concentric coil on F19 ?

[dfmike]

Anybody tried a concentric coil on the F19 and what was the result ?

I tried a concentric coil on the F19 and was unhappy with the results. Unstable for me and ID'd poorly. Others might get better results. The stock F19 coil can't be beat.

Thanks Shenandoah. I'll forget about using a concentric with it then. There's probably a very good reason why Fisher chose not to produce one for that detector.

I think I heard of read it is designed to use DD coils. Del, chime in. HH jim tn

Pretty sure it was designed around a dd coil.I've also read that large coils on the F19 were defeated by the quick recovery processors,but some folks report having good results with a 15" dd coil.
