First dives with E-PL3 -- flash sync problems

[ProfF]

Just for the heck of it, you may want to have a look at http://www.scubaboard.com/forums/ol...-fiber-optic-ports-e-pl1-housing-pt-ep01.html ....
However, don't know how 2 strobes could be affected unless you have a dual cable plugged into one port (the weaker one) or you have a single cable in the weaker port and the 2nd cable is a daisy chain from strobe 1 to strobe 2.

Thanks, I read that discussion very carefully and plan to upgrade my toslink cable along the lines proposed there. As I said, I am not sure what exactly happened here. I diagnosed another problem (that in some of the pictures had light from one of the strobes) and then the other (the one I reported here) went away. The facts do not add up, and so either my recollection of what went wrong underwater were missing or the problem might come back to bite me :-(
