Fixed card ADF is dangerous in this day & age. I would never fly one. Ever. No reason to have one other than on a historical aircraft.
Put it on an HSI or RMI with moving compass and you have an approach that is 100x safer.
Not sure why everybody hates GPS so much. It's accurate, reliable and cheap(ish). Near ILS minimas to nearly every airport.
Edit: yes by near-ILS, I mean lined up with the runway at decent minimas (Yes I know they are a couple of hundred feet higher)
