Profoto flash heads include Pro-heads that plug into profoto generators. We also have D2 monoblocks and B1 and B10 off-camera flash units. The Off camera flash system from profoto are heads with on-board batteries, all AirTTL compatible for completely cable free shooting.
All heads have a 100mm barrel making them compatible with most reflectors and softboxes. The B2, B10 and B10 Plus can also be used with the lighter OCF reflectors and softboxes.
