Thanks. It's one of my favorites.

Same issues here with the YS-D1's. I'll jump in and have one or both strobes start flashing red/green with fresh batteries, and it's completely random as to when it happens. Sometimes I can get a whole dive, maybe even two, with no problems. Have to start the replacement process, but unfortunately I'm locked in for Lembeh and Ambon over the next two weeks with strobes that are completely haywire.

Have you experienced the problem in all strobe operating modes - manual, manual for pre-flash, and TTL?

This wasn't a mode issue. The first strobe had a short, the 2nd would flash red/green after on a few shots then stop working.

I took my two, new D1s to Cozumel for three weeks of intensive diving. One of the two units functioned property, the other had issues. Like Damselfish (above), the "bad" strobe would work before a dive with freshly charged batteries, but would sometimes start flashing red/green or green/green for no reason. The same "bad" strobe would also not fire in TTL when used with the "good" strobe; if I covered the "good" strobe I could get the "bad" one to fire...very strange. As soon as I returned to the States, I took the questionable strobe back to the store where I bought it and they sent it back to Sea and Sea for R/R. It's been two weeks...

I shot mostly with the strobes in manual mode because of the TTL problems I was having with the one.

Both of you have defective units. You will need to replace them.

I bought two -D1s in May. I've already had to deal with two replacements. First, one of the units I got in May developed a short and was replaced. Then after a couple weeks, the replacement unit would start flashing red/green on a fresh pair of batteries, so that's been replaced. Now the other unit I got in May flooded in the battery compartment at the beginning of the this month, even though the battery cap and o-ring were in perfect condition, the o-ting was perfectly clean and lubed properly, and the cap sealed correctly. Sea&Sea says they won't cover it under warranty and are basically blaming me for the flooding and want to charge me for the repair. While I have it insured and any cost will be covered, I'm not pleased with their dismissive attitude, especially since I've had to deal with 2 defective units already and quite frankly, they should be the party proving to me their products are more reliable than what I've seen so far.

Plus you don't want dust getting into the case.

I use i-Das arms. Generally less expensive, but the same as other Ultralight arm segments. The Stix floats fit them too if needed.
