, 10", 8",4")?

I'd be interested in trying to build a larger coil, perhaps 14".

Do you mean pinout, or inductances? I don't have an F$, but if the T2 uses the same coil, I could find out.

The F4 has the same frq as the Bounty Hunters and it's design was taken from the Radio Shack 3300. I would suppose it is a standard concentric coil design, that is the 10,8, and 4. Of course the DD design would be different from the concentrics.

I was told the T2 does not use the same coil as any other Fisher including the F75, which looks the same on the outside.
