Well it use to be if you had a DM card you were covered and I still think it should be.
Personally, I don't see anything in the PADI syllabus >DM level that provides specific skills for solo diving. The dive experience for that certification is still ludicrously low, there isn't any level of precision taught with dive/gas planning etc, no training in redundancy and no self-rescue capability beyond the basic taught on the rescue diver course.
I've seen a lot of shoddy DMs wandering around thinking that their entry-level 'pro' card was some sort of license to do whatever they wanted underwater...solo, deco, cave, advanced wreck etc etc. Many of those were zero-to-hero types whose in-water skills betrayed a distinct lack of accomplishment. Even for those DMs with a wealth of experience - very little, if any, of that experience would directly prepare them for safe solo diving.
In the UK, I always found that a tech-level (AN/DP and above) qualification, along with technical equipment, would allow me to dive solo from charter boats. DM was never acceptable and rightly so IMHO.
Sorry if this cramps anyone's style, but I just don't see the DM cert as anything special - even more so when the card can be obtained in under a month from scratch by a non-diver.
