I see what you were trying to say but come on, everyone knows a rec instructor can't teach deco.

If one is teaching deco procedures for divers to do actual deco dives, it no longer falls into the realm of recreational. Recreational diving is diving when a direct ascent to the surface can be made at any time. The minute you introduce a ceiling, you have fallen out of that definition, regardless of what any agency would state to the contrary.



SSI offers a recreational specialty course to teach recreational divers decompression diving:

"You will learn to plan and conduct dives to a maximum depth of 40 meters with limited decompression using your recreational total diving system and a single decompression cylinder. You will learn and practice how to effectively use your dive computer features, including switching gases, gas integration, time-to-reserve, and time-to-surface. Using these computer functions will become second nature, enabling you to safely conduct dives with limited decompression without hours of dive planning. Upon completion, you will earn the SSI Decompression Diving Specialty certification and be able to explore stunning deep dive sites or larger wrecks without being restricted by the traditional no-decompression limits. The opportunities to expand your diving adventures have just got bigger!"

I am aware of that course. Regardless of what SSI states, is it not outside the realm of recreational diving as we define it?

Apparently you don't think so. That being said, I guess recreational divers can now have ceilings and do deco stops and if one comes to SB and asks what is the difference between recreational and tech, I would expect you to not be one of the people that mentions recreational diving is scuba diving to a a max depth of 40m within NDLs where a direct ascent to the surface can be made at anytime.

Who's "we"? Is it you Your Royal We, or, say, Cambridge English Dictionary that defines "recreational" as "connected with ways of enjoying yourself when you are not working"?

By one of those definitions the answer to your question is "no".

You know exactly what I meant.

PADI has almost the identical course, called Tec 40. it is described as transitional from recreational to technical. It allows 10 min deco max (SSI allows 15) and up t0 50% EANx (SSI is 40%).
Both courses are limited to 130 ft/40m.

I predict within a few years that "limited decompression" (up to 10 to 15 mins) will become normalized within recreational diving...but only if a stage cylinder of 40 cuft or larger is carried, and is part of the gas plan. And still within "recreational" depths (40m/130 ft).

Maybe this is useful but are there really a significant number of dive ops that will hang a decompression cylinder off the boat for divers with this certification but no technical certification?

Many do hang tanks for safety stop anyways.

Yes PADI does have the same course essentially but it is not a recreational course. It is a course that is part of their technical program. RAID also has a Deco 40 course and it is not part of the recreational list of courses but falls under the tech side due to divers no longer being able to make a direct ascent to the surface as now there is a ceiling involved.

Let me be clear, yes the industry talks about recreational depths but the same industry also talks about a direct ascent being allowed when it comes to recreational diving. However they do not have to go together. I have done quite a few dives that would be considered technical dives even though they were within the recreational depth limits. Far exceeding the NDL and use gases that contain more than 40% O2 for accelerated decompression. Any dive that goes past the NDLs and now requires stops based on a ceiling, IMO, is beyond recreational diving.

This course is still to recreational depth limits and using <40% O2 for deco. Deco time is very limited. No mixed gases beyond <40% O2.

Nitrox was considered "technical diving" before NAUI started to teach it to recreational divers in early 90's. I was in the first group of NAUI instructors that were certified to use and teach Nitrox (<40% O2) in 92 (or 90 but don't remember exactly now). ALL other recreational diving training agencies, primarily PADI, considered Nitrox as beyond recreational diving (in addition to being devil's gas) then. It wasn't until circa 1996-7 that PADI started its own Nitrox training for recreational diving.
