Hello Waterpixelers,

Yesterday part way through a dive, my strobes stopped flashing consistently. If I'd take a break, sometimes it would work for a few shots, then stop working. I figured I just needed to change the batteries on my UW Technics trigger. I went out again today, with new batteries and started getting intermittent failure again part way through the dive.

The issue is for both strobes, so I ruled out the cables and strobes.

When the strobe's are failing, i took the cable off one strobe and there is no red light pulsing out the end. When it is working, I can see the light pulse.

I am assuming it is the UW Technics TTL Converter, but wanted to ask folks if there is anything else I should try to troubleshoot before sending it for service. The UW Technics is 1.5 years old and is the Canon version.

Thank you for any advice :)

I have had this inconsistency of similar nature with my A6400 and two UWT triggers. Never could find a reason.

Hi,

had similar problems with brand new UWT TTL Converter on Nikon D850. Tried to troubleshoot everyting with email support from UWT as it happen on a two month holiday in Philippines wihoutpositive result. Was lucky that I had the Nauticam converter as spare with me. UWT replaced the converter to a new one after holiday. The new one is working fine so far.

The other part of the equation is the Hotshoe cable. You could try on land to see if joggling the cable a little can reproduce the issue or not. Check and clean the hotshoe contacts on the camera as well.

I'll check. My camera is impeccably clean as I only use it within the housing, and have never had a drop of water ingress.
