Great video, good questions. Performance sounds good then. I like my Xp Orx. Tesoro Tejon is also favorite of mine and has a language to it's signal tone. Does the NFD 90 have a language with it's single tone.
Is the NFD 90 a vlf detector?
How soon will it be available?
Will be able in USA?
I might have missed the answers above.
I look forward to seeing and hearing more.
