So someone with 60 deep dives in the 30-40 m range (who has taken deep diving as one of the adventure focuses) is not as good as someone who has 60 deep dives in the 30-40 m range who takes the specialty during the DM.
It isn't about 'good'. It's about being prepared. Anyone can dive to 40m without deep training and get away with it. The more times they do it, the more comfortable they will feel doing it. However, they still don't have any solutions to potential problems and one day it will bite them in the ass.
The adventure dive (part of the AOW course) is for 30m. To exceed that, you need to do the full deep specialty. Also bear in mind that your insurance would probably only cover you within the limits of your experience AND certification. So diving below 30m without the deep course may leave you uninsured (this has happened to several divers already who were left with staggeringly large medical/recompression bills to pay.
Where I'm going, the following are offered:
Enriched Air, Gas Blender Nitrox and Trimix, Wreck, Deep, Night, Naturalist, Photography, Search & Recovery, Dolphin Rebreather, Equipment, Navigation, Videography
Gas Blender is a fun course and will do a lot to improve your knowledge of the gas behaviour prior to DM exams. It's rare course also, so not many (prportionately) people in the industry with those skills.
Of those, I'm already Nitrox cert'd and a DAN O2 provider (not sure if that DAN course is the same thing as what PADI will offer), and I have spent the last 3 years doing marine research, so I don't think I would benefit from the naturalist course - it would depend on the teacher's quals. But trying rebreathers is something that peaks my curiosity and something I'd like to learn about. Gas blending sounds interesting, too.
The DAN and PADI O2 courses are virtually identical, so not really worth repeating that course unless your O2 Provider certification needs refreshing (>2 years).
Semi-closed rebreather is a bit of a dead duck commerically nowadays - as the cost of CCR units has dropped. Few schools or resorts have these for rent, so it will be rare to get to dive the unit after the course. However, it will introduce some more in-depth theory on partial pressures etc. It's also nice to know the basics of how a rebreather system works....and it nice to get a few bubbleless dives in your log book.
Basically, I love diving, and my whole reason for doing this is not to start a new career right now but to get better at what I love and be the best I can be; however, I've carefully budgeted for this course, and now I'm having to consider an extra $50/$60 per specialty. So maybe now is not the time for me.
Well, cost is everything. If money was no object, we'd all be diving CCR at the Galapogos Islands
I have to keep reminding myself that the ocean isn't going anywhere. If I spend $300 on specialties, that's $300 less that I have to spend on diving over my Xmas break in Koh Tao and eating yummy Thai food. Sounds like I can take these specialties any time. It doesn't have to be during the DM. Sounds like I could pick one up in Koh Tao probably.
I worked for 2 years on Tao. Depending on which dive operator you choose, you can get some excellent (and cheap) speciality courses there. Most of the schools are nothing more than sausage factories for churning out OW students. Have a look at Master Divers (MV Trident) in Mae Haad for the Gas Blender or Discover Tech courses...well worth the time! You can also grab an exciting wreck dive with them on the technical boat. Seashell Divers do a good equipment course (ask if you can be taught by 'Mike' directly).
Titanium, small and with a good sheath. My Halcyon knife is still razor sharp and mint looking after 3 years of daily diving. It can also cut through a 1.5" rope in 3 swipes (not that I've ever cut anyone's anchor line )Now I need to hit the equipment forums. I need a new knife.
