I think that the Etrac,Safari,Quattro can be as good on gold as any detector out there if the FBS picks the right set of frequenies.But you never know where you are at and you can not set it yourself.When I was at Outer Banks last year all I could find was small gold because I think everthing had been picked over and I mean real small gold with 6X8 SEF.I put pro coil on and could not find any small gold.Put small coil on started to find real small gold and plated fish hooks.Maybe SEF change frequeny selection who knows?
