I just got back from a month of diving in the Philippines. On a rough crossing with 15 foot seas, the camera rocked enough in its bin to cause the sync connection to unscrew. I did not notice and on the next dive, towards the end of the dive, the sync connection to the housing flooded. The strobes failed to fire. I took the connections apart and there was a LOT of instant corrosion.
I thoroughly flushed both ends with fresh water a scrubbed all the gunk out. Once flushed, I soaked it in alcohol and dried it completely. When I put it all together, it worked fine for the rest of the trip. I do carry a spare, but tried with the original first.
Both the housing and the sync will be sent in for evaluation and repair.
However, two other issues I had I am not happy about. The new fitting just put on the top of the housing for my focus light almost IMMEDIATELY stripped out, making it useless.
And my newer DS 160 battery's latch broke sending the battery to the bottom. It was retrieved, but useless (luckily I carry a spare battery too). Seems Ikelite admits to having some faulty latches. It will be interesting to see how they plan to make that right.
Overall, I have been using Ikelite gear for 10 years and really love it. I don't plan on changing anytime soon. However, customer service is everything.
