We report an extensive study of the angular dependence of the de Haas-van Alphen frequencies for the field directions in the (0 1 0) and (0 0 1) planes, and the field dependence of the effective masses and frequencies below and above the metamagnetic transition field (Hm) in CeRu2Si2. The present study confirms our previous conclusion that the Fermi surfaces change from those of itinerant f electrons below Hm to those of localized f electons above Hm.
