I am a fellow marine photographer based in Mumbai, India and have extensively dived the Andaman and Nicobar Islands personally and on assignment for a coffee table book on marine images as well as a Fish Id book. There is only one liveaboard operator plying these waters from the Andamans. For some bureaucratic Govt. issues i believe they can only accommodate 8 divers at a time. What is your group size ? Some dive sites 6-7 are really excellent with one muck dive site. Some are good. There is also some great diving off Barren Islands etc. If you need help with booking this do let me know. I am currently working on a package for some south american divers but which is land based from Havelock Islands. Along with my partners who own a dive shop in India for the longest time http://www.barracuda...g.com/index.phpwe also arrange group dive trips for Indian divers all over the world via http://scubacentric.com/ So do let me know some more specifics and i could help the best i can ? You may mail me at email@example.com. Attaching some uw images from Andamans.
What i meant Bill is that i had a similar problem, albeit with Z240's and two were replaced. The strobes show that they are charging but the flash wont fire.. The focus light works. Inon replaced the strobes for me BUT they never reveal the problem ! The supplier though shared what Inon wrote to them and here is what they said :
When the camera battery is low , the trigger signal from camera is not recognized on Z240 strobe, Z240 recongnize it as "noise" And it cause some circuit trouble which affects the flash tube not being able to fire.
Therefore i shared this as the DS1 also use external batteries.
There can be a problem with charging the batteries. What batteries do you use and most important what charger ? If the batteries are not charged equally to the same level then there can be issues similar to yours. Make sure you use a charger that has a voltage monitoring system such as :
