Anyone done this course? Was it useful, or just a badge-collecting exercise? What specific skills were covered?

i'm probably going to invite a lot of flak but i think a lot of these courses are a waste of money and sound more like fluff than anything else. unless you are gonna do a "real" deep dive (deep enough to require breathing something other than air with planned decomp time + stage bottles, etc.), i really don't see why you need a course.
the only quantifiable difference that i can see between a 50' dive and a 100' dive is that you should monitor your pressure more frequently and be more aware of your breathing than usual (so as to conserve use of air). you don't need a course for this. you just need a briefing.
other than that, most people do not get narc'ed at that depth and hence would not benefit from having a trained instructor supervise the narc'ing so that you know what it feels like and know what to do.
therefore, look through the bull**** marketeers with their fancy ideas try to differentiate their products and increase penetration in their customer bases. i bet you will eventually end up doing lots of 100' dives on your own (with a buddy of course) anyway.
recently went a wreck dive (no penetration) with a whole bunch of OW divers, most of whom had less than 20 dives to 115'. Other than the possibility of someone getting narc'ed, in which case it is the supervising DM's responsibility to help prevent, I don't think any of them saw the dive differently, or even noticed that it was that deep.
i'm sure i am missing out on the rationale that PADI and other rec diving agencies provide for why a deep diving course is relevant. much appreciated if someone could enlighten me.
