Heinrichs Weikamp have brought out a CLS Receiver to allow normal underwater strobes to be compatible with Nikon's creative lighting system. You still need to use a housed SB800 as the master strobe and the receiver allows the other strobes (as many as you could ever need) to all fire in concert.
Have any of the SB800 users out there (all +/- 5 of you!) tried this?
Regards
Jean.
