probably same story with the crappy coil ,its the only one i havent tried from supplier i used because the 48khz gives naff discrim even on real deal . that said they got the 5" correct so it might need nothing doing .
remember all these machines were made for the african gold rush . it was only minelab and FT siezing crap loads from a wharehouse that made them start selling worldwide with slight name changes .
the minelab clones look very interesting too ,but heard minelab have some heavies hounding anyone who promotes them as good. dont think i want to upset them as well.
will just carry on enjoying my gf2.
