More than "Advanced", but not really "Technical"

[Doc Harry]

1) Does this make any sense to aggressive recreational divers?

By definition, deco is no longer a "recreational" endeavor.

By definition, deco is no longer a "recreational" endeavor.

And every dive is a deco dive.

Thanks, doc, most helpful as usual.

So what term and what procedures do you suggest for the recreational diver that strays into and out of deco?

Must be why they made up techreational

"Idiot"

.. what...procedures do you suggest for the recreational diver that strays into and out of deco?

Seek remedial training.

By definition, deco is no longer a "recreational" endeavor.

To deter confusion due to the 'all dives are deco dives' logic, let's say "staged/mandatory-stop deco is no longer a recreational endeavor. Better still, let's say "decompression procedures training is necessary if the surface is no longer available as an immediate recourse for emergencies".

Must be why they made up techreational

The concept, as I see it, arose from the increasing trend for divers to apply technical mindset, equipment and/or procedures to recreational diving. Not vice versa.... which is an important distinction.

Doing technical-definition dives using a recreational mindset, equipment and/or procedures is just sloppy, complacent, unmitigated-risk diving.

Just me, maybe, but I always saw a three gas computer as air and two gasses. Air, EANxx, and O2. I'll only ever use two at a time, but it is nice to have everything loaded.

You could put in another gas so that in case of an emergency, someone brings a tank to you, you can swap.

That is actually a good question. I have a Uwatec SmartPro and a VR3. Love both. I'm probably one of the eight or nine people on this planet that actually like the VR3, but I do, a lot.

The SmartPro will get me out of light deco with a lot of whining. The VR3 can't be stopped, it just keeps on guessing no matter what I do. (I like to put it on air and dive best mix) Worst I get is an admonition to "use tables", -no worries, try this in the meantime.

So, realizing that I never really got upset about off-topic wanderings after a thread got so long that it just flaps in the current, what would anyone defend as a good middle-of-the-road DC for someone that wanted to regularly enter "light deco" without all the whining and complaining?

Light deco is a myth. Learn to do it correctly (with a 2nd tank) and make it part of the plan.

Agree with Andy: Idiot.

Lowvis, the idea that one should stray in and out of deco is fraught with danger.

1 - learn to be equipped and plan for that 'light deco'. If you are on a 120, and use 80cf and incur your "light deco" of 10 minutes . . . What happens when you reach that 10' stop for that 10 minute wait and your LP hose bursts? What are you going to do? Breathe off your buddy who also had deco? Now you're risking both your lives.

2 - Get multideco. It's cheaper to buy for the smart phone. Every time you switch phones, you have to re-purchase. It's worth it.

3 - bring the extra tank. Whether it is a pony you sling or something you hang off the boat at 20', have the stinking redundancy.

THAT is why you take the Adv Nitrox / Deco Procedures. So you know why this "light deco" is f***ing risky business.

If I set conservatism high on my recreational computer, all that I'm doing is limiting my bottom time.

If I extend my bottom time so that it is still within what is aggressive NDL, I will be in deco on my (conservatively set) computer. Dealing with this deco applies conservatism to my ascent. This also forces one to learn the concept of gas management.

All done within aggressive NDL limits. This concept must be way too complicated for the highly advanced recreational diver.

 

[DevonDiver]

Screwing, tricking or manipulating a dive computer algorithm (conservatism) to enable a given profile seems ludicrous to me. It's not what that conservatism settings are there for.

Set the conservatism based on your physiology, known DCI pre-disposing factors and desired level of insulation from DCI risk.

Dive safely within the no-stop limits that those settings dictate.

If you want to dive longer, use nitrox.

If you want to dive even longer, accept that further training and equipment are needed - and show the motivation and commitment to match your capability to your desired goals. i.e. take formal decompression techniques training.

By another definition, all diving is recreational unless you are getting paid to do it.

Again, I agree with Andy

If you are diving an aggressive NDL, then you are already pushing the envelope. Then incurring deco, and you are messing with your life, the lives of others on the boat, and your family.

Don't "force one to learn gas management", freaking LEARN it!! The only thing aggressive NDL limits give you is an opportunity to dance with the devil.

In other words, if you want more bottom dine, do it properly!
