Question Anyone using an AOI housing with flash trigger in cold water?

[webcubus]

I bought an E-PL9 and am running it in the Backscatter Octo Housing made by AOI. It has a flash trigger/vacuum seal system and the manual states it can operate down to 32F. Well, I hopped into 39F water this morning and the results were not good. The strobes fired irregularly (mostly not at all) and the green light only blinked a couple times. I charged it to full last night and tested both in the car before the dive and once I got home after the dive. In both cases it performed flawlessly - blinking green at a regular interval and firing the strobes 100% of the time. What's the coldest you've been diving with one of these housings (I assume most other AOI housings have the same or similar flash trigger, but please note the model)?

Not anything like 39, but routinely do 3 dives at 50F with no issues.
Should be like 94% capacity at 4C.

I have also had my E-PL10 / Backscatter Octo housing by AOI in 50F. No temperature related issues. The green light stops flashing after a while, I'm unsure how long that is, but the trigger continues to work after the light is out. I've spoken to a couple of other divers and they confirmed that on their rigs.

This combo seems to be very sensitive about anything to do with the optical cables, but you probably already knew that didn't you, and oh yes, the thing worked when dry. Good luck.
