This is untrue, I've had a Profisix for about twenty five years I also have three modern digital meters a Gossen Digi Pro, a Sekonic L-358, and a Kenko KFM 2100 (formally Minolta Auto meter V1), and they will all read light down to around the same level as the Profisix, down to -2EV with 100 I.S.O..
