Fisher F 19 coil questions.

[TerryEastTexas]

First is there a 10" concentric coil that fits the F19. Such Fisher a Teknetics or Gold Bug. And if so is the performance hindered by the 10" coil?
Thanks for any info.

Technically it does not support concentric coils...only DD. However, some guys have put 7.7khz concentric coils from the F44/F22 and Greek series (Delta/Gamma/Omega) and had "ok" results. ID is usually off and depth is like 80%.

The results with my F19 and G2+ were terrible....like 60% depth....so I stick with the DD coils available.

As far as a 10 inch concentric...there is no round one...only the tear drop on the F44/F22 and the elliptical on the Omega and 8 inch on the Gamma and Delta.
