There is obviously a lot of missing information here - and I think that critical amongst the things I would like to know would be group sizes and buddy arrangements. It isn't clear if his wife was also a qualified and experienced diver, but I would have assumed that on a "honeymoon dive" they would have buddied together and been diving as a pair.
So at the least she would know when they had become separated and if she had witnessed something happening before losing sign of him. I am surprised that if they were diving as a buddy pair she didn't raise the alarm earlier if they had become separated and she could not re-locate him. Sadly as they are Russian we may never know for sure due to the language difficulties, and she or the other divers are unlikely to make comments in any forum which is in English.
I know dive training is supposed to be universal but when I returned to diving I initially trained (and still dive) with a Russian owned and operated dive centre (last dive with them was yesterday). We see many divers trained in Russia and there is a very macho and Gung Ho attitude to many of them with scant regard paid to tables, depths and dive times. I know this was a shallow dive, in a relatively benign environment, and we do not yet have any idea what happened, but it may be that 150 plus dives and own gear does not necessarily equate to good diving skills. I will ask a Russian instructor I know if anything has filtered back through the Russian message boards and so on, but as this was a recreational dive abroad they may not have picked anything up either. - Phil.
