YS-D3s are known to be hard to trigger optically. With a D850, I assume you're using an LED trigger, right? It's probably putting out just enough light to trip their sensors, and when water gets into the connectors, it absorbs a little bit of light and that puts you under the threshold.

I've heard the same.  For whatever reason, the D3's trigger harder than earlier versions.

I've got 4 YS-D1's, one of which has a dead flash bulb.  All triggered fine with my Nauticam NA-D850 using the standard (non-TTL) flash triggers.

I'm suspecting that the triggers are right on the edge of having enough power to trigger the stobes, and perhaps even replacing the batteries will help.  There are TTL triggers available as another possible solution.

Are you using single-core or multi-core cables? If it's the former, the better light transmission of multi-core cables should be able to resolve your issue.

My rig is using fiber cables I ordered in 2016 for my NA-D810 housing, which used the pop-up flash as a trigger.  Never knew there were different fiber types out there.
