I just received the Nauticam MkII prototype strobe trigger and can confirm that, topside and on the 5D3, it fires my YS-250s perfectly. I do need to confirm this with a dive but it looks good to go ;-)
Hi Tim, I presume you've had a chance to try out the Nauticam strobe trigger prototype by now. How well do they work underwater? Seems like Nauticam is very quiet on this up till now while some of us are anxiously waiting for this!
