We have successfully managed to destroy our second last Sea&Sea YS-D2 strobe and are left with three Z-330s and one YS-D2 (two UW-photographers in family). The original plan was to replace a YS-D2, in case of failure, with a Z-330 (so that we have 2x two Z-330 for the rigs) and to use the remaining YS-D2 as an external strobe. This is not possible now, because of the discontinued Z-330. Also the YS-D3 II, which would be in a similar nice as the Z-330, is, because of the bad experience with YS-D2 (four flashes died since 2017), out of discussion...
Since I could not find a dealer who has some remaining Z-330 in stock (we are very satisfied with the Z-330 strobes), I fear I have to look for another, available model. I should also say that I plan to acquire a FF camera in the near future (Sony A7RV) and therefore a strong strobe model may be a good idea. From the data available in the Internet, I have compiled a table, for comparison of different models (corrections/additions welcome; did I overlook an important one?). Money is a factor, but not the most important one, quality and durability are rated higher. Also the GN is not very important, as this is measured under too many differing conditions (interestingly the weakest strobes have the highest GNs
):
From this comparison (and what I read here in this forum), I tend towards the Retra Pro X flash (output, color temp, o.k., HSS, but recycle time long, in comparison), but also the Seacam 160 (similar properties as Retra, but as far as I understand the accus are in the flasharms (=expensive to replace when accus have reached end of lifetime)) or the Ikelite DS230 (relatively strong and quick to recycle, but no HSS and optical triggering complicated) look attractive. The Isotta Red 64 may also be interesting, but it seems it does not exist yet...
What is Your valued opinion?
