Jak, Dangerzone, and Jlyle,
Can you tell me if your strobes are within or outside of the range of serial numbers that were recalled?

Thanks

I had exactly the same issue, but only when trying to use TTL. After someone suggested shooting in manual at all times the red/green flashing went away and the strobes would last for a few dives (they were generally fine for 3 or 4 dives per day). It didn't solve the defect, but at least I could continue shooting. I was told that the strobes needed a firmware update and am currently waiting for them to come back from S&S.

Thanks. Can you tell me if yours were outside the SN range of the recall? Mine were outside the range by 200. Has anyone else had the reg/green flash issue with strobes outside the recall range?

I purchased two YS-D1s in July 2012 and took them to the Sea of Cortez in September. Both became inoperative (flashed the red-green "code") within 1 or 2 dives. Upon returning home, they were replaced with two new units (they were shipped in early October). The original two had SNs within the recall range. I was told, "There have been no problems with any of the units that were sold after the recall and outside that serial number range." I was on the Sundancer II in Belize last week where I got to try the replacement strobes for the first time UW. On the first dive, both of my replacement units malfunctioned exactly as the first trwo did and were completely inoperative! I did subsequent dives with three other brands of fully charged batteries; however, the problem always occurred. So this makes four strobes and two consecutive dive trips with a lot of really expensive UW camera gear and no photos!

I'd really like to hear if other YS-D1 owners are still having issues. Since my "luck" with them is 0 for 4, this has to be a widespread issue, or I really need to buy lottery tickets. Thanks.

I am also still struggling with this issue.. by the way I am going to use YS-DS1 with mirrorless LUMIX GX1 with nuticam.

I set it on DS-TTL II and had very good results with my 7D. The "other" slave seems to be for non-compatible cameras. I did have the lock up issue that was supposed to be fixed by the recall. Backscatter gave me two replacements. I'll test them in real water next month.

Thanks! I've played around with them above water and the light level control seems to work great in the DS-TTL mode. I'll be trying them UW next month.
