The F5 turns-On in d2 2-Tone so it works close to the F19. Lower frequency and no Iron Audio Volume, but otherwise works similar. Maybe a bit better in iron debris, and i do have the d3 and d4 Tone ID options if I want.

I also have the 5" DD on my Nokta Relic, a NEL 5" 'Sharp' for the Garrett Apex, too, so I am covered in the 5" coil category.
