Recently I have been diving while using Sea & Sea YS-D2 strobe. After 2 weeks of using the strobe it stopped firing (never flooded the strobe and used enelopes fully charged batteries, btw, I always shoot in manual). The constant light was still functional but the strobe flash just stopped firing. This was on Grand Cayman and my only option was to purchase a display model from Cathy Church shop in Georgetown. The new strobe survived another 3 weeks of photographing but I noticed that the recycle time of it started to increase. Other problem I found on both strobes was that when firing the strobe consecutively 10-15 times the strobe would stop firing and would need to recycle for about 10-15 seconds after which time it would start firing again. This happened on both strobes. Spoke with Sea & Sea today and their tech told me that that was not normal. Anyone had a similar experience? These strobes are $700 a piece and I am afraid they will not last me long time. How do these compare to Inon strobes?
